Alrighty, got a reply from Mr. Hostetler about the electric weight. 4.5lbs, of which 3lbs were batteries. The advantage to the electric, as far as weight goes, is it is somewhat more adjustable in that you can move the majority of the weight around. I could always use contest grade wood in the front half of the plane and AAA in the back to add a bit of weight in the back.

I'm thinking a 50cc will work super duper well, and will give me more than enough power to do whatever I want. Hmm, I wonder if BME will have their 55 out in the spring? [>:]
