6 channels is enough if he chooses it to be so... the ailerons can be flown on one channel and wyed together, the elevators can be controlled with a reversing wye, and the gear can be controlled with a fifth channel.

So it can be done.

I like separating the channels so I bought a 9 channel radio as my SECOND radio. Don't advise the beginner to spend money they may not have. One or two crashes and they are gone from the hobby.

Someone else can take over... I am done with the thread.
