Matt,
I believe the tranducer for RPM is IE VTACHGEN 2 from Van's and it works
fine on my RV-9A straight off the tach port on the back of the engine.
I have a Rocky Mountain micromonitor which accepts a similar pulse from
the P-lead. It asks how many pulses per engine rotation in the setup
so you could operate it on just one P-lead, or both. They instruct the
builder to just put a capacitor in the lead to the instrument, which
allows you to "y" the two leads/capacitors to one signal lead.
Great video of first start.

Subject: RV-List: 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."

Subject: | FS: RV-7A ~80% complete |
I've decided to sell my RV-7A project. It's just dragged on and on, and
I've lost interest in completing it. I have more interest in just flying my
Challenger II.
Engine is Subaru WRX STi 2.5 L supercharged. All the bugs are worked out
of the original Eggenfellner product. Most Eggenfellner-supplied
components have been replaced; SDS ECU, custom radiators, new wiring
harness, supercharger gearing. Engine runs great, and all it needs is
probably some more fine-tuning of the SDS ECU. John Moody in Australia has
been flying his awhile. Includes latest Gen3 rev 4 PSRU, installed.
Includes MT7 electric prop, installed.
Three EFIS systems installed - Blue Mountain "gold box" EFIS/One, GRT
Horizon, and Dynon D10. Blue Mountain AP installed. GRT EIS installed
Full Garmin stack trays installed & SL-30 included. Sandia TSOd encoder,
Tipup canopy completed but not final-installed.
Needs rear window installed, 1 panel each wing installed, top fuse panel
behind window and fwd of canopy installed (left out for wiring access). No
fiberglass work done.
Includes Advanced Flight Systems AoA, wig-wag HID lights, bulletproof
electrical system based on Bob Nuckolls' designs and Hyperion products, low
fuel warning, low coolant warning, fuel pressure warning, electric flaps,
electric trim, custom console, heater, Oregon Aero seats, Hooker harness,
Show Planes Flaps Positioning System, Infinity Aerospace grips, cabin
lighting, custom baggage compartment and other customizations (see my custom
page http://www.meyette.us/custom.htm ). Includes finishing kit and all
parts (except remaining Garmin components) to finish it. All gear mounted
and brakes installed. Van's front gear leg SB installed. Panel complete,
except Garmin wiring.
Empennage is done & final-installed. Flaps & ailerons all done. Wings
not installed.
And much more - this is a list off the top of my head of some of the main
components.
Entire project very extensively documented at
http://www.meyette.us/RV-7Ahome.htm No effort or expense spared in doing
everything RIGHT.
Only asking $55k for it - way less than cost and making the FWF essentially
FREE. Will also trade for an RV-12

Subject: | Landing gear/engine mount cracks 1470 hrs RV-6 |
1. Thanks to Charles Kuss for the info on how to remove the adhesive
under flap wear strip.
2. Cracks in engine mount at loweroutboard firewall mount bosses: RV6
with 1470 hrs TT
Called Van's; they said it has been happening on some aircraft and to
get it welded in place within the next 50 hrs. They suggested adding a
gusset plate that has been added to all RV7s. We pulled engine/gear
assembly forward and clear of firewall and welded the cracks then added
the gusset plate on both sides. This aircraft has been used for allot
of training and has seen some hard landings.........although only found
the cracks during this February annual condition inspection even though
a couple of the hard landings had me looking closely about 400 hrs
ago. The cracks were in the weld bead itself on the underside of the
mount bolt boss.
Landings will be monitored a bit more closely from here on out. Heh,
heh!
