New prop

Re: New prop

Our old L-4 (c-85) gained 10mph and a few hundred fpm climb once the 1b90 was installed. I think the sensenich was a climb prop and the 1b90 was a 72/45. Wood looks nice, but it's not as efficient as metal.

Re: New prop

I'm turning a metal Sensenich 74CK-2-38 on a A-75 BC12-D and I'm satisfied with its all around performance.

The other BC12-D on the field with a A-65, is turning a wood prop and in my opinion, is much slower on take off and on cruise. this could be attributable to the A-65 Vs A-75.

Hope this helps
