John Vander Horck RV-12


After three years and 1,800 hours of construction, I’m proud to acknowledge the first flight of my Rotax 912 ULS powered Van’s RV-12 E-LSA, serial number 120850, N850VH, on May 20, 2017, at Archuleta County Stevens Field (KPSO) Pagosa Springs, Colorado, field elevation 7,664′ (morning density altitude well over 9,000′).

It is equipped with a single 10″ Dynon SkyView Touch EFIS, with autopilot, SV-AP Panel, SV-Knob Panel and ADSB In and Out, Garmin Com radio and full Flightline interior. All interior aluminum was hand Scotch Brighted and primed with Stewart Systems water-based primer before construction. The exterior paint scheme was designed by Ernest Tulfer. The exterior paint is Sherwin-Williams ACRY GLO and JET GLO expertly applied by Dwight Tulfer of Animas Aero Design, Durango, Colorado.

The construction, initial flight tests, Production Acceptance Procedures, final tweaking and electrical wring-out could not have been accomplished without the able assistance of my friend and hangar mate Craig Taylor, a retired Viet Nam Navy A-7 driver and Van’s RV-8 pilot; Michael Arbuthnot, friend and Glasair III builder and pilot; and my wife Stacey. I also have to acknowledge the assistance, support and timely responses from both Van’s Aircraft and Dynon technical support to my several inquiries. Prior to my first flight, I took six hours of transition training with Van’s Aircraft, Aurora, Oregon. It is highly recommended.

For a more finished look, I added the optional glare shield, wheel pants, full strobe, navigation and landing lighting and USB power for my Ram mounted 10″ iPad running Foreflight. I also added the after-market stabilator tips (now available from Van’s Aircraft) and fully enclosed all of the exposed tooling holes in the wingtips.

The aircraft flies great–thanks Van’s!
