If you as the Purchaser or user are not prepared to accept the liability associated with the use of this Product, you are advised to return this Product immediately, in new and unused condition, to the place of purchase.

SAFETY WARNINGS AND PRECAUTIONS

Protect yourself and others by following these basic safety guidelines.

1. This manual contains instructions for safety, operation and maintenance. It is essential to read and follow all the instructions and warnings in the manual, prior to assembly, setup or use, in order to operate correctly and avoid damage or serious injury.

2. This model is not a toy, rather it is a sophisticated hobby product and must be operated with caution and common sense. This product requires some basic mechanical ability. Failure to operate this product in a safe and responsible manner could result in injury or damage to the product or other property.

3. This model must be assembled according to these instructions. Do not alter or modify the model outside of these instructions provided by Flex Innovations, LLC, as doing so may render it unsafe and/or un-ﬂyable. It is your responsibility to ensure the airworthiness of the model.

4. Inspect and check for the correct operation of the model and all its components before every ﬂight.

5. If you are not an experienced pilot or have not ﬂown a high-performance model before, it is recommended that you seek assistance from an experienced pilot in your R/C club for your ﬁrst ﬂights. If you’re not a member of a club, the Academy of Model Aeronautics (AMA) has information about clubs in your area whose membership includes experienced pilots.

6. Keep the propeller area clear from such items such as loose clothing, jewelry, long hair, or tools as they can become entangled. Keep your hands and body parts away from the propeller as injury can occur.

7. Never ﬂy in visible moisture or submerge the airplane or any of its electronic components in water. Permanent damage to electronic components may occur, or corrosion of components may lead to intermittent failures.

LOW VOLTAGE CUTOFF

Li-Po batteries have a nominal (rated) voltage of 3.7v per cell, and fully charged, reach 4.2v per cell. Batteries are designed to be discharged below the nominal voltage, however, if they are discharged below 3.0v per cell, damage will occur and the pack will lose capacity. For best long term battery life, set a timer and land after a time that leaves approximately 15% of the battery’s capacity remaining.

Low voltage cutoﬀ is a feature that is built into the ZTW 50A ESC that is designed to protect the connected battery from being discharged too far and causing permanent damage to the cells. Circuitry within the ESC will automatically detect when the input voltage from the battery pack reaches below 3.0V per cell (average) and will remove power to the motor, but still deliver power to the servos so that a safe landing may be made. If the motor begins to lose power rapidly during ﬂight, the LVC has sensed that the total voltage of the pack has dropped below 3.0V per cell average, and the airplane should be landed immediately.

AURA 8 AFCS

The Aura 8 AFCS (Advanced Flight Control System) comes programmed and pre-installed in your Mamba 10 G2, making setup a breeze. This highly-reﬁned 3-axis gyro makes the Mamba 10 G2 ﬂy like it is a larger aircraft and in less wind. Thanks to the Aura’s advanced implementation, it not only enhances the ﬂying experience, but it never interferes with the pilot’s control.

The Aura 8 AFCS comes conﬁgured with Flight Modes (dual rates, expos and gyro settings) set by the Flex Innovations team, and oﬀers a great starting point for most pilots. Since these are already conﬁgured for you in the Aura, there is no need to set up dual rates or expos in your transmitter. Simply follow the Transmitter Conﬁguration Guide in this manual for complete details on the transmitter programming required for the Mamba 10 G2 and Aura 8 AFCS.

Visit wiki.ﬂexinnovations.com/wiki/Aura for the latest Aura-related product information and updates.

Description of Pre-Loaded Aura Flight Modes

Mode 1 (Sport): Gains are low and tuned for high speed aerobatics. Rates are low,

and exponential is tuned for comfortable ﬂight.

Mode 2 (High Speed 3D): Gains are moderate and tuned for high speed 3D

ﬂight. Rates are maximum and exponential is tuned for comfortable ﬂight.

Mode 3 (Slow Speed 3D): Gains are highest and tuned for slow speed 3D ﬂight

only. Rates are maximum and exponential is tuned for comfortable ﬂight.

Gyro oscillation will occur at mid to high speeds. Do NOT ﬂy at mid to high speeds in this Flight Mode.

NOTE - Rudder stick movement will also move ailerons and elevator. This is

NORMAL and is the pre-programmed mixing.

Each of the modes has been tuned by our team to oﬀer a solid start. Because tastes in control feel are unique, if changes in rate and expo are needed adjustments should be made through Aura. Changes on gain value may only be made through the Aura.

TRANSMITTER SETUP

WARNING

DO NOT ATTEMPT RADIO SETUP WITH PROPELLER INSTALLED. INADVERTENT POWER UP COULD CAUSE DEATH

OR SERIOUS INJURY

The included Aura 8 is designed to work seamlessly with all popular transmitter and receiver brands, however, transmitter setup is signiﬁcantly diﬀerent than when setting up a model without Aura.

When programming your transmitter, start with a new and freshly reset model memory. Make ONLY the changes shown in the Transmitter

Conﬁguration Guide.

1 JR customers should use JR XBUS Mode A, and follow the chart above. This is the preferred JR DMSS connection to Aura. 2 If you are using a Futaba transmitter, please note that some Futaba transmitters have the throttle set to reversed by default. We recommend

that you leave the reversing set to the defaults and reverse it if needed after testing. NOTE: do all throttle testing with the prop removed!

3 This time is a safe starting point for most pilots. This aircraft can typically ﬂy anywhere between 4 and 6 minutes (with 6S 1500mAh Li-Po),

depending on an individual’s ﬂying style.

FOR CUSTOMERS USING TRANSMITTERS OTHER THAN WHAT IS LISTED IN THE CHART ABOVE, PLEASE VISIT OUR WIKI

PAGE FOR INSTRUCTIONS SPECIFIC TO YOUR TRANSMITTER AND RECEIVER BRAND

HITEC – wiki.ﬂexinnovations.com/wiki/Aura/HitecSbusUse

The Mamba 10 G2 has an incredibly high roll rate. If you are a newer pilot, or after ﬂying feel that the roll rate is

too high, you can reduce the aileron end points (travel adjust, or ATV) in your transmitter by around 20%.

Page 9

CONNECTING BATTERY/ARMING ESC

Observe the following procedures to safely power up your model after it has been bound. Ensure propeller is removed unless this sequence is followed to power up before ﬂight.

1. Turn on the transmitter. Lower the throttle stick AND

throttle trim to their lowest settings. Be sure to wait for your transmitter to indicate it the radio signal is being broadcast before proceeding

If a battery is connected to the ESC with the throttle fully open on the transmitter, the ESC will enter programming mode. If this occurs, simply disconnect the battery, lower the throttle and reconnect the battery.

2. Ensure the aileron, elevator and rudder gimbals are centered.

3. With the airplane on a solid surface, connect the battery to

the ESC and wait. The ESC will make the motor emit a series of audible tones during its initialization process.

4. The ESC will make the motor emit a short, ﬁnal tone

sequence indicating that the ESC is now armed and that the motor will spin in response to throttle stick movement.

WARNING

When making adjustments to linkages, transmitter

settings, or the Aura 8 ﬂight control system, remove the

propeller to guard against accidental spool up.

WARNING

Hold aircraft securely when connecting the battery before ﬂight. Always ensure that the propeller is clear of any and all objects as

they may become entangled.

CAUTION

Always connect the battery when the throttle stick and throttle trim

are in the idle/cut-oﬀ position.

RECEIVER INSTALLATION/SERVO CONNECTIONS

Choosing a Receiver

Aura will auto-detect modern serial receiver connections. For use in the Mamba 10 G2, only a serial receiver connection or a Spektrum Remote Receiver can be used. Below are a few examples of serial receivers that can be used with the Aura 8. This is not a complete list of compatible receivers, rather a short list to assist in your receiver selection.

Spektrum Remote Receiver(s) - SPM9645, SPM9745 (QTY: 1 or 2)

Spektrum SRXL – SPMAR8010T, SPMAR9030T

Spektrum SRXL2 – SPM4651T, SPM4650

Futaba S.Bus – Futaba R7008SB, R2001SB, R6202SBW

Hitec S.Bus – Optima SL, Maxima SL

FrSky S.Bus – RX4R, RX6R

Graupner HoTT (Sum D of 8) – GR12L, GR16L

JR XBus (Mode A & Mode B) – RG012BX, RG613BX, RG821BX

Jeti EX-Bus – REX10, R9 EX, REX6

A PPM (8CH, negative shift, approximately 22ms/frame) receiver may also be connected into Port ‘B’, however Aura will not auto-detect and setup must be performed through the Aura Conﬁg Tool (Windows Application).

CONNECTING YOUR RECEIVER TO AURA

Note: The Spektrum 4651T receiver requires the use of a diﬀerent cable to connect to Aura. The cable is included with the receiver when it is purchased directly from Flex Innovations. You can also purchase the cable itself at ﬂexinnovations.com

(FPZA1039).

Spektrum Remote Receivers

If using a Spektrum Remote Receiver, connect it to Aura Mini Port A using the cable provided with your receiver. You can also choose to add a second remote receiver to Aura Mini Port B for added redundancy.

Serial Receivers

If using a standard serial receiver, connect the provided male to male cable to your receiver’s serial port. Connect the other end of the cable to Aura Port B noting proper polarity.

Aura 8 Auto-Detect

Once your receiver is bound, powered, and connected to the Aura, the Aura will begin the Auto-Detect process to learn what type of receiver you are using and set itself up for that speciﬁc system. Auto-Detect is indicated by a series of sweeping LEDs of various colors. After Auto-Detect is completed, verify that Aura is on and receiving data from your receiver by looking at the LEDs on the Aura.

Ready-To-Fly:

Solid Orange LED: Aura On and Calibrated

Solid Green LED: Aura receiving Valid receiver data

Possible Errors:

Flashing Orange LED: Aura Moved During Power Up

No Green LED: Aura NOT receiving receiver data

ESC THROTTLE CALIBRATION

In order to map the full range of the ESC output to your throttle stick motion you will have to preform an ESC throttle calibration. NOTE: Execute ESC throttle calibration with the propeller and spinner removed.

1. Power on your transmitter, DISABLE any throttle hold or throttle kill switches, completely lower the throttle trim and set the stick to full throttle.

2. Connect the ﬂight pack to your Mamba 10 G2.

3. Listen for the tones coming from the ESC through the motor, after about 2 seconds you should hear two tones.

4. Pull your throttle stick back to idle.

5. Listen for the ESC arming tones from the motor.

The ESC throttle range has now been properly calibrated, and is stored in the ESC's memory until it is calibrated again. You can repeat this process as many times as necessary.

Note: If you are using Futaba S.Bus, be sure to use the proper S.Bus port in your receiver. DO NOT use the S.Bus2 port, as it is not supported for use with the Aura 8. Refer to your manufacturer's instructions for proper S.Bus use.

Note: When using Spektrum SRXL to connect to the Aura, always connect the remote receivers to the Spektrum receiver, NOT to the Aura.

Binding Your Receiver

1. With the transmitter and aircraft powered OFF, place a

bind plug into Aura Port S8.

2. Power on the aircraft. Your remote receiver should ﬂash

rapidly, indicating it is in bind mode.

3. Bind your transmitter to the remote receiver per your

transmitter manufacturer’s instructions. This is typically done by pressing and holding the bind button on your Spektrum transmitter while powering it on.

4. Verify the receiver is bound by looking at the LED on the

Remote Receiver. This is typically indicated by a solid orange LED on Spektrum Remote Receivers.

5. Remove the bind plug from Aura Port S8.

Binding Your Receiver

Bind your receiver to your transmitter per your receiver and transmitter

manufacturer’s instructions.

LINKAGE SETUP

Mechanically adjust the control linkages so that the surfaces are neutral with zero trim and zero sub-trim. Final trim adjustments may be required during ﬂight. For more information on ﬂight trimming, please refer to the trimming section located on page 17 of this manual.

At the servo, the stock linkage attachment is a Z-bend located in the outermost hole in the servo arm for the rudder and elevator, and the center hole for the ailerons.

At the control horn, the Ailerons use clevises and the Rudder and Elevator use ball links. The stock attachment for the Ailerons and Rudder is

located in the outermost hole, and in the innermost hole for the Elevator.

NOTICE

The DS17HV servos installed in your Mamba 10 G2 are high quality, digital servos with metal gear train and ultra-ﬁne gear mesh.

This ﬁne resolution and high tooth count output shaft means that the servo arms pre-installed on the servos may inadvertently be

misaligned, yet appear properly installed. It is critical to ensure the positive, perpendicular orientation of the arm to the case to

ensure that the travel of the servos is even from side to side at extreme throws, particularly on the rudder servo.

CROW (AIR BRAKES)

Crow is activated using channel 6 from your transmitter, and is mixed so that when you advance the throttle to full, the crow is returned to neutral.

Futaba users that plug the ESC into their receiver directly may need to adjust the mixing in the Aura to get it to properly function. Please visit the Wiki page for more details.

CONTROL DIRECTION TEST

Refer to the chart below to determine the proper control surface directions.

If controls are reversed, DO NOT REVERSE CONTROLS IN YOUR TRANSMITTER OR IN THE AURA CONFIG TOOL. Email us at

support@ﬂexinnovations.com for corrective action. Note that BOTH the Transmitter Control Direction Test AND the Flight Controller

Sensor Direction Test MUST BE PASSED! IF EITHER ONE DOES NOT PASS, DO NOT FLY!

NOTE: There is pre-conﬁgured rudder to aileron and rudder to elevator mixing programmed into the Aura. Simultaneous

movement of these control surfaces with rudder input is intentional and completely NORMAL.

BATTERY INSTALLATION

In order to achieve the correct CG in the Mamba 10 G2 the ﬂight battery needs to be placed behind the hatch opening. In order to facilitate this a removable battery tray has been provided.

1. Push the spring-loaded battery latch tab back to release the battery hatch. Lift the hatch away from the fuselage, starting at the front.

2. Remove the battery tray by loosening the thumb screw. Slide the tray forward as you gently lift the tray away from the fuselage.

3. Install an adhesive-backed hook strip to the battery tray, and an adhesive-backed loop strip to the battery.

4. Place the battery on the tray, and secure it in place with the hook and loop strap provided.

5. Re-install the tray into the battery compartment by aligning the rear tabs on the tray with the appropriate slots in the fuselage sub-frame. Once seated in place, secure the tray to the sub-frame using the thumb screw.

6. Reinstall the hatch, and conﬁrm that the latch has positively engaged.

WARNING

When making adjustments to linkages, transmitter settings, or the Aura 8 ﬂight control system, remove the propeller to

guard against accidental spool up.

CAUTION

Always keep limbs clear from the propeller when the battery is connected. After the ESC

arms, the propeller will rotate when the throttle is moved. Unlike an internal combustion

engine, electric motors apply more voltage to counteract resistance, therefore any object

that is entangled in the propeller will be severely damaged before the motor will stop

PROPELLER/SPINNER INSTALLATION

Required Tools and Fasteners: #2 Phillips Screwdriver, 13mm Box Wrench, 2mm Hex Driver, (4) M2x8 Socket Head Cap Screws, M3x6mm

machine screw

1. Place the prop adapter on the motor. Ensure that it is fully seated.

2. Apply a small amount of blue threadlock to each of the (4) M2x8 socket head cap screws, and secure the prop adapter to the motor using a 2mm hex driver.

3. Install the propeller with the convex surface facing forward. The propeller size numbers are printed on the front face of the prop and should orient forward.

4. Slide the prop washer on the prop adapter with the widest face aft, followed by the propeller nut. Tighten the propeller nut fully.

5. Slide the spinner over the prop and prop shaft and secure it using the M3X6mm machine screw.

NOTICE

Spin the motor over by hand to ensure that the prop and spinner spin smoothly and true after installation.

CENTER OF GRAVITY

The center of gravity for the Mamba 10 G2 is located 2-13/32 to 2-9/16 inches (61 to 65mm) AFT of the LEADING EDGE of the BOTTOM WING, and is measured by lifting the completed aircraft upright, with all components installed, by the bottom wing. This measurement was

determined from many test ﬂights by designer and many time world aerobatic champion, Quique Somenzini. Lift the airplane from the underside of the wing to check the CG.

Setting the center of gravity is one of the most important steps for successful ﬂight, particularly with a new airplane. The Mamba is a highperformance airplane with large control surface throws, and a high thrust to weight ratio. These two factors combined make it a very enjoyable aircraft to ﬂy, but if the center of gravity is not within an acceptable range, it will make the airplane diﬃcult, if not impossible, to control.

NOTICE

The CG measurement should be made with the completed airframe with all components (batteries, servos, receiver, linkages,

screws, bolts, hardware, etc.) installed. Failure to do so will result in inaccurate measurement.

PRE-FLIGHT CHECKLIST

To help ensure a successful ﬁrst ﬂight, as well as many ﬂights after, perform a few simple pre-ﬂight checks to be sure the aircraft is ready to ﬂy:

1. Verify all control surfaces are properly hinged and are in good working order. Pinch a control surface between your thumb and foreﬁnger and stabilize the wing with your other hand. Give the control surface a good pull away from the wing. The control surface should not come unhinged from the wing. Be sure to avoid overstressing the part as an aggressive pull may cause the control surface to come un-hinged even though it was hinged properly. If hinging is loose, DO NOT FLY! Apply thin CA to the loose side(s) of the hinged to re-secure.

2. Verify that all hardware and other aircraft parts are properly secured, including those connections that require blue thread lock. This includes hardware and parts installed by the factory.

3. Verify your battery is fully charged and in good condition. Avoid using batteries with swollen cells, or batteries that do not charge back to their full capacity.

4. Verify the C.G. is in the proper location and the battery is secured in place.

5. Ensure the Aura is on and functioning properly. Power on your transmitter, followed by the aircraft. Ensure the Aura is calibrated properly and receiving a valid radio source (solid orange+solid green LEDs).

6. Verify transmitter stick inputs result in the proper control surface movements (reference page 13) and the Aura ﬂight modes work properly.

7. Verify aircraft movement results in proper Aura sensor corrections (reference page 14).

8. Verify the motor and ESC function properly. Point the aircraft in a safe direction. Hold the airframe ﬁrmly, smoothly advance the throttle to full and back to idle. Listen and watch for any odd or unusual behavior for the motor or speed controller.

AMA SAFETY CODE

When ﬂying your aircraft, we recommend following the guidelines set by the Academy of Model Aeronautics (AMA). You can ﬁnd their safety handbooks as well as more information on the AMA at their website, located at the address below:

FLYING YOUR MAMBA 10 G2

Selecting a Flying Site

Selecting a ﬂying site is critical to a successful ﬂight. Airplanes require a lot more room than other R/C products, therefore, a neighborhood or parking lot is less than ideal. A large open ﬁeld with short grass and generous overﬂy area are the best candidates if no AMA ﬁeld is available in your area. Know your overﬂy area ensure that there are no houses, playgrounds, or other buildings that may be damaged if the airplane were to crash.

Takeoﬀ

Taxi or place the aircraft on the runway centerline, with the nose into the wind. Select Flight Mode 1, verify the gyro kill switch is set to the gyro on position and set the throttle trim so that the motor spins smoothly at its lowest RPM without stopping. Smoothly advance to full throttle while maintaining directional control with the rudder and slight back pressure on the elevator. The airplane should lift oﬀ gently before the throttle is fully open. Fly in Flight Mode 1 until the aircraft is fully trimmed (see special trimming instructions), and you are comfortable with its handling, then explore the other modes as desired.

Flying

Altitude is your friend on the ﬁrst ﬂight. Briskly climb to a safe altitude and trim the airplane out. The airplane should ﬂy straight and level at 1/2 to 3/4 power with no hands on the transmitter. Try some basic maneuvers, and slowly progress into the airplane’s ﬂight envelope as you become more comfortable with the airplane’s ﬂight qualities and perfect your setup. Note: If at any time, such as after gain adjustments, you experience unexpected control system inputs or oscillations, use the gyro kill switch (CH7, Aux2) to turn the gyro oﬀ, land and troubleshoot the issue.

Landing

Be mindful of your ﬂight time and allow adequate battery reserve for a couple of go-arounds, if necessary, on the ﬁrst few ﬂights. Select Flight Mode 1 and slow the airplane and align with the runway, into the wind. The airplane should descend smoothly in this conﬁguration with proper airspeed. Once you are close to the ground, gradually close the throttle fully and begin to smoothly apply up elevator as required to arrest descent and the airplane should gently touch down with a short roll out.

Trimming

The ﬁrst several ﬂights on your new Mamba 10 G2 should be dedicated to trimming and setup. Fly the airplane at 2/3 power in any Flight Mode you are comfortable ﬂying in, and trim for level ﬂight. DO NOT CHANGE FLIGHT MODES. Land, adjust

linkages or execute Quick Trim (see below) and return the trim and/or sub-trim to zero and ﬂy again. Repeat process until the airplane ﬂies hands oﬀ, straight and level.

Transmitter trim or sub-trim will cause trim shifts when diﬀerent ﬂight modes are selected. To eliminate this trim shift, the model should be mechanically trimmed, or Aura “Quick Trim” may be used instead.

CAUTION

USE CAUTION WHEN FLYING YOUR MAMBA 10 G2 IN MODE 3

AT HIGH AIRSPEEDS. DOING SO CAN INDUCE CONTROL

SURFACE OSCILLATIONS AND MAY CAUSE A CRASH.

Aura Quick Trim

The Aura 8 features a Quick Trim Mode that eliminates the need for mechanical linkage adjustments during test ﬂights. Aura will learn the trim values from your transmitter, and apply them to the control surfaces at power up when enabling quick trim mode.

NOTE: Quick Trim can also be used BEFORE ﬂying to make small

changes to center the control surfaces before ﬂight.

1. Fly the airplane in your preferred Flight Mode at 2/3 power. Trim the aircraft with the transmitter trimmers and land. DO NOT CHANGE FLIGHT MODES.

2. Power oﬀ the Mamba 10 G2. Insert a bind plug into Aura Port S3 (you will need to remove the servo lead that is currently in S3). Check the transmitter is on and re-power the Aura to enter Quick Trim.

3. Wait 5 seconds for the Aura to completely initialize. Conﬁrm Quick Trim mode is active by checking the Blue LED is slowly ﬂashing.

4. Remove the bind plug from Aura Port S3 to save your trim settings. Re-install the servo that was previously removed into port S3. Removing the bind plug stores the current trims in the Aura. The Blue LED will ﬂash quickly after control surface trim values are stored. While the trim values are stored in Aura, they are not applied to the control surface(s) until the Aura is repowered.

5. Remove power from the Mamba 10 G2 and center all control surface trims on the transmitter.

6. Re-power the Mamba 10 G2. The control surfaces should be unchanged even though the trim has been centered on the transmitter.

7. Switch between other Flight Modes to ensure you do not see any changes in trim.

NOTE: QUICK TRIM MAY BE REPEATED AS NEEDED FOR FINE

TUNING, OR IF CHANGES TO THE AIRCRAFT ARE MADE.

NOTE: ENSURE AILERON/ELEVATOR/RUDDER SUB-TRIMS ARE

ZERO BEFORE FLYING FOR QUICK TRIM PROCESS

OPTIONAL WHEEL PANT REMOVAL

Required Tools and Fasteners: #2 Phillips Screwdriver, 1.5mm hex driver, (2) wheel collars

1. Invert the airplane and locate the two wheel pant retaining screws and remove them. Slide the wheel pants and tires oﬀ of the axles.

2. Remove the wheel from the wheel pant and reinstall on the axle.

3. Slide the wheel collar onto the axle with the shoulder (oﬀset) side towards the wheel. Tighten the set screw on the wheel collar.

For ﬂyers that want the lightest possible setup, or that ﬂy oﬀ of rough/unimproved ﬁelds, the wheel pants on the Mamba 10 G2 are designed to

be removable. Two additional wheel collars have been provided in the hardware bag to retain the wheels after the wheel pants are removed.

TIP: reinstall the wheel pant retaining collar and screws to prevent losing parts in case you wish to reinstall them.

TIP: use blue thread locker on the wheel collar set screw for added security.

AIRFRAME REPAIRS

The Mamba 10 G2 is molded from durable EPO foam and is repairable with most adhesives. Similar to building and repairing wood or composite airplanes, the correct glue for a given application is critical to the repair holding and not breaking again. For major repairs, such as a broken fuselage, epoxy is preferred because it allows time to correct any misalignment. For smaller repairs, such as a cracked control surface or small chunk of material missing from the airframe, regular CA is very eﬀective. The use of odorless (foam safe) CA is not required and not recommended on EPO foam aircraft because it takes a longer period of time to cure than regular CA and the bond tends to be weaker.

If a part is damaged too badly to be repaired, please refer to the table on page 3 for a complete listing of spare airframe parts.

NOTE: Avoid the use of CA accelerant in repairs. It can damage paint and will weaken the bond of the glue. If CA accelerant is used,

be mindful of the locations of CA to prevent premature bonding of parts, or bonding a hand or clamp to the airframe.

NOTICE: If a crash is imminent, fully reduce the throttle to prevent further damage to the power system and reduce energy to

lessen impact damage. Never allow the propeller to contact the ground under power, even idle.

CRASH DAMAGE IS NOT COVERED UNDER ANY PRODUCT WARRANTY.

Avoid keeping the airplane in direct sunlight when not ﬂying. Excessive heat can damage the airplane’s structure and UV damage

can permanently discolor decals.
