Help please R1 pro

[pb1]

Hi all,
I Have a problem with a tekin r1pro?
My son is running a Losi xcelorin sensored motor,
When he starts off racing there seems to be a delay from the import to the hand set which delays the car from moving. If he crashes the same thing happens ! the marshalls will turn the car back on it's wheels then,5-6sec later the car will move.

The reciever is ok as no problem in his other car running a novak motor and ESC.

Hope some can help

thanks Paul
