Ok i wanted to break in my rc10gt today but its -5 degrees here in mn so how warm out should it be to break in and drive my gt?

That might be too cold. The engine needs to get up to about 230 F to get the parts to break in. Many people use aluminum foil to keep some head in on the cooling head, but I wouldn't risk it even though I know it is hard to wait.

I have driven my Nitro in 3 degree weather. I broke it in when it was 17-20F.

I actually just got done from running my truck in about 0 degree weather. Trust me, when it's really cold temps like you all are talking about, your patience decreases a lot. When you lose your patience, you lose your train of thought to do things thoroughly. Then, something bad happens. I know it's hard to wait, it really is, but if I were you; I would just wait until it was a little warmer out just so that you don't wreck a brand new engine. That's just my $0.02 though.

well i was thinkin about doin it in my garage and put it on a stand and break it in. I was also going to use one of those propane heaters so what u think about that?

Hey wassupmiller what part of mn are you from?

rice county

i'm just beginning to break mine in. Wisconsin here and we're at -15 right now. I did it in the garage though, but I've got a 3 car so i could drive it around a little. Just don't let the fumes get to ya.

I don't reccommend breaking it in with no load on the engine. Wait till it gets warmer and follow the instructions that came with the engine.

Amen.
