Hello there,

nitrosportsandrunner

when you say you only just got it.....have you done the motor breakin process?

nitro motors need to be broken in. this is done buy running them very rich to start with, and tank after tank (usually 4-5 tanks) leaning out the fuel mixture and thus slowly raising the motor temps with each tank of fuel.

If you are trying to drive the car without having done this, then it wont like you very much[&o]

The issues you are describing generally sound as tho its setup very lean (not enough fuel)

When you say it idles for a few minutes and then stops running, does the idle get higher before it dies?

Do you have a temp gun? These are very helpful for tuning nitro motors. They can tell you (in general) if the motor is rich (will not be warm enough) or lean (will run to hot) They can be found for $20-$25 at hobby shops and on ebay.

You may also want to install a new glow plug. Then can get worn, so that the motor will still start but not run right. sometimes a bad carb setting will cause glow plugs to go bad, even tho they have not been used much.

so, get temp gun, new glow plug and reset the needles to factory. If you still have issues, you will want to check all fuel lines, tank, tank cap seal, muffler seal (where it meets motor) for any air leaks.

Sounds too rich, you can either raise the idle up a little or lean the low needle in a 1/4 turn and try it out, also make sure you keep the igniter on and give it some thottle while off the ground to clear the engine of built up fuel.

Same problem here. Brand new. First tank idle went ok. Second tank cant get it to move. If i hold it off the ground at part throttle it runs for 3 seconds and shuts down instantly. Tried needle adjustments and same thing. If i leave ignitor on it powers right up to wot. About how many turns should lsn be.

I agree with the other replies about break-in and too rich/too lean issues.

One other thing to check is for a broken spring in the clutch......a broken spring will make clutch engagement eratic, and kill the motor. I had this problem on my Caldera 3.0.

i read the post on pinching the fuel line taking 3-5 seconds to kill the engine. my lsn has to be at 4.5 for that to happen . does that seem right. truck will not stay on still though

Had the same problems on a brand new Redcat Racing Caldera 3.0. Just could not it to stay running unless the igniter was on the glow plug. Had to send it out to Redcat for them to check out, and they indicated that it was the glow plug had gone bad. They replaced it and made adjustments. Got it back the other day, and had some problems starting it (which caused the pull starter to fail), but eventually got it working. Seems to run well, unfortunately, I've now got other issues (no replacement starters in stock, and a broken spur gear due to trying another brand starter).. My friend said "welcome to the world of RC cars/trucks".

Had this happen except it had NO clutch spring?!? Yay spare parts box!!! .

Well I just received words from RedCat and they are sending back my RC.
I hope everything was fixed and in working order.
Now its the waiting game.

Thanks to everyone for helping out.
Appreciate it.
