CV-26K Legionnaire is a major upgrade of the CV-26N Taurus+ aircraft. It is a military, tilt-rotor, heavy-lift, medium-sized rotorcraft capable of a large variety of missions. It is equipped with the:
- AN/APN-381 multimode navigation radar – derived version of AN/APG-66 radar (formerly used on F-16A Fighting Falcon) consisting of precised navigation and air-to-ground modes including Monopulse Ground Mapping (MGM), Doppler Beam Sharpening (DBS), high resolution Synthetic Aperture Radar (SAR), Terrain Avoidance/Terrain Following (TA/TF), skin paint (for Station KEeping; SKE), maritime detection, weather/turbulence detection, wind shear alert, and ballistic wind measurement (for precision airdrop)
-AN/APQ-190 Beacon Tracking Radar (BTR) – side-looking radar designed to search, acquire, and track ground beacon signal (X-band transponder) located at a friendly position from 10 nautical miles, beacon coordinate is used as a reference point for ground troop to give the gunship a bearing and range from the beacon to the desired target
-AN/AAQ-86 Infrared Detecting Set (IDS) – long-wave infrared (LWIR) band Forward Looking Infrared (FLIR) (mounted on top of the windshield)
-AN/ALR-99 – digital Radar warning receiver (RWR)
-AN/AAR-134 – UV/IR-based Missile Approach Warning and Avoidance System (MAWAS)
-AN/ALQ-196 Low-Band Jammer (LBJ) – low frequency DRFM jammer-based ECM
-AN/AAQ-84 Nemesis – laser-based Directional Infrared Counter Measures (DIRCM) (mounted on the rear fuselage near the rampdoor)
-AN/ALE-47 Countermeasure Dispensing System (CMDS) – chaff/flare dispenser
-hoist mechanisms, ramp door, side-doors
and can carry multiple ordnance in 8 hard points (4 at forward main wings and 4 sideways). The -K variant is specialized for ground attack (gunship), deep-impact infiltration, Special Forces deploy and extract and behind-enemy-lines CSAR missions.

-------------------------------

For T/O: Trim aircraft at 1 dash above reset, keep VTOL nacelles at the middle and slowly place throttle at 60%. Once you are airborne, slowly place throttle at 70-80% and move VTOL gradually forward. Trim the aircraft carefully so as to achieve level flight and/or positive climb of rate.

For Hover Landing: Trim aircraft full fwd, throttle at 46% and VTOL at the middle. As approaching the ground (70-80ft) increase throttle at 55-60% and hover aircraft above desired touchdown point. For touchdown, decrease slowly the throttle below 30% with the rotorcraft completely level.

--------------------
AG1 + Trim: Rampdoor and Sidedoors operation
AG2 + Trim: Fuel Boom extention
AG3: Navigation and anti-collision lights for night operations
AG4 + Trim: Hoist mechanism extention
AG8: RCR de-activation for enhanced stability at fwd flight and airspeed above 400+ mph.

---------------------
WARNING: IT FLIES BETTER WITH A JOYSTICK OR A GAME CONTROLLER
--------------------------
After some practice you will be able to hover and perform many maneuvers. Pay attention to yaw inputs and corrections and be smooth and positive in control every time. Please have in mind to keep the CG in current position for better stability and performance. Have fun and leave a comment if you have any question or any suggestions for improvement.

Upvote and many regards for the original craft and its creator Ahtzee. He provided a great aircraft body for me to start experimenting and keep upgrading my design.
