I fly a Katana T30 stuntplane, wingspan 85 inch. All my settings are set to 0 degrees. The plane flies well, but when I'am slowing down speed to get ready for landing my plane starts to go up ogf its own. I' always have to force it down. My center of gravity is OK.
Can I help it by using the ailerons as flaps (a little bit up or down)
I've already tried this at high altitude, either way my plane goes up.
Does anyone know how to solve this, I already have broken my landinggears three times because of it.
