The 11-7 1/2 MAS prop is the best prop I've found for the K&B .61's
after over 30 years of flying them.

For some reason, most people think the APC props are great, much better
than the Master Airscrews....I don't know why....[sm=stupid.gif]

I just gave away all my APC props, about 15 or so.

FBD.
