RE: O.S. VS. SAITO???
lol the OS puts out more power come on now. the only the OS will spin a prop faster is on 0 or 5% nitro thats it. run both on 15% and then tell me lol which one spins the same prop faster.
I dont know why saito makes so many different sizes when most are of the same size range. the 65,82, 91s, 100,115 and 125 are all about the same size with only weight being different. of those i would only run the 125. I have all of them except the 100. The 150, 180 and 220 same thing. I do have the little 40 too and i get 11,600 on a zinger 12x4
