Lunch box lunging forward

[Wee Chris 0]

Built my sons lunchbox and he’s been having great fun with it. 

Its now possessed!!

you turn it on & the controller drive forward or reverse but then it decides to lunge forward and sometimes drive without us touching controls. 

 

Any ideas how how to fix would be appreciated

Check the throttle trim on the transmitter - it's the most likely cause... (or a faulty ESC)

... and possibly low battery power in the transmitter or main vehicle battery?

Might be the trim on the throttle, you may have knocked it forward by mistake. My son does it.

try dialling the trim back a bit ?  Sliders on my stick control, a little dial on my wheel control

If all trimming doesn't work, try resetting your ESC.  

If that doesn't work, try exorcism.
