not a must starting with a trainer?
but the problem is, if you learn to use the copilot, when it is not available you will not know what to do. to be honest, if you get a trainer, the copilot is not necessary. you see, in order for the copilot to work, the sticks have to be centered. that means, let's say, you are landing, but in a nose down attitude. you want it to stay that way, so you center the sticks. if you have a copilot, it will return it to level flight. no good. just learn with the trainer. it seems intimidating, but if you get a good instructor, it is not a problem at all.
