He takes oldie but goody prop designs and makes carbon duplicates. He covers every common model engine size from .049 on up and several different applications. He is performing a very valuable service to some of us and I appreciate that fact. When you add up all his costs, he's not getting rich off of anyone.
I hope he is successful.
When it comes to Extreme Speed, getting the right prop is just as important as the plane and the engine.
There are examples where APC is just as good, but Steve's props can expand your possibilities.
It was his P-2 prop I did 200 with after trying every prop APC had to offer. As a matter of fact, APC does not offer any appropriate props for very many full wave piped, high timed set ups.
