Problem
Roll on takeoff
Tail is not holding
Oscillations
The helicopter has
reduced fl ight time
or is underpowered.
High motor
temperatures
EN
Possible Cause
Letting the helicopter spool up slowly
can cause vibration, which will cause
an unwanted roll.
Your helicopter can get stuck in the
grass very easily because it is so
lightweight.
When the throttle hold is on, the pitch
range is not equal.
Tail rotor gear is stripped/slipping.
This may not be apparent until, with
the helicopter powered off, you hold
the main rotor head still with one
hand and GENTLY rotate the tail rotor
with the other hand using light pres-
sure. The tail should not spin freely.
For the sake of aerobatic
performance, we have found that
an occasional "wobble" during a
maneuver was preferred over the
performance with a lower gain value.
Flight battery charge is low.
Inadequate power to fl ight battery
charger.
Flight battery is damaged.
Flight conditions might be too cold.
Flying back to back fl ights without
letting the motor cool.
Solution
As soon as the blades start spinning, the pilot
needs to start fl ying the model.
When taking off with your helicopter, increase the
throttle quickly to pop it off the ground.
Take off from a smooth surface such as concrete.
Activate throttle hold, adjust all three cyclic
linkages to achieve 0° pitch at half stick
The torque shafts have a fl at side, which matches
a D-shaped hole in gears C and E which may strip in
the event of a crash or rotor strike. Replace the
gear if it is slipping.
Gear A on the main shaft can strip in the event of a
rotor strike; carefully inspect it and replace if teeth
appear to be worn or chipped.
The "gain" or sensitivity of the gyros on your heli-
copter board come pre-set from the factory at a level
that is suitable for most pilots. In certain conditions,
the user may wish to adjust those gains. If the heli
oscillates, the gain is too high and should be reduced.
If the heli feels mushy and not locked-in, an increase
in gain is required.
Completely recharge the fl ight battery.
Make sure the AC power supply, charger and adapter
cord are connected.
Replace the fl ight battery and follow the fl ight
battery instructions.
Make sure the battery is warm (room temperature)
before use.
Allow the motor to cool between fl ights. Generally, we
have found that the acceptable motor temperature is
approximately 160°F (71°C) depending on ambient
temperature.
