Thanks for the video. Was nice to learn the big end bearing sizes, from 32mm to 38mm. Wish there was more specs on this engine.

Great interview and subject! I wish they could get that TBO closer to 2000. Thanks for the great content.

Thanks 👍

Thanks that was very informative. If you are running this engine primarily on 100LL, how often should you do oil changes? How about spark plugs??

[@ultralightnews]

25 hours on oil changes, 50 hours on spark plugs.

You forgot to discuss the price of the 915 being about $38k and that comes with a 1200 hour tbo which I'm sure a reman will cost a tad more than a 100 hp 912.
