2.4 GHz loosing signal

[Jamie B4]

Seem to have a problem in that my car is suffering from a loss of signal on the futaba fasst system. Any ides what i can do or try.

Seems to be ok then the race startsand the car gives the impression that the signal has failed and stops / starts. Then a marshall will switch it off and on and it seems fine then.

Any chance that it is the receiver etc?

Have 2 cars 2 & 4WD and both suffer from the same thing so dont think its the receivers - more the module on the tranny.

Thanks in advance
