RE: Sig Mid Star 40 as second plane ???
After a long stop and start build, I finally finished my Midstar last Fall. It's a fun building and flying airplane. I enjoy doing Cuban's and hammer heads with it. It will hold a knife edge and snap roll real fine, although I'm a little afraid to do this, until I reinforce the tail with tri stock or bracing wires. I also enjoy practicing side slips with it. Simple stuff to some. But that's my style I guess. This plane makes it so easy.
BTW, I believe the Midstar wing dihedral is 1 degree. Not sure about the Four Star.
