I am back building a 1/4 scale P-38 (156" wingspan 30" root cord)

Thanks, it flys very scale with long take-offs but once it is up on step it flies great. It is definitely not capable of anything approaching 3D, which is exactly what I wanted. It does loops, ...

RE: 1/4 scale P 51 Mustang

1/4 scale is definitely possible, but I agree with the prior post that time, planning, research, and money (oh, did I say money) are critical.
