My previous post:

I have two edf55 units that i have 20-30-3500 ammo BLmotors for. The shafts to do not have a D cut in them, they are round. The impeller hubs that came with the fan units have to set screws 180 degrees apart from each other. I cannot for the life of meget the impeller hub (or prop adapter, whatever its called) centered on the shaft. Can anyone help??? Please, this is driving me insane!!!

Update:

Perhaps I should have used my caliper immediately rather than trusting the EDF unit specs! The specs stated the hub was a 2mm hub. However, in a moment of clarity, I was just fiddling around keeping my hands busy and stuck the hub on a small screwdriver i have on my bench. VOILA!a perfect fit!! LOL and I grab my caliper and sure enough, the screwdriver has a diameter of 3MM!! Sorry, for littering this forum that is a wealth of knowledge with my idiotic mistake!!

I assure you, I am not as dumb as I look! lol
