Mr. Mack-

You're on the right track. I think the 6EXAS is a great choice. I have been flying for the past 2 years on the 6XAS, its predecessor, and find it to be a great radio.

The issue is not really having to upgrade from 4 channels to 6, because most of the planes you will fly will only need 4 channels anyway. The more important issue is the computerized features, like end point adjustments, dual rates, exponential, multiple model memory, etc. You will use those features on your first several planes. The 6EXAS offers all those features at a great price.

The Kadet is an excellent trainer and the OS .46 AX is an excellent engine. Evolutions are fine, and less expensive. I have trained someone with an Evo engine. We had a little difficulty tuning it, but that could have been for any variety of reasons.
