Although my feedback will not help much, I have one that has been assembled, mounted a O.S. 91fx on it, but never has been flown. I built a G.P. Extra .60 and mounted the same engine on it, and was just more intrigued by it. If you have any interest in this one great, if not that's fine to. The only potential negative is, I cut the cowl to allow for the .91 to fit. This plane has the White with Dark blue trim.
Thanks and good luck!
P.S. I will say the W.Models P-51 I have flys great!
