Eric,
I agree with Patrick ... incredibly useful.
I've asked a follow-up question elsewhere, but will ask it here too, where it seems more to the point of the post topic.
What is the reduction ratio of your transmission?? [At least, in your photos, it appears that you have some sort of transmission or reduction between the motor and prop shaft.]
I've also already noted elsewhere that you're running a 4-blade wheel of 13" x 15.5" dimensions.? [Also a very helpful detail for verifying 3rd party prop estimating tables.]
Thanks in advance for the additional detail ... I would just like to work out the prop shaft speed to go with prop information.
