I need some help please.
Ive got a Tekin RS in my 22,and tonight at Silverstones fantastic new venue

i had an issue when i turned the car on for the first time. If i pushed the throttle to full to test, it would be fine for about 2 seconds then drop down to around half speed and the lights would also drop down to around half way. Now i had this before and i needed to rebind the speedo and the transmitter together, i tried to do this but it didn't like the full forward position, i waited until the racing had stopped and did it again and it all worked fine. I went out to race, come back in at the end and then to marshall, when i came back i tried the car and the same thing again.
Now 1 thing i did notice was when i pushed full throttle the bind light on the RX dimmed down until i let go. Im running a sanwa 2.4 system but i have the Ansmann RX in the car, ive run these for around year or so with no issues, do you think it could be that ?
It may have been a coincident, but one attemp i moved the sensor wire and it worked and another i just left it switched on and kept trying it and it worked.
Anyideas, i thinking of trying another RX first.
Cheers
Ross
