How do you stop your engine??
I would like to see how the majority of you stop your engines, and let's here your opinions on why you do it your way.

RE: How do you stop your engine??
There are 4 ways to stop an engine.
1. Pinch the fuel line.
2. Cover the carb or airfilter.
3. Plug the exhaust.
4. Stop the flywheel.
1 - This is a popular method but not recommended. When using this method, you are starving the engine of fuel, which causes it to stop running. The problem is that you are also starving it of lubrication and causing it to run lean before quitting. This is hard on the engine, as it creates wear and tear prior to the stall. Other than number 4, this is the least stressful way to stop an engine.
2 - This method stops the engine by eliminating air intake. This method is also not good for the engine as it floods the engine out until it stalls. By doing this, you create massive amounts of compression in the engine and can blow seals, gaskets, or bend the connecting rod.
3 - This method stops the engine the by preventing exhaust from exiting the combustion chamber, essentially forcing the engine to quit running due to an increase in compression so high, that the rotating mass of the piston can no longer overcome it. Needless to say, this is terrible on an engine, and the worst way to stop it.
4 - Stopping the engine this way is the best method. It quits running to to the load increasing beyond the capacity of the engine. While slightly hard on the internals, it is no where near as damaging as the previous three ways.
Obviously, I use method number 4. If you have a Tmaxx or other vehicle that doesn't have an accessible carb, then the first way is the next best.

5. Crash it into a tree
6. Crash it into a mailbox
7. Make it blow up
Or if u are like me, if i pull all the way back on my trigger (reverse wise) the truck shuts off...i like this way.

8. Flip it upside down (nitro)
9. Use the kill switch (large scale gas/oil mix cars)

I don't have a vehicle, but can't you set throttle trim to maximim negative? Like killing the engine on an airplane? Essentially you are just starving the engine out of air AND fuel at the same time...
Is it not a way to stop the engine?

RE: How do you stop your engine??
the problem with that is it would kill the engine everytime you hit the brakes because of how the linkage is setup (applying the brakes pulls the throttle linkage back past the idle position)
where is the "jump it into a large body of water" option??? that always works for me

RE: How do you stop your engine??
yea stoping the flywheel...hmm what would you use besides your shoes... a pink eraser and wedge it between the chassis and flywheel or stickk or whatever. i dont really have a problem stopin it by pinchin the fuel line..and when covering the carb it shuts the engine almost instantly and i dont get how that would flood the engine... not going against you guys but i juss dont see it really damaging(sp) the engine

RE: How do you stop your engine??
I run my idle pretty low as do other people. I've seen people land land on the pipes on the track and flame out. It really doesn't take a lot to stop the flywheel at idle. The end of a screw driver, an old igniter, stick of wood or even just the tip of your shoe should stop the engine pretty easy.
I personally think stopping the flywheel is the best way. Pinching the fuel line leans the engine. Plugging the carb opening is kind of hard when you've zip-tied the air filter on with all your might to prevent air leaks. Plugging the stinger will leave you will circle shaped burns on your fingers and you don't always have a rag or a pair of gloves to use.
This is also the way all the people at our track stop their engines.

RE: How do you stop your engine??
Well heres a question...
What is the least destructive way to stop an engine at full throttle when a runaway happends? This has happend to my friend a few times when he was first starting out and he would be able to catch his car but with the body on and all, he had to act fast so he plugged the stinger with his finger. I know any way would be bad but whats the best way (not including plugging the air filter)?

If the car is properly equipped with a failsafe and a throttle return spring, you shouldn't have runaway's. But in any case, the best way to stop the engine, even at high RPM is to just lightly tap the flywheel with the bottom of your shoe. Again, in the case of a runaway, stopping the engine is paramount - so any method is better than no method. This is just the way which is least likely to cause damage.

Eric - If using standard servos, there is a strong possibilty that you will strip out the gears in the servo by doing that. If using hit-torque servos, you won't be able to move them by hand if the TX is on.

I would also like to add that in that case, the engine is at full throttle with the wheels off the ground so if he took the body off then shut off the TX or RX the engine would probably break. I'm happy to tell you he invested in a failsafe.

RE: How do you stop your engine??
Hit brakes, it idles very low, then touch the flywheel with your finger. It doesn't hurt, the torque it's producing at sub 3k rpms is minimal. At first I was afraid to touch it, so I used a stick or the edge of the track barrier. I tried it once, works fine, and is the least harmful to the engine. Another option, should you wuss out, unscrew the plug till it looses compretion and quits...

Yea, but about the throttle trim, once you set it to full negative, the engine quits, right, but next time u use it you push it back up to normal
Then it wouldnt die on brakes
Not arguing, i just dont get how normally running you hit the brakes and the engine quits with your throttle trim at normal
To me I believe if this was possible it would be the BEST way to stop them expensive engines.

RE: How do you stop your engine??
yub - when the brakes apply, they also close the carb as far as it will go. If you set it up as you say, then when the brakes are applies, the carb would close all the way and shut the engine down. Try it if you want to see how this works.
