Sargent, I had a Twist also, with Saito 82 in it. It was a real fun plane. I thought it was very close to the UCD46. I almost felt as if I had duplicate airplanes so I sold it. The twist would do a wee better inverted rising flat spin, but everything else the UCD does better. So I opted for the UCD. I've been happily crashing them ever since.
Thanks,
Barry
