ABC props

[Marc Paulais]

Hello,

I'm looking for some information (pitch and diameter) on the M-90 and M-91 props from ABC. The only indications I can get is that they are "similar" with X665 and X467, respectively.

How "similar" are they?

For information, I am considering trying them on a 47" Seaducer with a CMB 91RS (20% nitro).

Thanks

Marc

Marc,

Here's the numbers for the M-90:63.22mm @3.75" of pitch,w/6.00" to 6.43" of cup

@ .7 radi on the trailing edge. And the M-91:64.39mm @3.91" of pitch,w/5.63" of

cup @ .7 radi on the trailing edge. I just finished a set of each. Note: You will

usually lose .30mm when you sharpen and balance a propeller,so the actual

numbers will reduce just a little. They are a hardened propeller from ABC.

Good 90 motor propellers for a mono hull. You may want to try a ABC 2514 or

2614 also.

Good Luck Testing,

Mark Sholund

Mark,

I thought the M-90 had more pitch that the M-91.
