Atul,
Like I said, I've got 35 flights on the motor so far, and no issues. It's been a dream. It's the cleanest, smoothest running motor I've ever had.
I have been lazy and have not tached the motor, but I'm running Coolpower 20% heli in it right now, and it will swing a 19x11 with no trouble so far.
I ran the motor today. Used 8% oil and 15% Nitro. Used an 18x10 prop and a 580cc Tettra tank. I ran at a fast idle (between 2700 and 3000 RPM) for three runs of 12-14 mins each. Not very noisy either. I used a Hatori header and 821 mufffler.
You're right: it runs like a dream; super smooth, incredible transition and little or no vibration. The low oil does not seem to bother it either.
WIth 8% oil, there still seemed to be some visible smoke. Could this be because the engine is brand new? I'm thinking of going down to 5% oil.
The needle was at 1 3/4 turns, which seemed to be a little rich, though the motor did not get bogged down even at a 1400 RPM idle.
Question: are there any specific run-in instructions? How much more do I have to run it at a low idle before I set the high-speed? Any advise is much appreciated.
