    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. Ian Brown "Time: 10:28:22 AM PST US From: Matt Dralle <dralle@matronics.com> 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 23:32:00

    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! Ron Vandervort
