Brief Description:  Lycoming IO-390 First Engine Start - Part 01

The first start on the new Lycoming IO-390 from AeroSport went great. No major issues to speak of. The exhaust bolts on the left rear cylinder were a little bit loose, the hall-effect RPM sensors in the mags didn't seem to work, and there was a small fuel leak coming from the fittings on one of the fuel pressure transducers. Other than that, WOW! What a powerful engine! In the video, I only got to about 1/3 throttle and it felt like it wanted to jump off the ground! Really strong sounding and the 4-into-4 Vetterman exhaust really gives the motor a throaty sound. All of the controls (throttle, mixture, and prop) worked as expected. Cycling the prop pitch worked great. Fuel flow was good and I tested feeds from both the left and right tanks. The left and right mags also checked out good as did the kill switch. AeroSport bench ran the engine for 11.5 hours at my request. This should get me well past the critical breakin period. The ease at which it started attests to that as well.

Wow! That's all I've got to say! I can hardly wait to point this baby down the runway and "get 'er done"!

In addition to the usual still picture fair normally attached to the log entries, I've now added complimentary YouTube videos as well! And - they're in full 1080p HDTV resolution too! When the YouTube player comes up, in the lower right hand corner it will say "360p" by default. Select the highest setting that works on your computer without stuttering (480p/720p/1080p). The HDTV versions are amazing clear. I can hardly wait to get some air-to-air shots.
