Maiden flight of my used P 51 Mustang.

I'm not sure who makes this plane. I was told it could be a Dynum.
Any way, it is a blast to fly but seems to want to stall pretty easy on turns. I Need More Power Scotty!!! I don't want to have to fly at full throttle my whole flight . Since this flight, I now have retracts and the rudder reacquired. Looking forward to another test flight.
