How to stop a nitro engine
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.
