I fired up my plane today

The engine currently in my Venus II (120AX) had been replaced by Hobby Services. It has a handful of tanks through it from the end of last summer. I ran it with the tank mounted at the firewall for initial break-in with the intent of moving the tank back to the CG and reinstalling the pump.

A couple of weeks ago I performed the surgery on the plane. Tank's mounted at CG, lines are all run, etc. I decided to double check the settings so I ran a supplementary tank on the outside of the plane and restored the needles to factory settings. In one small tank of fuel I had the settings dialed in, nice transition, 2300rpm idle and 9000rpm with 10% fuel and a 15x8 APC prop. I ran another small tank of fuel, playing with all ranges of rpm, transition, etc, and boy am I happy with this thing! People say OS engines are broken in after a few tanks. From experience I found that after a few gallons, the transition smooths out, the high end power increases, and the idle rpm drops to sub-2000rpm. It's getting there. One more full gallon of fuel and I'll have better performance with a bigger prop. Oh and my engineering neighbors were around and asked about how to start it. They were like "do you have a starter, or do you 'old skool flip it?'" And I was like "well, it's an OS. I have a starter, but I never really need to use it". With that I turned around, attached the glow ignitor, and she started up on one flip, as usual

These engines are SO EASY! Easy, reliable, durable, and backed by some top notch service.

This feeling I have from OS engines makes the price tag totally worth it!
