Same here. I'm in the midwest with a 60'x100' fully equipped machine shed, a 3 bedroom, 2800' sq ft. house in the country with only 1 bedroom in use & no time to work on the plane.

Honestly, I haven't run my engine yet, but I was able to get the EIS to indicate an RPM readind by "waving" a small magnet across the sensor. The excitation voltage has to be 12 volts or so (a 5 volt source doesn't produce enough signal voltage for the EIS). Skylor Sent from my iPhone.

Please reference drawing 78 if you want to see the spot. I put the HS on and bolted it in place. I then put the rudder on but found the forward end of the rudder hit the rear fuselage top skin. I thought I had fit all this together before, but think maybe I had never really bolted the HS down. I double checked and think I have all the appropriate spacers (just one 1/8th inch spacer on each side under the HS and on top of the deck. I started filing down the nose of the VS to get it to fit. It needs about 3/8 of an inch to fit without touching the rear top fuselage skin. I took off all the skin in front of the bottom rib but will need about 3/16 off that. I think that the minimum rivet to edge distance will be okay, but wondered if I have done something wrong. It doesn't seem right, somehow. I thought I would see if anyone else has had this issue before I file off something that I should not be removing. Thoughts?

I put mine on too low (with the rear top skin not on the plane) and so had the move it up and re-drill (replacing the bars it bolts into).

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. HDTV Videos (Select the 480p, 720p, or 1080p HD Quality Versions!)
