RE: type of controller?
Most pistal grips (steering wheel) are easier to hold than the stick radios. The pistal grip radio in not as bulky as the stick radio. In cars/trucks I perfer the pistal grip. With in the next few months I will be up-grading my radio to the Airtronics MX-3S. Its an FM radio that comes in 75mhz and 27mhz. And with this radio you will never have to change crystals. So if your at the races or around where alot of people driving RC Cars, you wont have to worry about someone having the same freq as you. All you have to do is turn a dial on your reciever and radio to change freqs.
