RE: Here's a Simple & FREE First Foam Build Plan! Cool Looking Plane Too...
Never too late to join in on this build. Welcome. The original plans (page 1 link) call for using a 400 direct drive and an 8 cell nimh pack. I'm sure you can mix it up a bit, using probably even a 6 or 7 cell nimh pack. A 480 should also work fine with it. In fact, I'll be helping a friend put his stock Stryker electronics into one. It uses a 480 and 7 cell nimhs. Change the jumper on the stock RX to get a elevator/aileron configuration (I think this is the same RX found on the J3 Cub, P51, and a few others if you have a junk Hobbyzone/Parkzone plane laying around).
