Fshawn, Well that sounds about right actually, I think the normal RPM for the 70 Magnum should be between 9,500 9,600. but I think its capable of the low 1,000's.

the OS 70 produces about 1,100 with 1.3 bhp and the 14x4 is what I used the most. but it 3d's much better with the 13x4 probably because of the weight. but I also used a 12x8 and it had some pretty good speed. but vertical has never been a problem with any of the props.

To the moon no prob. good luck and let us know what happened.
