Pe'

I have run 16x12 APC and 17x10N APC on my pattern planes withe the S.T.2300 with good results in the 84-8600 rpm range, however that is with a semi-tuned pipe setup too. What nitro content do you use? I may be propping up to much. I just thought the wider blade props would work better in this type of airplane (25% Cap 232).
