LOL if CEN wont warranty that $6-$15 part, I will!! some people get so upset about very inexpensive things. All rc parts are subject to premature failure, no matter what brand!! You wil spend 4-10 times as much in time and shipping that engine back to and forth to CEN to get a commonly worn part that my or may not still be under warranty. I mean, Geeze if you dont like tearing your rig apart to repair it then you should have not got yourself a nitro vehicle.

No need to get upset about a OWB going bad on a Hobby Grade Nitro Monster Truck!! You WILLbe replacing many more during the life of your rig. Besides CEN did ot manufacture the Drawn Cup Roller Clutch(OWB), another manufacturer did, and there is now way for CEN to know which OWB out of thousands will fail!So Call it luck of the draw that you got a faulty unit.

The point here is, it will cost you and CEN less in time and money, to just order the OWB and replace it yourself. And consider the OWB a consumable item on any nitro rig, let alone one that has so much compression!!

Fix it and then enjoy it again!!

Hope this helps.
