Not sure, that is what I was asking. However; For testing and development, what we see here may not be the final design, including the shaft...
I started using these medium screw in base, DCv all voltage LED corn-row lamps. Wow...
Looks cool. Anything for 32v boats? 24v?
So that is a square and not a tapered shaft?? I thought that was a fancy PropSmith.
One more question to the OP; Are these DDEC engines?
ACv in, ACv out
Notice the angle the thingies are attached to the hub in post #1. Now check out this mount in the picture from post #61. Borrowing Carl's diagram...
