I just bought a Red Cat Gen 8 Scout II and it ran perfectly the first two times I used it. Then I went and started installing lights. Now I can’t get the darn thing to go. I can steer but no acceleration. To trouble shoot I swapped the channels and when hooked to the steering channel I can accelerate but no steering on the throttle channel. I even tried installing a new receiver thin ink I had a bad channel and same results. Can someone help me.

unhook lights.. they are using to much of the esc bec to allow esc to run hookup lights on a separate battery.or you install a ubec that will handle the load your putting the esc under. you will have to pull center wire on esc rx plug heatshrink it and slide little lock on rx plug to slide it out.id get a 15 amp ubec

Thanks for the advice, the first thing I did when I realized I didn’t have throttle is remove the lights. But it still will not operate. The esc is quick flashing red and according to the manual, it means the trim needs adjustment, but that doesn’t help, and I made sure I had a fully charged battery installed. I filed a warranty form with red cat, to get the esc replaced. Thanks for your response.

I have the same problem

After installing lights my steering isn’t working and throttle is stuck on full not sure what to do now i might change everything esc transmitter and receiver all I wanted is my lights to go back on
I know my way around my rc everything is done correctly but it is now giving me problems

It sounds like the lights are drawing more power than the bec can handle. Does everything work if you disconnect the lights again?
Nothing works there’s no power to the Light kit it’s running the original wire harness no extra wires just the ones that came with the crawler

Hmmmm, try disconnecting things one at a time, servo, etc. if that doesn't get any kind of response you may have toasted the esc.
The esc is blinking it’s seems to be working? But no response to the controls
If that’s the problem should I go brushless and what system should I use I wanna go brushless and different shocks

buy a big enough ubec.. that can handle all you have added,, then disconnect center esc to rx wire. and install ubec. easy fix, going brushless will not fix issue,

If you are thinking about replacing the system you might look into something like this.

Update I found the problem I think it seems to be working better than before I switched all the battery’s and. Unplugged everything and plugged it all back and it works I guess but the lights are not working
