Your transition should be very easy. I do suggest an instructor and a buddy box for the first couple of flights though.

Except for the ailerons, I think you will find it easier. You should be use to the ailerons in a couple of flights.

You will also need a couple of flights to get used to the higher speeds, especially the landing speeds and the faster response times than MOST electrics have.

Because the plane is larger, it is easier to see. Since the plane is going to weight AROUND 5 - 5 1/2 lbs it is going to handle wind A LOT BETTER than a foamie.

I would talk to an instructor BEFORE buying anything. If possible, have a flight or two on the club trainer. I STRONGLY feel that you may be able to go directly into an advanced trainer such as the Avistar or into a low wing such as the SIG 4*, Thunder Tiger II or World Models Rambler 30 or 45 (45 has retracts).
