I've flown the 109 twice more with the NGH 35. Got her tuned. Tached 7,550 rpm now it's leaned out and breaking in. Plenty of power now. Flying really good. However, on first take off I over corrected and she went right and had to chop throttle and try again. I'm thinking of getting a gyro to use with the rudder to help this problem. Landing also can be a problem. Really hard to land on the mains without bouncing (with the gear moved forward to prevent nose overs) trying to land 3 pt is as a problem as she doesn't want to land in the three point attitude, then gets too slow and a wing drops. Maybe I'll try less flaps. Anyway the engine swap is a success and I'm happy with the performance of the plane in the air. Now if I can just learn to take off and land.
