For those who are planning to use a APS 63100, I created a Mount for Gong Mast.
God it is huge bipale best ratio in air maybe in water but need good balance…just the props look dangerous…
What dimensions is the prop?
It is 12 inch pitch. The diameter must be adjusted. Right now I cut it down to 9,4 inch
But I think this is still too big.
Looks really good, nice streamlining on the blade hub! Did you fill the magnet gaps?
Thanks. I am waiting for the ceramic bearings, then I will take the motor apart and fill the gaps. Did you do that already? Any hints?
There are several ways to fill the gaps, i used centrifugal casting and epoxy. You need a rubber ring inside the bells end and a printed ring at the open end glued with tape. I think it is the best result, but its not easy and dangerous because you are not allowed to stop the turning while curing. You also need to lathe the abandon epoxy. Look for direct drive direct cooling to get detailed info with pictures.
Just to notice that @Flying_Rodeo has chosen the opposite strategy to decrease vibrations in water: hub diameter enlargement to let the water flow self adapt at any speed. We should have some feedbacks from users having ordered the 65150 prop very soon.
I’ve already left a review of that prop in the motor thread…
seems nobody read it
