    them things stall so many times you dont even need to.that is a reason i hate nitro stuff.but i dont really know i never asked anyone i raced that had nitro power because,like i said they stalled alot.i Do know that you can put your finger over the carb and that will definitly stop it.

    putting ur finger over the carb puts all kinda crap in ur engine, never do that. the most effective way of turning off an engine is to turn over ur car/truck and stick ur shoe on the flywheel causing it to stop. doing this is a fast way to turn off ur engine and fairly easy too. another easy, effective way is to put ur finger over the exhaust tip. no it is'nt hot! hope i could help out.

    bandit1......if you seal off the intake by putting your finger over the carb,where does the `all kinda crap` come into the engine from?
    if you put your finger over the carb nothing will get into it,including air.cutting off the air is what will stop it from running.
    correct me if im wrong.but i dout i am.

    i would say putting your finger over the exhuast would be the worst thing you could do.i would imagine you would get un burned fuel in it if you do it that way.im not an expert but i know how they run.

    Also the engine classification bugs me. Whats the diff between a 2.5 and 0.25? are they the same measurement unit? CC or CID?

    You definately dont put your finger on the carb... Picture this you have a nice realsized car and it is running (ie sucking air into the engine at high speeds) but you want to change the air filter so you start moving the cover and filter around and presto dirt and all kinds of crap finds its way around the seal on the air filter and into your engine wrecking it! bandit has the best ways in his post. pinching the line is ok but if your engine is hot already this will lean it out and make it even hotter and damage it.

    2.5 is refering to cubic centimeter. .15 is the same sized engine just measured in cubic inches. I suppose that bandits way is the most original i have hear but stopping the flywheel with a foriegn object is fine, but I plug the exhaust, Personally. However you will want to make sure that the piston is not at the top of its stroke (new engine only) because the engine cooling may cause it to sieze there. Cutting off the fuel is effective but does lean the motor out as rcosmax said. Never remove the air cleaner while the engine is running, never. The engine runs strictly on compression and the piston/sleeve is a pressure fit. Meaning that they are slightly cone shaped and at the top of the stroke that is when the piston/sleeve fit the tightest resulting in a good seal. Now take into account the effects of even on grain of sand on the cylinder wall and you have lost compression. And low compression is one reason that a nitro engine stalls all the time.

    im not a nitro guy but i still dont see how anything will get in to the engine if you cut off the intake by putting your figer or hand over the carb.i wouldnt take the filter off of it.
    however,rcosmax,talking about`realsized cars`i have adjusted air/fuel mixtures on carbs on small block Chevies with out the air filter on it.thats fine.

    I see a small tool on TV, it is like a plastic pen with one end that is to a point, like a Pencil, and they stick it in the exhaust

    if you do that, doesnt the unburned fuel that gets in the engine dry,harden up and lock up the piston and crank?im sure if it sits long enough with fuel in it that would happen but i guess you could free it up somehow.i dont know,i hate nitro.

    Yes, if you let the fuel sit it will build up varnish. But if you go through the after run procedures, like using after-run oil and cycling the engine you'll have no problems. The tool you speak of Davemc is made by Dubro called the KWIK STOP and is already available. Also they have some cool body clip retainers for those of you that have probs loosing them (T-Maxxers). I checked them out at the Chicago Hobby Expo. They worked so well we carry them at Radio Shack. The thing in the picture was in Chicago too and waay coo. There is even a spot for the electric starter for the Maxx that takes the place of the glow starter and it comes with the Kwik Stop.

    i dont like the way they sound.that anoying sound of them reving and they smell.
    people say nitro is faster than electric but that is not true.i can make as much horsepower with electric as any nitro engine.
