I second the Tiger2 or the Super Sportster. The Tiger lands about as slow as your Avistar and the SS likes to land a bit faster but not a lot of difference. Both will fly pretty fast but then so will your Avistar at full throttle. If you can handle that without sweating then either of the other 2 shouldn't be a problem for you. If ARFs don't bother you a World Models Super Sports 40 is very well built, inexpensive and wold be a good choce for a 2nd type plane. I would keep the Avistar as is and get a new engine for your 2nd. Its always nice to have 2 planes at the field. [8D]
