Yes the Sig SE is a very good airframe. I flew mine with an OS 46SX. It can fly slow or moderately fast. It's easy to transport because of the removable wing panels and easy to work on with an upright engine. It's not fragile but make SURE that you have low rates on when you first take it off. I had flown mine for about a year, very successfully, then went to my helicopter. When I went back to fly the SE for the first time in many months, I had highrates on the transmitter and the hairy flight lasted about 5 seconds.

I sure do miss that plane!!
