This is a sophisticated hobby Product and not a toy. It must be operated with caution and common
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. 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 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 any optional 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 attention to the following areas. 

Maintain the proper mechanical advantage on all control surface linkages. 

Check the radio installation and make sure all the control surfaces are moving correctly (i.e. the 
correct direction and with 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. 

Never attempt to make full throttle dives! 

Large models perform much more like full-size airplane than small models. 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. 

Hardware checks 

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. 

Receiver Battery Selection

Be sure adequate batteries are used to power the receiver. It is recommended that a 6-volt receiver 
pack is used. The pack must have a minimum of 2700mAh capacity. Use pack of 3000mAh when super 
high torque servos are used. 

Range check 

Always range check the radio system per the manufacturer's instructions before the initial test flight 
and periodically afterward. 

Check the voltage of the on-board packs 

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. 

Preflight

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 between the 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.
