O-Twisted-IL. Much improved.

O-Twisted-IL (InLine cockpit). Shedding a lot of weight from the seriously pudgy O-Twisted-FTP, it has made great gains in survivability. Still needs more twiddling with the AI and control authority to tame its desire to flip a 180 degree pitch when starting battle - without making it fly like a brick the rest of the time.

If it survives the first missile volley, watch your back, top, bottom...

The aft fuel tank has been emptied. Engine gimbaling is restricted to yaw because it needs no help with pitch or roll. Two ammo boxes and the top Vulcan deleted. The biggest visual change is the inline cockpit and nose intake. The intakes were removed from the rear with two relocated to the forward sides. The intake on the bottom is to cure lower engine flameout issues during hard pitch up. That dramatically improved its survival rate. The forward intakes may not be needed, haven't tested without them since adding the bottom one. The airbrakes are gone, they didn't seem to be doing much for yaw control and added weight.

For manual flying, don't try to flip it like a Babylon 5 Starfury, keep your speed up and you'll do well.

This plane has been superseded already. See the last post here. Note that it will need the one customized part linked in the post. It's not on KerbalX yet due to the experimental nature of lighter weight, structural only versions of the MK2 parts, which should be incorporated in the revived revival of ReStock.

For this plane you might try editing the BDA AI settings, shifting the nose and wingtip canards back to push the COL back, then setting all control surfaces to 150% authority. Weight and maneuverability will still be impaired by the heavier bi-couplers.

I still can't figure out how the Falken doesn't flip out crazy with pitch despite its COL being nearly co-incident with its COM.
