Since I am in the process of hopping up my npede, I was wondering if I should buy another radio as well. In the past I haven't had many problems with my stock radio and all I do is bash; mostly running up and down the road. I have the stock transmitter and receiver right now with a futaba S3004 BB throttle servo and hobbico cs-55 steering servo right now I think. I was thinking of getting a JR radio for $180 but i'm not sure if i need it? What kind of radio systems do you guys have and recommend?
