The F20 is 6 years old and original. The Ultra Sport was given to me from a guy who had it in poor condition and needed a rebuild and covering. The engine and components in the Ultra Sport came from that gray f20.

The Gray F-20 went in hard and fast on it's maiden run. It was a Cermark and the elevator fluttered and killed the servo. I don't attribute that to pilot error. It was a very spectacular crash. It was so good that I really had no emotiions for the loss. I had just finished trimming and opened er up to come around for a high speed pass. I was way up their coming in at a 30 degree angle and it never pulled up. Nailed it right in front of us. Ultra sport has been fine for 2 years now.

I think that gray one is still on Jetts webpage somehwere.
