Terry,

Nice work!!!
How much rake angle did you mold into these beauties? 20*-degrees?
What did the final Leading Edge Pitch 30% up from the hub
measure out at after casting? Just curious how fast these blades are
going to go ? 63 mm correct ?

Thanks,

Thanks.

These were based off a 1667 which has about 17* of rake as far as I can tell. My previous props were 2170 based which has 12*. Will be interesting to see what the extra rake will do.

Average LE pitch at 75% for the first 15* of rotation is 7" or so. TE is 8". Yup, 63 mm.

3063?
