RE: LT 40 climbs forever!
Yesterday I took my LT-40 out for its flights # 5 and 6. For some reason the trainer box idle was a lot higher than it was the previous flights, and I had a hard time getting it to come down (but I landed it myself because I wanted the challenge). It currently has a fair amount of down elevator trim. Later with the low idle (we reset it mechanically) the instructor had me doing downwind landings, and I went from an average of 70% landings-per-approach to less than half. It just loves to float. My CG is towards the front of the range the instructions dictate. I don't really have to give it much down elevator on approach unless I'm coming in too high.
