The main thing Ron wanted me to add, was a better rendition of the unique air brakes, which pivot on their center, and protrude both above and below the wing. This is Ron Norvel's xp9 Westland Wyvern, updated to xp11, with additional 3d cockpit, new engine sounds (thanks to Danhopgood), new red paint livery option, and and armed version too. panel is not very good, neither are the textures, but it's an entertaining little aircraft to wring out and I wanted to share it with anyone who's interested. No speed brakes makes slowing it down for landing a bit of a challenge, but once you've shed the speed it'll float down on full flaps like a gentle leaf. She's a bit of a sweetheart really, very hard to stall and responsive to controls through the speed range. Feel free to make it better/more realistic and submit an improved version. This version probably flies better than it should. I don't claim this is accurate beyond appearance, wingspan and length. I have built this plane to the best of my ability assuming a slightly shrunken version of the BMW 003 engine with 1700lbs thrust and guessed at weights and airfoils. Here's a little something I've always been fascinated with: This was one of Messerschmitt's submissions for the WW2 emergency fighter program, as far as I'm aware it never went beyond a sketch proposal, but I have always been intrigued by it's simple, elegant design. Overall I am quite happy with this as I remember this bird in flight from my youth and it commanded respect when ever I saw it. The liveries also are getting more worh but me and Gimp or Krita is still very slow. The fuselage was lengthened to 136 ft as the Yuko and a entry level 3D cockpit has been added (which I am still working on). This is mainly based on the Jacques Brault Britannia migrated tp XP11 by Sean McLeod. The resulting aircraft had lower speed and service ceiling, but it had two bomb bays and greatly extended loiter times. Their first use of it was to build the heavily modified Canadair CL-28 Argus patrol aircraft (RCAF designation CP-107) that combined the Britannia's wings and tail sections with a new fuselage and engines. In the 1950s, Canadair acquired a licence to build the Bristol Britannia airliner.

The aircraft is named after the Canadian territory of Yukon. Although innovative, only a small number of the aircraft were produced for the Royal Canadian Air Force (RCAF) (as the CC-106 Yukon), and for commercial operators worldwide. The Canadair CL-44 was a Canadian turboprop airliner and cargo aircraft based on the Bristol Britannia that was developed and produced by Canadair in the late 1950s and early 1960s.
