R/C newbie looking for opinions-cheap radio!
Jason,
You need to purchase an FM **GROUND** system on 75Mhz. You MUST use 75MHz for your model, you cannot use 72MHz which is an aircraft band. You could use 27MHz, 49MHz, or 50MHz but don't for reasons I wont get into here.
Channels can mean two diff things...
1) what channel are you on? this is a specific frequency within the frequency BAND, such as channel 65 is 75.xxx.
2) the number of separate controls on the model. So if you are going to have (1) throttle, (2) steering; (3) engine cut off, then you need at least a 3 channel controller. MOST brands the name of hte model tells you its number of channels. I used to work for Futaba so i'll use their examples. 3PDF, 3PJ, 3PJS, 3PK are all 3 channel systems of varying complexity.
