I just finished my GWS Zero today and went for a flight. The plane climbed when tossed and then rolled inverted left and crashed into the ground, I did this twice and decided to call it a day while the plane was still flyable. Any thoughts on the model. I have added some weight to the nose to get the CG behind the spare, but really not sure what the problem is. This is my second warbird, my GWS P51 has some issues = so I got the Zero since I heard is was a bit easier to fly.

Thanks!!
