Thanks Marto. Im going to have to wait until next week to fly her with the new YS70. As I was breaking the engine in, The prop nut, prop and spinner decided to go flying without the plane attached. I had to order a new two piece nut nut assembly and it wont be here until weds. Diving while inverted seems to be as you said, an unfortunate characteristic of this plane. Makes it more difficult to perform those long slooow runs across the field. My TOC yak and edge 540t assume a level flight path while inverted. Even my old tower hobbies kaos flies straight and level inverted. I wish I had waited before buying this airframe, I would have bought the Mrs. Wind instead. This is the maiden if you have a minute. I only have maybe 6 total flights with it. I just wasnt happy with the motor and decided to not fly it again until I purchased the YS.
