It's called a spun hub TP.....it's when the rubber hub in the prop loses it's grip on the metal prop hub. High rev and slowing or no pick up in forward motion is classic spun hub.


If you want to verify the spun hub, draw a reference line from the rubber hub out to the metal hub of the prop. Take the rig out and let the problem occur. After, remove the prop and check the reference line. If the line on the rubber is not matched up to the line on the metal, hub is spun. Any good prop shop can rehub it for you.
