Default Auto Shut-off

I noticed something with my TRX Pro.15 powered Nitro Stampede. When ever it flips or carwheels on the ground even if it get's back on all "4's" it shuts down. Why is this. I can't imagine that it is not getting fuel to the engine because sometimes it gets right back up. Sure EZ start starts it right up, but why does it do this?

Well my fuel line has a tiny tear, but we got new fuel lines for free and more body clips. Thanks Ralph at Larry's Hobbies!

air bubbles means airleak....check your lines for tears, etc....tank for cracks and if that dont work....then seal the carb neck and backplate with ultra gasket maker. The bubbles in the lines will lean you out!!

Try and pressure test the fuel tank by filling your sink with water, then submerge the fuel tank into the water and blow into the fuel line (one side blocked). If you see bubbles submerge try and see where they are coming from....if its a crack buy a new tank, if its the fuel cap seal, buy a new seal.

If the RC shuts down on you when it flips/upside down.....lenghten the fuel line coiling it but out of the way

My revo runs around four feet incase it flips.
It burns fuel fast and that's why it dies.

Well, I got a bigger fuel line. I don't jump it much. And it barley rolls so for the most part it isn't a problem, just annoying.

No, I have the stuff, but I am in trouble so not allowed to use RC stuff until Friday. So, no putting on the new fuel line till I can use RC again. Plus as I said above, it rarely flips because of how I drive it and if it wasn't for my new wheelie bar, it would be on its lid everytime I hit the throttle, it's insane!

One more question, if I get a new engine say a 2.5r engine, would it still be a single speed tranny, or can I upgrade it to 2 speed?
