bgi,

Yes my saito is inverted without any problems as I mentioned above. My only problem was with the 12X8 apc that I was running. The plane hates to bleed speed with that prop and makes for fast landings. I recently switched to a 13X6 and now the plane slows down great. The only disadvantage of the 13X6 is that I lost a bit of top end speed. Welcome to a world of compromise.

Also I read a review of the aresti in RC modeler magazine, and the author mentioned that he found a degree or so of positive main wing incidence. I believe mine has the same problem, because once inverted it dives rather sharply until I can get on the down elevator. If anyone has suggestions of how to fix this I would greatly appreciate it. Great flying plane though!
