RE: 4-Balde props, pros and cons?
I have a SKybolt with a Saito 120 and had a APC 15-6 prop on it. The plane was really fast with this prop even at 1/2 throttle, I switch to a Graupner 14-7 3 blade prop to calm it down. I swear it's just as fast as before but now it pulls vertically like a tractor. The 3 blade really added to the look of the plane. If you want a 3 blade without losing performance try a Graupner.
