Hello again,
I received the heli without the remote control.
It says the remote control should be at 35Mhz, channel 72. What's channel 72?

Is the following remote control suitable?

Graupner X-412 UNIT 35 MHZ GR.-NO. 4713
Micro-computer radio control system with 6 control functions. X-412 COMPUTER SYSTEM 6-channel FM radio control system. 35 MHz band.

Regards,
Alex
