Default prop size

I have a Kadet senior w/surpass 70-Would like to fly slow-Will a 12x8 or 13x6 be a better choice?

Default RE: prop size

I run a 12 x 8 APC on a Sig Something Extra and it hauls butt, so I would go with the 13x6 wood prop at 1/4 throttle and she will creep. I have ran 14 -16 on the 91 surpass on a big trainer and it worked great. If you find a larger prop is to much of a load on the engine remember to use your left thumb, that will always let your plane fly slow.

It is turning 10,950 rpm with the 12x8 and 10,000 with the 13x6.
