Just received my UCD today. I will be running it with the O.S. 61SF-P (pumped) motor. The instructions say nothing over 6 inches of pitch. All the props I have for the engine that O.S. reccommended are in the 7-9 pitch range, 11 and 12 in diameter. These worked fine on my other plane, but the UCD says no more than 6 on pitch. I did buy a 3 blade 11X7 and 12X6 prop for it because of never flown a tail dragger before, and figured this was safe too keep the prop away from the ground while I learned. Any suggestions would be helpful.

Thanks
