My opinion is that 4 channel is the way to go. First off, get an instructor wiith a buddy box. When you start training you will only be using the right stick on 2 channels any way. The left stick will be set at 1/2 or less and stay there for the 10 minute training session. After a flight or 2 you will start using the left stick to control speed and power. Now you are using 2 sticks and 3 channels. Now to start taxi runs using the left stick for steering and speed control. Now you are using 4 channels. Not too tough huh?!? For long term success I have found that you either get a decent setup and jump into it right or forget about it and go golfing.
