Break in and fuel

[nedrey82]

Ok so after having a hard time getting it up and running I eventually got the losi going. Now after I went to my hobby shop yesterday the guy in the store told me to run 5-8 tanks through it on idle which is what I have done ( he is sponsored by jq so I'm assuming he knows his stuff) should I now do the heat cycle? Also I'm using 20% does it matter if I use different brands of fuel even though they are still 20%?

Wow, 5-8 tanks is a lot of idling. You should have been driving it around slowly. You can heat cycle it now if you want to, but it's probably ready to rip on a little bit. Just take it easy for a few more tanks. You can use any 20% fuel you want, but different brands will run slightly different.

If the engine didnt get up to 200 degrees, all that idling was for nil and probably shortened the engines life. The idea of engine break in is to expand and contrast the engines materials, allowing the metals to "seat" together. Running an engine under 200 degrees doesn't allow the materials to expand properly, causing excessive pressure on the rod and bearings. Especially in new engines.

I had ye cooling fins in tin foil and used the heat gun to get her up to 200 then idled her and constantly monitored the temperature.

You should be alright then.

5-8 Idle tanks should be fine for breakin IMO. I would probably start with performance tuning and start squeazing the trigger.

It'll be fine, but you could've been driving it around and saved loads of time on break-in.
