XRAY - Model racing cars

hello,
when i am running the t2 and turn the steering it starts to make a bad noise and the belt moves about, as if it was catching on something. but it only does it when i have the spool or the solid one way in, it does not do it when the standard one way is in.

can you help please.

thanks martin

That is quite normal and nothing to be worried about. You won't notice anything on the track.

Not quite true Tony, running the car on max flex (with all screws out) you could hear the belt rubbing and after a few laps the front belt flipped over!! this also happened with another car on the same setup. now only run with all the (4)screws in the top deck.
