View Full Version : cold temps with using summit
08-14-2011, 01:39 PM
just wanted to know if anyone has used their stock summits in -45 degree weather, i live in fairbanks alaska where it gets to -70? any mods that might need to be done would be great to know, and also, how much more performance do you get with a stock summit with using lipo batteries and will they handle -45? thanks in advance for whatever yall have for me and sorry if i have asked a question that is asked alot. in afghanistan right now internet is too slow to set here and search through the forum.
I'm not %100 on this but I don't know if lipos will like that cold of weather. The truck itself would probably be fine, just be aware that the plastic will be brittle because of the cold temps.

Lipos hate cold weather ( when being used )- they need to be kept warm until you use them ( ~100*F is an ideal starting temp ). A good trick is to keep them against your body on the inside of your jacket right up until you actually plug them in and run the truck. Otherwise yeah, beware the plastic becoming brittle in cold weather and bare in mind diff fluid will effectively thicken up in cold weather, as will shock oil so a lighter weight might be in order to off set the change.

i guess its the same concept as with real vehicles when it comes to oils, do they make synthetic oils for the traxxas? also will brushless systems handle snow and cold temps like that? im not looking for 60 mph just more than stock for a little more get up and go, and longer play time, i have 4200 nihm right now and only get 15 minutes or so of play time. i was thinking about just getting some lipos and get a emaxx or stampede for a really good basher? any ideas would be appreciated.

i guess waterproof would be ideal for the snow? or is there a brushless system that comes waterproof? really want to try brushless but will stay with a brushed setup if i can acheive the goals i want with out breaking the bank. seeing as how a emaxx or stampede is 400. i guess that would be my cap with upgrading the summit

I ran mine in maybe -10 or so with no problems. I dont run lipos so I dont have any experience there but the truck it self was fine. I made a blanket that wrapped over the motor and most the servos to help keep snow and frost from packing in there too tight. As far as waterproof in the snow, when its real cold I didnt have a prob but when it gets warmer out and it melts on the truck it gets pretty wet. The stock system handled it well! Good luck man..

Lipo and -45... Never.
I ruined a nice set of Lipo's in the cold, and nowhere near that cold...
Plastic will be brittle like already said. Nimh and a nice addition is a chassis cover. Just found that all the snow packing in makes alot of extra weight, the cover will prevent some of that from happening.

I used mine all last winter here on Canada. I have the tekin in it and ran with an outerwears cover. It worked great. Never got any water or snow on the electrics.

I have used LIpoFe batteries to -13 ° C for hours without much trouble, the option to keep warm and isolated until the time of use is essential.
Lipo Batteries has been tested in a Summit at 8ēC below zero for five hours without appreciable loss, however the performance of nimh was mediocre. You may have other problems like the accumulation of ice I had a broken steering servo due to the accumulation in front links.
Do not hesitate to put self-tapping screws in the tires, introduced from the inside out.

The oils used in the traxxas diffs and shocks is synthetic, as it is with pretty much all r/c vehicles unless I'm mistaken; silicon based usually. You can use any brand of oil you like really, just think about the weight..
