My tiger wants to roll into inverted. I was trying them at a slower speed but it did not have the rudder for it. I finally just dropped the hammer 3 high and gave it a shot. It will climb very slowly with the 11x7 I just got about a gallon through the engine so I decided to change props and run it fully tuned with the diff prop. It will do them all day long now. Again at warp speed.

It was not the plane that could not do them it was the pilot. usually is .....

Note: the 10x7 is on my P-51 this one I went to 11x7.
