X-159V2 but with larger wingspan. More fuel, larger ailerons, wing has been moved forward as well as the landing gear. Shallower tailstrike angle, so the approach speed has only reduced by about 10 KIAS.

Personally I prefer the V2 but the W is better for the weaponized variants I plan on adding soon (wing is closer to the CoG so adding weaponry is less destabilizing as well as the increased wing area helping with the weight).

This plane really reminds me of the MiG-23MLD

Below is just the X-159V2’s description (slightly edited to adjust for the different aircraft):

Supersonic “fighter”. FLCS testbed with spaghetti code.

In all honesty I don’t think anyone should look too far into the funky trees aspect of this airplane. It’s a bit messy, convoluted, and probably has a few variables that could be entirely removed.

I’ve been steadily working on this for a while (all the way up to W, lot of variants) and this was the second one I felt super comfortable posting. As opposed to previous versions, this one has flaperons, roll and yaw dampeners, and a few other items.

A few quirks/points with this aircraft:

• With gear down, the canards aim for about 8 degrees AoA
• The flap mode with gear down (LG/AF) is the same as alt flaps (Activate 2)
• LG/AF Flaps have plus/minus 10 degrees of flaps based on pitch commands
• Norm flaps are controlled via AoA
• Tailstrike is around 9-10.5 degrees
• PSt (Post Stall / Super-maneuverability, Activate 5) adds throw for elevons and canards as well as increases their response to AoA
• Canards only command roll in PSt mode
• S-FLCS (Simple FLCS, Activate 1) reverts to a very basic control system. Canards are disabled, flaps are disabled, no dampeners, slightly less control throw, and reduced AoA compensation. I don’t recommend this mode but I didn’t want to remove it either
• You shouldn’t need a drag chute (Activate 4) for landing, the aircraft is fairly easy to aerobrake.
• The refueling probe is incredibly far forward in the nose, I haven’t really worried about it as I don’t refuel often. My apologies
• The engine has a faster response at higher power settings. In other words, it increases from 95-100% faster than it increases from 0-5%. This is (in my opinion) more realistic to real life aircraft.
• Approach power is close to 10-12% Throttle

Instructions

Action Groups:

1 -> Backup(simple) flcs
2 -> Alt Flaps
3 -> Refuel Probe
4 -> Drag Chute
5 -> Supermaneuverability / Post Stall (Only reccommended under 400 kias)
8 -> Engine (8 is automatically on, turning off will stop the engine)

Vapp ~ 130-140 kias
Vr ~ 105 kias
Vflaps / Vgear (gear extended / alt flaps speed) ~ 250 kias

Max pitch on ground (ie: max pitch without tailstrike) ~ 11-12 degrees

I just think the plane is neat because of the FLCS, it’s nice to think I created something sorta complex (and that it works!). The aircraft isn’t too special, curious what the community thinks.

Cheers!
