Ace Ultra Sagan, Instruction

Page: 3 / 24

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.
