thanks steve , Off course I will replace with the novak one , but I wont get it before a least a week maybe more. I was just wondering if maybe the other one can do the trick for a week or 2 , the time I receive the novak one. Its been 2 week since my esc broke and I see the end of the season comming very fast here in the north, having to wait again a week or 2 is killing me, plus I have to test this used gtx to make sure its work fine.

But if its critical and can damage the ESC I guess I will wait.

The seller test it with the kink ,flat spoted cap and said its work , but I just dont want to take the chance to run it with that cap
