Regarding APC, e Balance

It will probably end up around two pounds, so saving some battery weight by driving the amp draw down and efficiency up is probably a win.

But I'll have to go 10x4.7 or maybe 10x7. I've never been able to get an APC "e" prop to balance. What's the trick?

I did get some 22awg from HSC (finally got some wire stock in) so I'll be able to start with a simple reference wind. Wonder how it will run with 18 turns on each tooth...?

I have found the hole to be crooked and way off on some , I have not checked for different blade thickness though , I just put the prop up on a milling machine and put in an enlarged hole in,,, on centre , then just make a bush to make the hole smaller , lot of work ,
