There are many ways to stop a nitro engine. Here’s the pros and cons of each methods. Personally, I prefer to clog the tuned pipe, however if my engine is out of control I pinch the fuel line because is more accessible even if the body still on the vehicle. If the flywheel can be reached easily, like on my RC10GT2, I will use my shoe to block the flywheel.
I’m not a big fan of removing the air filter to block the carb intake with my finger to stop my engine because my air filter is secured to the carb with zip tie making if more difficult to remove.

NEVER USE YOUR FINGERS
TO STOP THE FLYWHEEL

|Clog the tuned pipe’s stinger||Your engine will be primed for the next start||Can flood your engineTuned pipe may burn your fingers
Will not stop the engine if the engine revs out of control
|Block the carb intake||Immediately stops the engine even if the engine revs out of controlEngine stops because it lacks air, this is safe for your engine||Not easily accessibleMust remove air filter every time
Can be dangerous due to the few rotating parts near the carb
Dirt can enter the carb
|Pinch the fuel line||If this is the last run, no fuel will remain in your engine and you can add few drops of after run oil||
Will lean the engine before it stops
Fuel line may be difficult to reach
Will take few seconds to stop the engine if the engine revs out of control
