| some put props on and bench run in , but i already mounted mine in the heli. my last one didnt have a ringed piston , but how ever my new 46 does. on my last motor for first run ran sloppy rich and took it to hover about 1 foot off ground for about 10 min then after run oil and lt cool down 4, 1 hr and repeat, but slowly increasing rpm and extending time a minute each run.

Most "break in" their motors in the heli.... Your motor does not need to be "slobbering rich", just pretty rich during the first few tanks. I think it would be best to do a combination of hovering and FF during break in and you can skip the part about the after run oil at the end of the tank and waiting an hour. That will buy you nothing except wasting time.....
After the first three or so tanks, start leaning out the needle a little at a time until you sneak up on where you want to be.... I would say a couple of gallons of fuel should do the trick.... |
