That looks awesome!

after 3 grass crashes and repairs it just wanted to Yaw so I had to give some rudder on turns, it was so twitchy on landings and impossible to keep stable, do you think it was the flat clipped wing.

Beautiful, but I'll let someone with better experience suggest a motor for it.

While flat wings are twitchy I’d try adding more weight to the nose to move the CG a tiny bit more forward. Try taping a quarter to the underside of the nose I.e. throw money at it. If that works move your battery forward or use a heavier motor. This is where a kitchen scale comes in handy
