I agree with the suggestions to dump the .46LA. I bought one on an impulse and it is indeed a dog. I put it in a SIG MidStar and getting it off the ground generally required a brisk head wind and a generous bump in the runway. On the other hand, the .46 AX is everything the .46 LA isn't. I have a couple of them and put one in a SIG LT-40 which I use to train new members. Plenty of power, wonderful range. Worth every penny. By the way, the LT-40 is one wonderful airplane. Many members of our club have learned to fly with one, and and in addition to flying well, it builds well too.

Good luck to you.
