OXY 4 MAX - FLY STYLE / HEAD / TAIL SETTINGS
In order to choose the best setup for your OXY4 MAX, and optimize performance, it is important to know some basic information:
1- The Motor Kv - See your motor specifications.
2- Battery Pack - (3/4S or 6S)
3- Your target head speed, If you use a head speed calculator, use
110 Teeth
for the main gear and one of the available pinions.
Or use this simple formula:
If you use governor, in order to assure that RPM will be constant during the fly, set a gear ratio to have theoric Max RPM approx 10% higher than your expected governed RPM. Your TX Throttle value should be set
between 75 to 85%
Example: Target RPM Governed at 80% throttle value = 3500, the theoric Max RPM should be approx. 3850.
This formula and value can be effected by many factors such: Battery quality, Battery C Rate, Motor Power and Fly Style. In any case can give you basic information choosing your Motor KV and Pinion (Gear Ratio).
Table below will give you basic suggestion about RPM and Tail Setting (tail pulley / tail ratio) in order to guide on your OXY4 MAX Fly Style needs.
OXY 4 MAX - ELECTRONICS AND POWER SUGGESTIONS
Head Speed Note: Although OXY 4 MAX can handle very high Head Speed, we suggest not to exceed 4000 RPM to maintain a good compromise between performances
and efficiency. Our Test confirmed that OXY4 MAX can perform form 2000 up to 4000 RPM, for more information about your personal Fly Style need and relative Head and
Tail Settings, see above Info and Table: “Fly Style - Head - Tail Settings”
CONFIGURATION EXAMPLES:
Since the OXY 4 MAX is a high performance 3D RC helicopter, we suggest using high quality electronics and power components including Servos, FBL , Motor, Battery and ESC.
Remember that OXY 4 MAX is a 380 RC Heli - use light components to maximize flight time and performance. Always consider the acceleration G force in fly, few extra gram can
become Kg during some maneuvers, compromising the best performance. Always choose the electronics and the power system suitable for your fly style, “more is not always better”!

Use a Screw Driver to check
Belt Tension (suggested max
deflection is 1mm)
- Note: We recommend a tight
Belt tension.
- If spool up get difficult, may Tail Belt
is over tight, recheck and eventually
loose Belt tension little bit
- Check the Belt tension again
after the first 2 flights.
- With a new Tail Belt, when the
head is rotated slowly, it is normal
to hear a tooth sound as the belt
engages with the Main Pulley. This
sound is normal and will disappear
after a few flights and the necessary
"break-in".
- Be sure the boom is assembled and installed correctly.
- Loosen the tail boom by loosening the eight M2.5x8 Hex Cap Screws.
- Adjust the Belt tension by pulling on the Tail Boom.
- Tighten the eight M2.5x8 Hex Cap Screws.
- The belt must have good tension. We suggest re-checking after a few
flights. We suggest to check belt tension often, before each flying session.
- If spool up get difficult, may Tail Belt is over tight,
recheck and eventually loose Belt tension little bit
- If the belt is often loose, you should check the lock system or belt integrity.
- Tests show that a hard 3D pilot can perform over 400 flights before the belt
will fail. We recommend replacing the Tail Belt after 300 flights, even if it
does not show wear, to avoid it breaking unexpectedly in flight.
- After a crash, spend some time checking Belt integrity and replace if any
teeth are missing.

Fine Adjust Shims:
In order to give fine adjustment options,
the extra Hardware Bag contains extra
Shims 4x6x0.1. Start assembly
with one (each side)pre installed shim.
If the Main Grips have
sideway play, add shims as required.
Each Grips must have the same number
of shims. If you add one shim on the left
side, you need to also add one shim on
the right side

You should now do some initial setup of your FBL unit and servos.
- We recommend you select a new model in your transmitter, and reset your FBL unit and start with a clean setup in it as well.
- After binding your transmitter to the receiver system used with the FBL unit, work your way through the FBL setup instructions to the point
you plug in your servos.
- Now set your collective stick in the middle position, and position the servo arms as close to the correct positions you can on each servo
see the following pages for arm orientations on the various servos.
- Next confirm the servos work in the correct direction, then return the collective stick to the center position.
- Now use your FBL unit to trim the servos so the arms are exactly horizontal (see pictures below).
- This procedure varies between units. Carefully label the position of the servos, then proceed with the installation of the servos as shown.
It is really important the servo rods screw onto
the linkages the same amount. The Plastic
ball links have a Lynx logo to give you
information about turn adjustment, but have
a symmetrical ball socket shape and can be
installed in either direction to achieve the
best fine tuning.

Use 3 x cable ties, to secure the Throttle ESC wire to the main frame. Use the Frame
built-in socket for best holding. In this Step connect the Motor and ESC Wires but don't
secure yet. Wait till the final motor rotation check, once the FBL system is set up.
NOTE: To reverse Motor rotation direction , just switch 2 of the 3 wires.
Be carefully Motor wire
and ESC will not touch
Motor/Pinion.

Tail blade need be loose. Set it free to rotate.
About lock thread, to assure the Screw M2x 10
use it but carefully. Apply small amount of lock
thread NOT in the Screw but in the Tail Grip Thread,
using a tooth pick. Be careful about lock thread
contamination on plastic tail blade, lock thread
contains chemical that effect plastics, reducing strength.
After assembly clean carefully any lock thread
excess to avoid contamination effect.

Chapter 19: Adjustment Servo With Leveler
Before Fly:
Now complete the setup of your FBL system. In the Accessories Bag you will find an Oxy 4 Swash Plate Leveler.
This Tool is designed to fit under the Swash Plate without disassembly any parts. This simple tool will both level the swash and give
the Zero Pitch Position.
Starting gyro gain: The Oxy 4 was designed around famous FBL Systems (IKON / Brain / mini V-Bar), and we suggest you start with
the following standard set up and adjust after test flying.
Cyclic Set Up:
Use suggested settings for 450 Helicopters and adjust after test flights.
See our table on page 6 for RPM and Pitch Settings. Cyclic Max pitch should be +/- 10.5 deg.
Tail Set Up:
Use the suggested settings for 450 Helicopters
BUT
start with a
LOWER
Tail Gain ( Increase after test per need )
IKON / Brain = 20%
Mini V-Bar = 250 Heli suggested gain.
Lift up swash plate
as shown to have
space for inserting Leveler.
Rotate Leveler as shown
Lower Swash Plate down
untill Swash Plate
touch Leveler as shown.
