Hello again everybody, Today I'm seeking professional advice on engine break-in. I have a hobbystar /superstar trainer with an O.S. LA 40 engine. I ran 1 full tank of Omega 15% fuel through at full throttle and needle settings as described per O.S. manual No Problems, I'm just a little fuzzy on where the manfg. suggests to start leaning on the 2nd tank with the needle valve after each flight, but I'll be doing this from the ground not flying, (not trained Yet) should I just tweak a little leaner about every 5 minutes or so? and approx. how many tanks before break-in is complete? I have nitro experience with monster trucks, but this is my first airplane engine p.s. if your asking yourself why is this guy breaking in the engine on the ground and not flying it's because I spoke to someone from a club I plan to join and he suggested I have the engine broke in before showing up at the field.

Run 3 or 4 tanks through it, set it a bit leaner each time, but be sure to not go too lean. Once you've done this, put it in the plane and go to the field. BTW, since you wanted "professional advice", that'll be $5!

Exactly.


(Will that get me off your block list?)

Why are some of the post replys being edited?

Sometimes after a person finishes a post they notice a mistake or decide to add something, so they edit it.

Block list? Are you on his block list?

No but I may be on yours from times past. I checked that out. It blocks the replies but still shows the name in the same slot, so all you need to do is a brief click and the whole thing comes up? Does not really block does it since you see the name, a person is going to want to look. I dunno
