Well I just picked up the YS. Looks sweet, I was thinking about getting a different airframe to put it in, but after thinking about how much fun I have had over the last 100 flights I going to have to order a new fuse. I don't think I have another airplane that I push as hard as this one. I geuss I have adopted the I don't care if I wreck it attitude and it has made it much more enjoyable. The only thing I will have to do on the new one is figure out the mixes for knife edge.
