octavia 2002 1600cc when idling at 15000 rev it revs up by itself to 40000 rev anybody any idea why driving well

Hiya.

Boy, have you got problems!! Someone's stuck a real screamer of an engine in your motor!!

More seriously, your quoted idle speed is too high, should be about 800rpm, not 1_500 (hot engine). I'd suspect the idle speed controller, if the temperature gauge is reading correctly.

it must be a new unrestricted F1 engine look at the revs.

More seriously, IC engines for remote control cars and aircraft do run to those sorts of revs, but are sub-100cc 2-smokes.

RC car electric motors circa 40,000 revs+

RC car nitro (IC) engine circa 35,000 revs+
