The "kid" at the LHS told me that nitro cars are not meant to run in winter in CT. Said the best temp was 60*-80*.
I see videos of people running in the snow.
Do settings need to be changed according to outside air temps?

Hey man, I used to think that you couldn't run them in the snow. You'll usually have to adjust your needle settings on a daily basis to adjust for humidity and temp. of course. When you adjust the needles for a nitro engine, you're not only adjusting the engine output, but also the rate at which the engine cools. Running a nitro car in the snow is alright, as long as the car is around room temperature before you start it otherwise it could do damage to the cylinder. Just keep in mind that you may be able to lean out your engine a bit more than usual, but try to keep the mixture semi-rich, I find it will foul your glow plugs pretty quick if you don't.
 
What a great website. I can see myself watching that one a LOT!!

Thanks for your help.
I can't believe the 1st car ran so long with no adjustments or cleaning or maintenance of ANY kind....DOH
 
Nitronewb, get yourself the March 08 issue of X-Treme RC if you can. They have a really good article on page 36 that tells about running in the snow, tuning, and maintenance. Keep in mind that electricity and water don't mix, and the control system on the truck is electrical so you need to take the right precautions and you will be running in the snow for years. If you run in the snow a lot and you have bought the new truck yet, you could consider a Maxx cuz the E-Maxx is set up completely waterproof out of the box, and you can upgrade the T-Maxx with those same parts and have a factory waterproof truck. Plasti-dip works great for waterproofing stuff as it is almost like covering your stuff in spray-on bed liner. only a lot easier to clean up. Good luck, and put up some pics and videos of that truck running in the snow once you get set-up.

Oh yea, in the march issue they are running a special so you can subscribe to XRC for one year and get another subscrition completely free. RC Driver is running a similar special that you can find on their website. There's always so much good stuff that you can learn in a magazine issue, and I've learned a lot from them although it doesn't even compare to this. hmmm, rcnitrotalk magazine anyone??

yeah that is a great site. and I'm sure those guys have like the best cars around, thats why they run so good lol. all i know is mine def did not do that at ALL! but yea it gives you alot of basics and even how to disassembal and assembal and engine. there is also a chapter in there that tells you all about what to do when its hot, cold, humid, dry ect. ect on how to adjust your settings. def a great score with that site. CHECK IT OUT NOOBS!! hehe ( i know i do regularly ) =]

there is a common misconception that the colder the outside Air temp the leaner you want to go...this is not correct...as air gets colder the volume of O2 PPM is greater because it's more dense....cold air will "wring out" the relative humidity in the air allowing for more O2....you should actually be richening your mill as the temps go down.....I won't run below 40deg just because of the super cooling effect you have after the mill shuts down...the temps can drop WAY faster than they really should to keep the metals from premature stresses......
 
I just ordered Xtreme Rc Mag. Looks like a great place to get info. I can't believe how much I've learned in the last few days from the people in this forum and the links provided.
I just tore down the engine on the old car to get familiar. If only I knew what I was doing.....
 
The best way to learn is always to tear into it, these things are just like 1:1 cars in the fact that they are just puzzles, and when you figure out why the pieces fit together, then you can figure out anything.
