LRP X12 7.5 SENSOR PROBLEM

[WHITTLER555]

Hi, please could someone suggest an answer to my problem?

I have an LRP X12 7.5T motor bought off a known driver. I ran the motor in my 2WD for four races and then as I applied full power the motor would start making the car go backwards!

The driver said he would fix it as I had only just bought it and duly fitted new sensors?

The motor has run five qualifiers today at Southport in a 4WD car and at the start of the final it has done exactly the same?

Question is, can the sensors be bought separately as I don't have the original receipt available to send it to SMD.

Has anyone else had a similar sensor failure with the X12 series motors?

Thanks

DW
