It was also 76” vs a data plate calling
for 74”. With that data incorrect, it could have been a totally wrong prop and
may not have even been 88” pitch.
What is Sam going to have Catto do to the
prop?

Prop area Comparison
Just doing a rough back of the envelope calculation
comparing Sam Hodges prop (8" cord) to my prop (5 1/2" cord)
and assuming the two props blade profiles were similar, Sam's prop would have
approx 45% more prop area trying to push the air back than my prop. Small
wonder his engine was groaning trying to spin it up to 6000 rpm.
