Teo, you make some interesting points there. First and foremost, I'm trying to avoid having to start all over with the RC hobby just because I need (not want) to switch to electric. I don't want to go through some sequence of "first electric" "second electric" etc. before getting to fly (and build) the models I want to build. I've been flying and building (scale) for 10 years now. I don't want to have to go back to square one.
So that's the only reason I was considering putting a fixed electric system on an old beat up ARF. I flew the wings off that old ME (and by the way, I've now locked the gear down and never raise them in flight). I bought this ARF simply because it was cheap and I already had an engine for it. So if I could stick $100-150 worth of electric gear that I would later pull and use on a WWI model, I'd do that. If not, I'll just pull the servos and torch it (as per Art's suggestion). : )
