Dennis,

It was a strange problem. The way the top keys to the bottom there is no way I was doing something wrong. In fact, I had somebody else come over and look at it and he had the same problem. I asked Sig if it's possible for a sheet to slip as it goes through the laser, and they said no.

More detail: If any of the notches were matched up, then the notches in front of the matching notch were off in one direction and the notches behind were off in the other. Don't know if that makes sense or not.

Said another way. Let's say I matched a notch at mid-length. The notches in front of that notch were behind the matching notches and the notches behind the notch that matched were ahead of their matches.

Another guy in our club has built the Cub too and with the Norvel it flew way too fast. That's why I knew the power I was provided for this model was too much. I replaced an OS .15 CV-A with the same electric motor and the electric is MORE powerful than the CV-A.

So in essence he's put the power of a racing .15 on this airplane. The wings won't be able to handle it if he pulls back the stick too abruptly. But it's his plane and I did want he wants. All I can say is I've warned him and it's his responsibility. As long as he flies the plane as intended it will be fine. Use the power to go straight up and then pull back to no more than 1/3 throttle for level flight.

PS. I wouldn't have sold the plane for $100 unless it didn't fly that great. It looks like another of those kinds of planes that has a lot of bang for the buck.
