XRAY - Model racing cars

Hi guys,i have 4 xray cars,t3 12,nt1 wce,808e and rx8

I signed up to try to get help with my nt1 wce,i have the clutch set with minimum endplay approx 0.5 gap,the problem is when the engine is idling the clutch bell actually rotates backward (clockwise) the car works ok but i assume this put's a lot of unnecessary stress on parts as the clutch engages and the bell is suddenly spun the other way,also to note,there is a lot of micro vibration on the bell when idling.If i put my finger on the bell i can stop rotation but it starts again once i let go,any help would be most appreciated,thanks.The clutch on my old 2008 model did not do this with the same set up except shoe,maybe it's just because the bell is so light?,thanks.

dont worry about it as long as it goes the correct way when on power, its more likley just the vibration making it rorate and the easiest way is to spin the spur backwards on the one way

put al little grease on the thrust bearing, thats all.
