RE: Tweaking walkera radio system! plz help
Dima,
The first thing that you need to do is make sure that you have a surface frequency. I don't know abou Canada, but in the USA 72mhz is for aircraft only and 75mhz is for surface use. 27mhz can be used for both. If you use a aircraft frequency for surface, you may cause someonr to crash their plane. We have a $10,00 fine here for offenders. The gear switch usually operates channel five on the receiver. You could use a slide switch with a servo to reverse the polarity of your motor for reverse. A transmission could also do this.
