Got a OS.46fx in mine with the recommended CB Tatone pitts muffler in it. Great combination. All the above comments about snapping are the same with me. You want a snap happy plane? This is it. This is a very performance related plane, a real sleeper. It can be pretty evil at times. I've found that the bulk of my ground handling problems start after the landing gear speads a bit. Turns it into a ground looping. Squeeze them back together a little and its ok for about 4 or 5 more landings. Right now mine is down for recovering and replacing the nyrods and new lander gear. It developed a recentering problem over the years, going back to pushing rods. And I hate moneykote, new covering will be solartex and paint.
I built some floats for but decided to wait on that experiment.
