Yes, same ol' Lama 4 problem. I had my old Lama 4 flying great with about 6 1/2" of separation between the flybar weights. I've been there and now all the way down to 4" of separation and I still have porpoising. It's ridiculous already. This A-300/ Lama 4 is very disappointing. I can't even get any decent flights out of it and I've been at it since I got it in December.
