Carisma GT14B cut out problem

[Wadep]

Hi guys
I have been encountering issue with a new Gt14b rtr which has all at my local club scratching their heads.

When the car is driven round the track it manages half a lap then cuts out, in order to restart it the esc is turned of then on and it goes for another half lap and so on. All wires have been wiggled battery checked and binding of the radio checked but to no avail .

Here is the mad bit if the car is driven up and down in the outside corridor it's fine , it's been sent back to cml who have not been able to replicate the fault either.
A number of our club driver are cml sponsored and have never seen anything so frustrating happen.

Has anyone on this forum had a similar issue ?????

Any suggestions ideas welcome !!!
Thanks
