I have had a couple of Sonic 25 low wing models. One I built as electric with an Atlas .46 motor from Hobby-Lobby and 12x8 prop. Conversion was easy by usong standoff's instead of the motor mount. The battery was placed where the fuel tank would go, by installing a flat piece of ply acrossed the fuselage and ribs. It was real easy to handle, although it floated like a butterfly, but had enough giddyup to do anything I felt I was big enough to try.

The ARFis extremely well built, and an easy build. I am still flying one with a GMS 32.
