Thanks for the info guys. I was a little undecided about the CS but ended up going for it. Kind of liked the picked out peseta and yes those cylinders do look nice. For a prop I have a mix to try of Mejzlik, Xoar, and Falcon. Sizes 30x12 and 13, 31x12, and some 32x10's. Engine is going into a Pilot 42% Edge 540 in the Matthais Dolderer GSHOCK scheme from the Red Bull races. They charge a tidy sum for these engines, but in the long run I think it will be worth it.
