Get an Xtreme Comp Astral XX its like $2500 and built out of this cool TAVS stuff. You might have heard it was made famous by this company in China. They built the model that won the US NATS in 2004

Just in jest. I have an Impact too. I won't build it. Its a pile and not straight. I guess at my age $800 would have bought a wild night at a Vegas Strip club. Instead I have a right wing that is twisted a full degree from root to tip. The fuse is "bent" laying a straight edge down the side, right side fits the straight edge perfectly. But the left side is low in the middle and I mean low its about 1/4" low.

Then we can talk about the fin and built in right rudder/thrust compensator. Or the weight of the wing panels.

I'm not alone here and hate talk poorly about a product. You pays your money and you takes your chances! I won't go bargain basement again. My motor, servos, radio, and my time Why would I waste all this to fly a pile of crap than could cost me even more than it already has.
