I sure wished you were on the east coast ( North Carolina) I would give you a space

Same here. I'm in the midwest with a 60'x100' fully equipped machine shed, a 3

| Subject: | Circuit To Combine Mag P-Lead For RPM Measurements |
Has anyone found a device or circuit to pick off the output from the P leads on
the left and right mags for feeding to an RPM measuring device such as the GRT
EIS-4000? The EIS-4000 only has a single RPM input. The installation manual
suggests installing a SPDT switch between the left/right mags and then to the
input on the EIS-4000 for manually switching between the mags during drop testing.
But that's pretty hoekey. Seems like someone should have come up with
a simple prioritized switching circuit that would, say, always read the left
mag p lead unless there wasn't a signal, then read the right mag P lead output.
In my "spare time" maybe I'll make one if there isn't something already out
there like this.
I thought that once upon a time I saw an electronic gizmo you could screw into
the standard tack drive that would give an electronic output. Anyone have a line
on this device and whether its compatible with the GRT EIS?
Thanks!!

I can offer nothing on the pick off option from the P lead....but... The GRT EIS
4000 now can take 2 inputs for RPM and displays RPM #1 if it is present . Your
older unit may be upgradable.

Yes, I do remember that thread. In fact, I have those pickups installed, but I'm
not getting any reading on the EIS-4000 with either one of them. I'm using
the vent hole closest to the engine block. Have you successfully interfaced
them to the EIS-4000?

What are you using for excitation voltage to the sender?
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).

Hi all,
I am building an RV 8 and have one of the first pre-punch fuselages.
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?

Had you already drilled the holes for mounting? 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).

Michael,
I have a dash1 fuselage and the fit was the same as yours. I was able to
trim the bottom of the vertical for clearance and still have enough
edge distance.

| Subject: | First Engine Start - Lycoming IO-390 Purrrrrzzz! |
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.
