SIG stopped making the previous run of 4 Stars, probably because of the poor construction of the wing, the rest of the plane was well made so I was surprised to find the wing go BOOM. I know where I can get 2 4*40's still, a Red and Yellow one. I was tempted but after the first one, I just know that a 4*40 with a 91 would not last long. It would be fast, it would be strong in the vertical, but it would also kit itself in flight.
I was pointed to the Vanessa rig for balancing, and balanced my P-51 yesterday, and it was so easy, so going to rebalance my 120 since I feel it is still too nose heavy, and the GP balancer is a PITA to use. Not going to touch my LT-40, its perfect right where it is, in fact it has NO dead weight in it.
