been there done that a1. I like the stump pullin four strokes myself. There's something about watching my plane instantly accelerate vertically when I pull the nose up and hit the gas. There are lots of magnums running at my field and they're all pretty dogone nice running engines. I think you'll like that 80. Do yourself a favor when you get the money though. Go out and try one of the high end engines like ys or saito (yeah I'm a ys fanatic).
