Hi Billy:

Our current numbers are different on the 14x7e prop. I'm only drawing 44 amps or so at full throttle. We're running different batteries 4400mah vs 4900 mah but I don't think that would be the cause.

On my 1st 4120-18 I was drawing about 52 amps with this setup. I started noticeing a problem with the motor, seemed like something was sticking when I turned the motor by hand.

I took the motor back to the hobby shop who in turn sent it back to Hobby Lobby. There reply was that it seemed have gotten hot as the magnets were discolored.

Hobby Lobby sent me a brand new motor and now my current draw is quite a bit less (now 44 amps) but I'm getting the same end results with the 14x7e prop.

Rich
