Stuck on High Revs, only when engine is running

[Simzter]

Hey,

I bought a 2nd hand Savage XL - it's a Big Block 5.9 engine.

I took it to have it tuned by an RC Shop - and all was well.

I did a bit of a front flip in it (accidental, but if anything the front right wheel took the brunt of it)

This wasn't at a massively high speed - and the car landed on its wheels and I thought nothing of it - given what I've seen the XL do on YouTube.

About 5 mins later - the car just took off - at full revs - breaks having no effect whatsoever.

I put the car on a block, and the same happened again - as soon as revs were applied. Oddly, the wheels twitched as if being moved by servos.

When switched off - the servos function normally, trigger opens the carb, brake closes the carb fully. There is also a spring attached to pull the carb shut.

This problem only happens when the engine is running..

Anyone any ideas?

Batteries are fully charged.

Check to see if your radio is zeroed out, dials at neutral position.

check all of your servo wires for a pinched or frayed wire thats usually what causes glitches like that

Also check for any loose parts vibrating metal on metal.
