i just got my new jato last night and i love the looks of it. but to my dissapointment we got snow and its 10 degrees outside. what is the harm of breaking a nitro in while you have it off the ground and in a warm garage? i want to get it running so bad but i cant go outside to do it. if someone could please let me know if you can break it in without having to drive it outside it would help tons. thanks

I am nto sure in the dangers but i am sure it isn't good for the engine because it will be running at such high rpms. I would wait until you can break it in normally outside.

Breaking it in off of the ground voids out one of the biggest points of the heat cycling break in method- the load on the engine. This load is only going to be present when the vehicle is propelling itself on the ground.

However, there is an alternative if you want the load and really want to break it in.

Go buy 4 of these rollers from Harbor Freight-

Then go buy a piece of plywood or find a piece of scrap plywood. Mount the rollers on the piece of plywood where the Jato's tires are- basically, you want the Jato to be able to run freely on the rollers. Then you secure the Jato from the front and back of the truck to the plywood so it can't roll off of the wood.

Time to break it in! Now, one more thing, Nitro is NASTY. You need real good ventilation. If your eyes or nose start to burn, you need better ventilation.

well i got my jato broke in and it runs awesome. so fast. i just put it on a table saw roller system. it worked good and now im up and running. those rollers work great but it took me a little bit to find someone that had some. got it broke in and had to take it out in the snow and try it. definitely impressed

NICE!!!!!!!!!


Have fun with the JJAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAATTTTTTTT TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTOOOOOOOOOOOO OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!!

not a bad idea there with the rollers. i have also seen car engine break in stand/things. i dont remember exacltly, but i think it had throttle control, and some kind of gear box system to put a load on it, or at least thats what it looked like to me as i quickly glanced at it. i wouldnt buy it though, cuz i remember walking around all day thinking, "why would anyone pay that much for a test stand/thinger when you can break it in in you car?!".

I've seen the break-in stands in the magazines that they use on new engines before they dyno them. The ones that I've seen use a prop. inside a housing. That way there is some air flow around the engine, too.
To break it in in cold weather, you could wrap the cooling head in foil tape, or wrap an old sock around it, to keep some heat in.
Make sure you waterproof stuff before you ram it into too many snow banks...

hmm, interesting. i dont think this one had a prop, but whatever.
