Duraplane
I have a couple of duraplanes that I fly when I want to really wring it out or fly in high wind. They handle the wind really well. I flew a few weekends ago in winds exceeding 30mph and gusting even higher and although it seemed to take forever to fly upwind it would scream going downwind. Landings were no problem in the wind if you were very gentle on the elevator input, pull back just a tiny bit too far and you were 50 feet in the air again.
I am intrigued by the suggestion of flapperons on the duraplane, I may order a new wing kit and convert it to dual aileron servos. It would also eliminate the problem of getting the rubber bands under the control rods. With practice the duraplane will land slowly though, but agreed, not as slowly as an LT40.
I will check into this, you have piqued my interest.
