Default Need 8" or 9" props with 8 to 10" pitches.

Have a twin engine plane with geared down motors runing about 7,000 rpms Would like very wide blades for running on 1 engine. 2 to 4 blades are O K.


Appears APC PROPS has dropped a lot of them on the old 2009 posted web site.

I need THRUST to fly on 1 engine. I can gear up or down to get a 2.5 to 3 pound plane to fly on 1 engine.


Thanks

Electric? The 8x8, 9x9, and 10x10 e-props are off the shelf at my LHS, and listed on APC's site.

Glow? These are all on APC's website as well:

8x8
9x8
9x9
9x10

The latest version of the website is confusing, I began to wonder if you might have missed the other pages after I had to hunt around for each prop. It think it would be difficult to design a worse website. After all, why put the 9-10 and 9-9 together when they could be at opposite ends of the list. Buy hey, they make great props!

I just figured out why the prop list is a mess - it is the way the rows are sorted by whatever software they used. 10.5 comes before 10, and 10 inch pitch props show up at the beginning of the list because the first digit is 1. Looks like an alphabetic sort versus numerical by diameter first then pitch second.
