Hi I am trying to design a RC mini helicopter. I dont want to go much into its mechanics, as I am not a Mechanical engineer !!! First I want to start with its electronics, that is the transmitter and receiver. I have some ideas on the paper but they are not helping me at the moment ! I jot down some basic ideas, see what you guys think. 3 channel Tranceiver (maybe 6) Main Channels : Up/Down --- Forward/Backward ---- Left/Right Variable resistors for the inputs PWM techniq to control the power delivered to the motors Two motors for the main and the tail rotor The problem is how to trasmit and receive the PWM signal , or is this done in a different way ? Thank you
