Afternoon all, I apologize for this being my first post bit I need a bit of help x3

Just got myself my first Nitro, this one hobbywarehouse.com.au/hsp-94862-08327-black-rc-monster-truck.html to be exact.

And well, its been fantastic! Heaps of fun, all that jazz.

Well, driving it just before. And the remote stopped responding, it went to full throttle and crashed into my shed x.x

Nothing broken, picked it up, checked it over, all good.
Started it back up, no problem
Then the moment I turned the steering a touch, it did the same. Remote lost control and the throttle jammed open. Failsafe failed and I shut it down by pinching the fuel line.

What the hell is going on! x.x

There are so many things that could be causing your issue. I would start with making sure your batteries are fully charged in the radio and as well as the ones that power the reciever. Hopefully you have another r/c that you can pull the servos and reciever out of and swap them in one by one until the problem has been alleviated. Also contact hobbywarehouse for a replacement.

Check to make sure you don't have any wires that are exposed and could be causing shorts, especially on the servos and receiver.
