If you don't do anything else to this plane, Beef up the landing gear. The first flight with my chippy ended with both wheel pants (& landing gear) sticking up thru the wing covering! Learned the hard way to reineforce the landing gear blocks. By the way, like every one else said: It is one sweet flying plane! I have a Y.S. 61LS with a 13-8 apc. Plenty of power for all maneuvers.
It is neat to go into the EAA Oshkosh Museum and see the original hanging upside down in the aerobatic section.
