Newbie with a problem accelerating

[b20wht]

Hi Im new to this hobbie and just bought a cougar sv with lrp esc and motor. Finally got the radio gear and got it up and running today. Problem I have is that when I push the stick all the way forward quickly the car just kinda of stutters until you release the stick a bit and then it gos! Its fine if you push it forward slowly just not when doing it fast. Im sure its probably something I havent set up properly but can anyone give me an idea what the problem could be please?

The tansmitter is a Etronix Pulse 2.4g. Do I need to set something up on here maybe?

What kind of batteries are you using?
Just a wild guess, but it sounds like you're using "NiMH' batteries (and not LiPOs) - and if that's the case that's your problem.
If you're using LiPO batts, then it could be that you need to go through the "set-up instructions" of your ESC.

Yeah Im using lipo battery. Will read through the set up for the esc and see what happens thanks.

OK - then, did you "calibrate" the ESC to the radio after installing the new BL system?
If not, it definitely needs to be "set-up" following the included instructions that came with the ESC.

Otherwise, only other thing I would potentially question is your wiring - bad soldering, loose/worn connectors, or what the call "a pile of spaghetti" wiring with a jumbled pile of wires running everywhere and cris-crossing each other haphazardly.

Ok just set up the esc and no different! any other ideas?

Could be that the speedo needs to setup for lipo (not the nimh setting).

Other than that, try a new sensor cable

Definately sounds like a sensor based issue. Hopefully just the cable that needs replacing
