sense and 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. This Product is
not intended for use by children without direct adult supervision. The Product manual contains
instructions for safety, operation and maintenance. Itis 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 injury.
This model is controlled by a radio signal that is subject to interference from many sources outside
your control. This interference can cause momentary loss of control so it is advisable to always keep
a safe distance in all directions around your model, as this margin will help to avoid collisions or injury.
Always operate your model in an open area away from cars, traffic, or people.
Never operate the model into the street or populated areas for any reason.
Never operate your model with low transmitter batteries.
Carefully follow the directions and warnings for this and anyoptional support equipment (radio,
engine, chargers, rechargeable battery packs, etc.) that you use.
Keep all chemicals, small parts and anything electrical out of the reach of children.
Moisture causes damage to electronics. Avoid water exposure to all equipment not specifically
designed and protected for this purpose.
Safety Precautions and Warnings
We guarantee this kit to be free from defects in both material and workmanship at the date of purchase.
Limited Warranty & Limits of Liability

As a large model, the airplane is critical of proper battery use, control linkage setups and flying
techniques. Please pay particular attentionto the following areas.
Check the radio installation and make sure all the control surfaces are moving correctly (i.e. the
correct direction andwith the recommended throws). Test run the engine and make sure it transitions
smoothly from idle to full throttle and back. Also ensure the engine is tuned according to the
manufacturer’s instructions, and it will run consistently and constantly at full throttle when adjusted.
Check all the control horns, servo horns, and clevises to make sure they are secure and in good
condition. Replace any items that would be considered questionable. Failure of any of these
components in flight would mean the loss of your airplane.
Large models perform much more like full-size airplane than smallmodels. If the airframe goes too
fast, such as in a high throttle dive, it may fail. The model should be flown like a full-scale airplane.
Throttle management is absolutely necessary.
Double-check the setscrews in all control horns to be sure they are very tight. Periodically check
these to be sure they have not loosened over time. Always use threadlock on metal-to-metal fasteners.
Be sure adequate batteries are used to power the receiver. It isrecommended that two identical
6-volt receiver packs are used. Each pack must have a minimum of 2700mAh capacity. Use packs
of 3000mAh when super high torque servos are used.
Always range check the radio system per the manufacturer's instructions before the initial test flight
and periodically afterward.
ALWAYS use an ESV with a 1-amp load to check the receiver battery packs and the ignition pack
before each and every flight. If there is any doubt that the packs are questionable, DO NOT FLY
until the packs are recharged.
Maintain the proper mechanical advantage on all control surface linkages.
Never attempt to make full throttle dives!

Step 2
Fully assemble the model. With a helper, lift the airplane with your index fingers to find the balance
point. The balance point (CG) should lie betweenthe two marks on the wing. If not, try to move some
parts such as batteries to different position, or add the necessary weight to the nose or tail to obtain
the correct balance.
Congratulations on the purchase of this model airplane. You will enjoy one of the most thrilling
experiences the radio control hobby has to offer.
The product is a professionally built, radio control model. It is very important that you operate this
model responsibly. Please read this instruction manual thoroughly and follow the directions.

Control Throws
Correctly balancing an aerobatic model is critical
to its performance and flight characteristics.
Checking the balance on this model is bestdone
with two people.
Measure back 30%-33% of the whole wing root’s
length from the leading edge and mark the CG
range with a felt-tipped pen at the wing tip. This is
the recommended center of gravity (CG) range.
Step 1
Recommended Center of Gravity (CG)
A 7-channel or greater computer radio is highly recommended. This allows the following features:
• Mixing the right aileron to the left aileron (flaperon mix)
• Electronically adjustable aileron differential
• Mixing the right elevator to the left elevator (dual elevator mixing)
• Independent travel and trim adjustments of each elevator half
• Mixing the right rudder servo to the left rudder servo (not required when using a single rudder servo)
When you use a 7-channel or greater computer radio, each servo is plugged into its own separate
channel. Consult your radio manual for specific details on hookup and programming.
