RE: What to buy
If you plan to stay in the hobby....or can afford it...My personal opinion...take a look at the Futaba 7 channel and see if you are willing to pay the extra $$$. If you stay in the hobby you will need more than the 6 for sure. I bought my 7 CAP only a few months ago....and already I have found myself needing the 9 Cap for its mixing functions. If you are in a club...ask around. Someone might have one in excellent shape at a good price.
ALso if this is your first build....take your time building it. Donto be inpatient and buy some of the stuff as you go. I found myself buying things i never even used. this hobby is epxensive enough. Id rather spend the money on planes.
