I have flown the Corsair, The P-47 and now have a zero. I found the JK Aerotech kits easy to build and repair. My Corsair has finally been retired after 3 years and many flights. The Guys at JK were excellent with advice and product support. I flew many RCCA events in Michigan and had a ball. I now just fly for fun locally, but, my zero will turn almost in it's own length and is a hoot to fly. The P-47 is bigger and not as fast but flies equally as well and can be made to look really great as a sport flier. Just my .02 cents worth.
