Rcpilot,
I had this plane few years back. It had OS 61SF with Hatori Tuned pipe on it. Mine had a foam wing and it was kinda heavy, so the snaps were wild!! infact uncontrollable! otherwise its a very smooth aircraft to fly. Landings are extremely stable. No bad habits as such. Loops, rolls, inverted, vertical were great. Knife edge was ok. And yes, its a floater!! So I had flaps on it too!
