The Main Problom was that the control surfaces were to big thus creating too much picth or roll force. The fix was easy, make the control surfaces smaller, Also originaly the plane could do aleron rolls really fast which a torpedo bomber (Especially the TBD Devastator) cant do unless you strapped a torpedo to the bottom of a Saber Jet XD, I also moved the Center of mass a little bit. Now I tested it pretty good but if you still find probloms of Stalling and Flat spin let me know and ill see what i can do From: Planeinator (PS: I added a torpedo, Be gentile with it on launch as it has a tendicy to blow off the fins when it hits the water)
