David Edgemon RV-8 · · PAGE 1. 

December 6, 2009: I have been speaking with David Edgemon during the construction of his RV-8 and finally made the trip to see the airplane in final assembly at the Moontown Airport.  I have shown the construction of Wendell's RV-8 and the work done by Larry Champion on his RV-8.  I did not feel the need to put another RV-8 project in the web site, just the finished results.  As he did with his RV-9A, this one is painted at home in his shop as seen in my earlier postings about David Edgemon.  This time, the paint is covered with a clear coat finish.   He loves the paint scheme that pays homage to the World War II North American P-51 Mustang fighters.

The business end of this bird has a 180 horsepower, fuel-injected, ECI parallel-valve, IO-360 Titan Engine, built by Aero Sport Power.  That large fiberglass air intake is topped with an air filter.  That round aluminum disc on the right side of it is for alternate air in case of an emergency from a clogged air filter.

David had just filled the left fuel tank with 20 gallons of 100 low-lead fuel before my arrival and discovered a leak.  It was quickly determined it was coming from the main fuel line connection on the inboard end of the tank.  The propeller is the same Hartzell constant-speed model from Van's Aircraft as seen on Wendell's RV-8.

Look closely at this photo of the fiberglass fairing around the windshield.   Unlike my windshield which shows the natural green color of the West 1 epoxy, this is all black when viewed from the inside.  David mixed in some black dye when he applied the epoxy to secure the windshield.

The panel is all glass as you can see when it is fully active.  A pair of large-screen Dynon units dominate the center panel.  The GPS on the right side is the Garmin 696.  The yellow light on the left side of the panel is from a micro switch advising the canopy is open or ajar.  And yes, with no passive flight instruments, there is a back-up battery on board.

I took this photo showing the air induction system and throttle body for the engine.  David is pumping out most of the fuel from the left tank into several fuel containers.

There are two independent electronic ignition systems on the engine.  Both of them are from Lightspeed Engineering.  One set of spark plugs is controlled from a crank sensor up front behind the flywheel.  It is the same as on my RV-9A and David's RV-9A partially visible in the background.  The second ignition is controlled from a sensor mounted in the normal magneto location on the engine accessory case near the firewall.

The pitot tube is from Dynon with the angle-of-attack sensor port on it.
