j) Practical Advice for the First Hover Flights
Your model helicopter in now ready for the first test flights and you can start training. However, even during flight
training, you should definitely keep in mind some basic things.
• For hover flight training, the tail of the helicopter must always point in your direction.
• To start, lift the helicopter approx. 20 – 30 cm from the ground, in order to be able to have it touch down quickly in
case of an emergency landing.
• In case of an emergency landing, do not retract the pitch lever too quickly, as the helicopter will touch down very
hard.
• If the rotors are blocked by an obstacle, then pull the Pitch stick immediately in the lowest position in order to switch
off the drive motors.
• At the start location, draw a marking on the ground and try maintaining the helicopter in a hover directly above the
marking.
Important information!
If the control LED (see figure 7, item 2) changes from green to red during flight, the flight battery is almost
discharged. When the LED starts to flash, land your model immediately to avoid harmful deep discharge of
the flight battery.
The closed design of the fuselage strongly heats up the electric motors during operation. This makes it necessary to
always put in sufficient breaks after flights. Let the motors cool off to ambience temperature before, e.g., starting again
with a second battery.
If after a few flights you develop a keen sense of your helicopter, you can carry out further optimizations.
