Well don't be too surprised. Cambo, and a lot of other folks are flying the GP CAP 232 with a 79" wingspan and a DA or DL-50 in them at 13.5 pounds AUW. Again, a 40cc plane but it flies great with the 50 in it. It's just going to depend on the plane and how it's built. My son bought a Pitts S2B from Cermark and it was a really well made ARF. Odds are this one will be too. Just doesn't pay a dealer to put crap out there with RCU around. Everybody in the world finds out the next day and they can't get rid of the things. I love it!!!!
