3 IN 1 UNIT ADjUSTORS
The 2 trimmers on the front of the '3-in-1' unit are factory adjusted and usually require no adjustment. The
status LED is next to the trimmers. The trimmers perform these functions:
Gyro gain. The left trimmer (GAIN) adjusts the amount of gyro tail stabilisation from 0 to 100%. 90%
is usually the best setting.
Yaw trimmer. The right trimmer adjusts tail trim (centring of the tailboom). NB if you adjust this
trimmer you must restart the helicopter in order to observe an effect on yaw trim.
Adjustment of the yaw trimmer has no effect until the li-po battery is disconnected then reconnected.
WARNING!
If your model tips over or crashes or rotors are physically stalled and prevented from turning, you must
immediately reduce throttle to avoid damage to the speed controllers and other components.
Crash damage is not covered by warranty.
damaGe pReVention featuReS
Unique features built into your Twister Medevac are designed to prevent accidental damage to the power,
drive and electronics systems.
LBW (LOW BATTERY WARNING) BEACON
The LED on the cabin of the helicopter will flash blue when the battery needs charging.
You must land immediately and recharge the battery. If you ignore the LBW beacon you risk damaging your
battery!
WARNING!
Damage caused to the battery is not covered by warranty.
MOPS (MOTOR OVERLOAD PROTECTION SYSTEM)
In the event of a crash or tip-over where the blades become stalled, MOPS cuts power to the drive motors
and electronics in order to prevent damage to these components.
If you crash the helicopter badly causing a blade stall, MOPS will kill the power automatically. You should
return the transmitter throttle stick to the low power position. The system will automatically re-arm some
seconds later.
