Just wanted to let you know i put the OS1.60 in my Hangar 9 P-47 60 scale and it flys great.
Had to move the battery behind the CG from where it was previously in front of the CG slightly.
Flys and lands great.
I did add an additional 3/16 to the firewall and added gussets behind the firewall that tied into the firewall and fuselage.
I didnt fiberglass the two wing halves together yet, but I will do that soon.
That was with an APC 15/13 prop..
