How To: Break in a Nitro RC engine

Break in a Nitro RC engine

This video is on my break in method. I use half of the new school break in method and half of the traxxas. My method goes like this:

tank 1: 1/4 throttle, leaned to 200 degrees, no full brakes and really no time limits on the throttle ever to keep it moving like the new school method.

Tank 2 and 3 are half throttle tanks. Same as above. You can tune the engine a little more if you would like. Dont fully tune though as you want to keep it a little bit rich.

Tanks 4 and 5 are full throttle. Again with the above, tune a little more if you want. I have mine so that it is in ball part by the time that the last tank is done. Keep the truck moving like the new school method.

This vid is on the new school break in method. The nice part about this method is that heat is good and it is the focus of the break in. Once you achieve a constant 200 degrees F then you finish that tank and move on to the next method. For the first cycle you run for 3 minutes and then check the engine temp. If you are at 200 degrees then move on. If not, lean it to gain more heat or richen it to lessen heat. Cool the engine at bottom dead center BDC and then start the engine back up. Run the engine for another 3 minutes and then see where the temp is.

You will repeat this till you are constantly at 200 degrees.

When you are then you will do 4 minutes till with half throttle variances. If you are maintaining 200 degrees then move on. If not, then richen or lean as you need to.

On the last leg, you will run for 5 minute intervals at full throttle. Maintaining 200 degrees will allow you to graduate to a broken in engine.
This video is on how to select fuel and glow plugs prior to break in. Information that this contains his how to troubleshoot and break in the kit based off of the glow plug, how much oil is good in fuel, and what nitro percent is good for the fuel.
