help required please suspected radio gear problems

[sprout451]

hi all

Getting back into the rc racing again but having some problem with the car. The problem starts when i accelerate down the long straight at our club turn for the corner then the car stays flat out with the steering servo locked over to one side and the transmitter does nothing. The kit i'm using is a savox 1251 steering servo a code sport transmitter and receiver reedy 7000mah lipo batteries a lrp x20 stock spec motor and a core rc speed controller, speaking to one of the lads tonight he's suggested trying a receiver booster. just wondering if anyone else has experienced this before and what the cure is.

Any help greatly received.

Many thanks
