RE: TF P-47 engine
Birdog put as much motor as you can stuff in it. I fly mine with an ys 1.20nc fourstroke and it just right. I also fly the 190d-9 with a YS 1.20fz fourstroke and it like it also. Both planes weight around 12lbs fully decked out.[8D]
Kirk are you flying the 1/5 scale P-47 with the ZDZ in it?
