HyTorq vs ACME props for 410DA
Pulled props and had them spec'd on a Hale MRI at Propulsion, Inc of Hudson, WI. (715)386-2547 www.propfix.com
Everything checked out fine, with the exception of the pitch on each was closer to 26p, than 25 as the props are stamped... :huh:
LH = 22"x25p - Actual pitch average of all blades is 25.791
RH = 22"x25p - Actual pitch average of all blades is 25.639
This might explain the slight run slow from 2800rpm WOT spec.
I am looking for a set of "spot on" 22"x25p props, if anyone knows of a pair for sale.
Another question - I have 3" of tunnel clearance around my OEM props. Is there any efficiency gained by running 24" diameter? Would you back off on pitch or run same?
