Problematic electrickery... Help please!

[Jedward]

Ok I have a problem that has got me stumped

I have a C4.2 running the following setup;
SP Reventon S ESC
SP 13.5 v3,
SP sensor cable
nano tech saddles
Sanwa gemini trx and 451RX
The set-up is not new and has run before without issue.

I turn on the trx and rx, the car powers up I have steering but no throttle, nothing from the motor at all.

I have changed the saddles, Esc to another SP unit, the motor to another v3, tried a different sensor cable, tried different battery connectors, checked the servo leads are in the correct ports and pushed in and I still get the same problem?????????

So what is the problem, has to be something obvious right?

Have u rebound the transmitter to the speedo or changed receiver?

Yes tried both of these but still nothing from the motor...

The symptoms suggest esc but as you have changed it..? Only thing you haven't changed is transmitter.....must be something there, if not a binding problem must be esc setup...?

I've just been having the same symptoms as you with my new Absima CR4T radio, working fine then no motor, same things tried.
I ended up re-binding the receiver to a different profile (ie, the radio has 20 profiles, so I changed mine from No.6 to No.7) & it then worked, for some reason profile 6 kept 'un-binding' causing no throttle but I still had steering...

My son had this in the middle of a race meeting, no throttle but good steering. We just recalibrated the esc forward, neutral and reverse settings with the Tx and all was good again. Sure you have tried but worth a go if you have not.
