Dear Listers,
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 I normally attached to my log
entries, I've now added 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.
The cameras are Sony HDR-CX550V and HDR-XR550V units and sport 64GB of flash
and a 240GB hard drive respectively. They record in full 1080 HD and Dolby
digital 5.1 surround sound. I have the HDR-CX550V mounted on a head rest
mount on the back of the pilot's seat and the HDR-XR550V is used for tripod
or hand held action capture. The head rest mount is a little too low to
see over my shoulder and I've got an extension ordered that should lift it
well over the obstruction. I edited the various clips down using Adobe
Premiere CS4, which is very nice, btw.
