new problem

[way2fast]

well, i put a sock over the head, and ran it in circles at 1/4 throttle. Anyways, i shut it off to let it cool down out side, and now it wont start for poop. WHat could be wrong?? It started for 2 seconds then it shut off again, not it wont start. What could be wrong??

it seems like it really want to start, but no spark. I'm pretty sure its the glow plug, but i really can't take it out, and i can't find an 8mm wrench

There's not much we can tell you if you don't know if the glow plug lights.

Anyway, nitro engines HATE the cold. You're killing it slowly.

lol, its not dying i can guarantee you that for sure man. I found a 8 mm wrench, and took the glow plug out. And i checked to see if it worked, and it did light up. I put it back in the car, and it fired right up, so problem is solved

It's brand new, you haven't done a proper break in on it, you're running it in the cold.
When springtime rolls around, don't expect to get very good performance out of it.
They have to run rich in order to run in the cold. That puts an extra load on it.

what i can for sure tell you is the fact that it started with absolutly no problems. The weather when i got it running was pretty good outside, it was above 0 Celcius. Anyways, it was running rich, and it was running good, because i could tell that it was spitting some fuel from the pipe. Anyways, i fully let the motor warm up, and very lightly pushed the throttle down so that it would barely move. I pulled the sock up all the way when it was doing circles and it was keeping the right heat, and cooling down normally and how it should. It ran perfect

But you are killing it slowly.....lol. Trust us, most of us have been there done that already. It sounds like you have a pretty good handle on things, but rest assured, 2 or 3 gallons in the freezing cold and it'll be worn out.

 

[olds97_lss]

If not worn out, it will be a permanent "winter" engine. I run old tired engines in the winter because winter kills them. Especially if snow is on the ground. Eventually, snow will end up on the engine, which cools it rapidly (even with a sock on it). The sock actually makes it worse as it absorbs the melted snow and holds the water against the head.

All we are telling you is that nitro and cold don't mix well. Start saving $ now so you can grab a new engine in the spring as there is a high likelihood that once the temps are above 50F (10C), the engine your running probably will run pretty weak. Just keep it for next winter though.

Of course it runs fine now. It's brand new, but the strain you are putting on it will really take a toll when you realize it will NEVER run to its full potential.

well, I'm not going to be running this model when the weather is below freezing. Today it was good outside for it. I didnt get any water on the head or anything, so its fine. I just dont get why you guys keep saying that I'm killing it slowly. I mean its a normal motor that runs on alcohol, nothing wrong with that. I'm not too sure how you guys see this from your point. The local guy who sold me the rc told me he runs his in snow and nothing ever happens

The guy in the store is there to sell it to you. He'll also try to sell you a new engine later. You've heard it from the best of us. You've heard it from guys with MANY years of experience with nitro engines.
We're telling you, go enjoy it, but it will have a limited life without EVER reaching its full potential because the proper heat cycling can't be done in the cold, and running rich puts an additional load on it.
You don't want to take our advise, so do whatever you want.
According to your IP, you're in Canada. I'm about 800 miles south of you and it's too cold to run a nitro engine here.
The worst that can happen is that you'll buy another engine from the guy in the hobby shop when you find out that it just doesn't run like the others in the spring.

well here it was good today. Ill do 10-15 tanks of gas break in if i have to. I want this motor to last, and give its full power. Putting this toy away is just like throwing 500 bucks out the window. Its there, but i can't use it. There is gotta be some way of breaking in the motor in winter time

Sometimes you just gotta try things yourself and come to your own conclusions,good or bad.

 

[2revo1maxx]

It's not just an engine that runs on alcohol. It's a nitro engine with a TAPERED sleeve. The sleeve is tight at the top. Getting to at least 200f degrees is critical because the chrome plated brass sleeve will expand more than the aluminum piston, allowing the engine to turn more freely. Rapid cooling from sucking in cold air will cause the sleeve to cool and clamp down on the piston. This will cause premature wear. You might get away with it for a few gallons. You may even be able to lean it out and get some good power out of it in the spring too, but you're killing it slowly. I can't blame ya for wanting to drive it, but you've gotta understand what we're all trying to tell you. We all know you're going to run it, so at least try to do it on the above 0 celcius days.

Not gonna' happen.

For one, it's not a toy. It's a machine. Putting it away is like putting it in the bank. What you're doing now is throwing it out the window into the cold.

READ THIS again. I didn't write it. It's written by a world class nitro racer. I just copied it for the knowledge.

You asked for advise, you refuse to take it. You're on your own. I give up. :hi:

 

[w bill]

Go for it fun comes at an expense theres a lot of experience out here talking at you the only one that is gona hug you is the hobby shop when you order that new engine that weeping you hear is your wallet!:

 

[yammaha]

Rolex is right, your nitro will wear out a lot quicker running it in the cold.

I just got done breaking in my S-Maxx in 30 degree temperatures (cause I'm a newbie) and the attached pictures was the result. A bunch of people have told me its terrible for the engine during the break in period.

I shouldn't have said Breaking in... I meant Breaking my S-Maxx

I meant 30 degrees Fahrenheit too...
