Default Breaking an Engine in During the Winter

I just got an HPI MT2 and I really wanna start breaking it in. It's pretty cold outside, about 26 degrees. Is there anything wrong with breaking it in in these temperature. Thanks alot for your help.

Cover the head in aluminum foil, with a small hole for the ignitor. Then, heat the engine up to operating temp (200ish) with a hair dryer or heat gun. Run the break in with the body on, and when you are done with a tank of gas, bring the car inside to cool at room tempature. Its also best to heat it up at room tempature, and don't let it sit outside too long.

I'm assuming that the foil goes around the cooling head(heatsink) and not the acutal head of the engine. Is that correct? Thanks

I try and get it to cover as much of the engine as possible without getting in risk of getting caught in any moving parts...if its REALLY that cold out, then you want to keep in all the heat you can.

I do this in my house, here's what I do:

1. Take a plastic 500ml pop bottle and cut off the bottom of it.

2. Cut a peice of carboard the width of your window and 10 inches high with a hole in it the size of the bottom of the pop bottle.

3. Create a flexible "tube" with brown paper bag, tape one end to the cardboard in the window and the other to the pop bottle (I use duct tape)

4. Place the end of the pop bottle on the end of the cars exhaust and use electrical tape to seal it off.

5. Optional: Place a small computer fan (12V) at the opening of the carboard to vent the exhaust out, connect to power supply.

Prop the car up level with the window on your pit table and fire it up. All the exhaust will be vented outside and the oil residue will be captured by the plastic pop bottle. Don't do this when someone is sleeping, it will be loud!!!

By doing it this way you will be in the comfort of your home, at you pit table and the car will never be in the super cold air.

It's kinda crude but I've made this setup a couple times and it works like charm.
