I used to fly a Hobbico Starfire which is very similar design and contruction to the Twinstar but only one motor and I loved that plane. I flew the crap out of it for about 4 years and was really easy to fly and land. No bad tendencies at all. It made me look like a better pilot than I was at the time. The only complaint was the sticky tape covering which I think the Twinstar has as well. It would peal up around the trailing edge and corners and once fuel got under there it was tough to repair.

About 5 years ago, a guy at our club had a Twinstar and he really liked it. From his explanation it seemed to have the same good characteristics as my Starfire.

I hope this helps.
