Default Strange problem

Ok so I was out at the local park last night having some fun bashing around a gravel track. Was going awesome, love drifting it sideways around 90 degree corners. got through half a tank or a bit more and nothing, no drive. Engine still running and responding, can rev it but wouldnt move.

So I turned it off and took it home, put it on bench, took cover off. Noticed a rock stuck in heat sinks on engine where glow plug is, its was jammed in there pretty good. Got it out with screw driver without damaging anything. Started it up again and running fine, responding to everything.

I cant work out how a rock in the heat sinks could prevent all drive???

Model is BS802T 1:8 .21 CXP

Sounds like the problems are unrelated. I've never heard of a rock in the cooling head causing a problem in the clutch/drive train.

gravel = bad for my buggy. But anyways. It was not the rock stuck in your heat sink. THEre was one in the wheel hub or flywheel hole (but that would make it stop). anyway it wasn't the one in the cooling head. Wheel hub man.

well you probly had a rock in the spur gear and it fell out before you got home....if it wasn't that then the rock in the head had some sort of mystical power that prevented anything around it to rotate....you should have kept it and took to your next race...it could be R/C Kriptonite LMAO!!!!!

Sounds like you might have had a stone stuck between the center gear and chassie. Once you shut it off the stone fell out.

Awesome, just what I thought, couldnt work out myself how something in the heat sink could have caused that. Oh well all working now thats all that matters.

Started it and ran it in garage last night, all seems to be fine. Most likeley the rock in centre gear.

Could it be the clutch with intermittent problem? I hope not ive only run 1.5 litres through it.
