Here's mine post crash damage. Broken control horn and prop. Was doing an inverted pass about waist high, got to the edge of the field and wham, it was just slammed into the ground. Got a post "crash" comment of, yeah, when the wind is from that direction it gets turbulent over there. Oh well, it's already repaired. Only one other epp wing out today, we did combat, and I won by default 2 times, he crashed both times when we got close to the ground. This thing is sparking some interest, may need to get more.
Watching Lee's videos, and running about 100/60 differential right now, it almost rolls straight, may need to add some more deflection. What are you running for differential in the elevons? I'll try 50% down tomorrow, and see which way it takes me. Oh what prop are you running in that "power sloping" video?
