The Twin Jag project started life as a completed RV-6A, which was built and flew for 250 hours.
Some modifications include, but not limited to:

  1. Installing 2 Corvair 3000cc 120hp direct drive with Weseman 5th bearings. Weseman billet crankshafts.
  2. Custom made carbon fiber props.
  3. Unique prop brake system in lieu of constant speed feathering props.
  4. Increased wingspan by 40″.
  5. Installed RV-9 tail.
  6. Re-designing nose gear with 4130 tubular gear & urethane dampening (similar to RV-10).
  7. Many more mods.

The Twin Jag is a side-by-side 2 seat twin-engine cross country aircraft. It will be IFR capable with dual Dynon Skyview EFIS.

By January 2013, both nacelles complete. Custom motor mounts being fabricated. Riveting right wing extension now, left wing extension riveting to follow. Center console 75% complete. Fabricating nose gear/baggage shelf in next few weeks. All fibreglass work still in rough stages of completion…lots of filling & sanding ahead.

Engines: 2 Corvair 3000cc 120hp

Jacobs 1910 Multiplane

The 1910 Jacobs Multiplane [also identified as the Jacobs-Emerson multiplane] was the creation of Henry William Jacobs of Atchison, Kansas. It had quadruplane wings and tail and two engines, each driving a propeller.

Jacobs used two improved air-cooled 35hp engines he invented, to replace the two original underpowered engines [Emersons?], with which the plane flew in 1910.

It was displayed on the New York Aero Exhibition 1912. Jacobs had formed with others the firm “Multiplane Limited” in Kansas to build the machine and eventually sell it to the market and a brochure of 16 pages was produced.
