Attention !

This jet aircraft is a high end product and can create an enormous risk for both pilot and spectators .
If not handled with care & used according to the instructions. Make sure that you operate your 
Viper according to the laws and regulations governing model flying in the country of use. The 
engine, landing gear, servo, linkages and control surfaces have to be attached properly. Please use 
only the recommended servos and accessories. Make sure that the Centre of Gravity is located in 
the recommended place. Use the nose heavy end of the CG range for your first flights. A tail heavy 
plane can be an enormous danger for you and all spectators. Fix any weights and heavy items like 
batteries , very securely into the plane. Make sure that the plane is secured properly when you start 
the engine. Have a helper hold your plane from the nose before you start the engine. Make sure all 
spectators are far behind, or far in front of the aircraft when running up the engine. Make sure that 
you range check your R/C system thoroughly before the 1

st

flight. It is absolutely necessary to range 

check your complete R/C installation first WITHOUT the engine running. Leave the transmitter 
antenna retracted or incase of 2.4ghz depress the range check button and check the distance you 
can walk before FAILSAVE occurs. Then start the engine, run at about half a throttle and repeat the 
range check. Make sure that there is no range reduction before FAILSAVE occurs. If the range with 

engine running is less then with the engine off, please don’t fly at that time. Check that the wing 
and stab retaining bolts are tight and that all linkages are secured. Please don’t ignore our warnings, 

or those provided by other manufactures. They refer to things and processes which, if ignored could 
result in permanent damage or fatal injury.

Important/General Notes

Servo Choice

We strongly advise that you use the recommended servos and equipment listed in the manual.

Servo mounting

Fix all the servos into the milled plywood  or aluminum servo  mounts without rubber bushings if 
possible

Building Sequence

The actual building sequence is your choice but it is usually most efficient to start as suggested in 
this manual, which has been created by building several airplanes by several experienced modelers.
