Maintenance and Security
A radio controlled model helicopter and a speed helicopter especially is not a toy. A mistake
can result in serious accidents and injuries.
Please keep the following rules always in your mind:
- During motor tests on the workbench, remove main and tailrotor blades and take care that
nothing touches the rotating rotor heads.
- On electric helicopters you cannot calculate the risk of a sudden starting motor. So move
quickly out of the range of main and tailrotor after you have connected the flight battery.
- If you adjust or program the ESC or FBL on the workbench, remove two of the three motor
cables to eliminate the risk of a sudden motor start.
- Keep a distance to the model of at least 5m (15ft.) to the model during hovering.
- Never aim helicopter towards a person or another living object with your model and keep a
distance to them of at least 20 metres (60ft).
- Remove all Lipo batteries from the model during stocking, and put them on a fireproofed con-
tainer on a fireresistant floor.
- Attention with kids and pets! Children are only seeing in the model helicopter a toy and do
not see the danger of the turning rotorblades. If you are flying and hear children then climb up
with the model over your head, inform the child, clear the situation and land on a safe place.
Similar rules apply to unroped dogs.
- In case of pending crash, activate throttle hold to turn off ESC.
