Can someone fix this thing's flight model? This kind of shit is out of my skill level, I desperately need help. Bonus points if you intentionally put COM aft of COL and add a FBW system to counteract that.
Everything is fucked, the flaps don't work properly, the canards don't do their thing, and it produces too much lift (though this version I uploaded doesn't have that problem).

Sorry, but I probably didn't specify what problem(s) should be fixed.
.
First of course, the lift scale on the main wings are wrong. They produce too much lift, and if I put them to their original values, it'd just make the plane do a cobra on takeoff.
.
Second problem is, it's really janky at pitch. Sometimes it just rolls while pitching, it isn't really smooth at that.
.
Third problem, it barely even rolls at all. I already tried increasing the lift scale on roll, but it just contributes to the first problem.
.
And last, the front flaps bury the craft to the ground. I removed the lift scale on the flaps on this, they contribute even more to the first problem.
@TRD Have you tried to use funky trees to make Fly By Wire simulation?
I've heard that real aircraft with this design needed FBW to actually fly or you would create the air coffin.
Ok i might if I have the time @Bobyo
@flightdesigner nono go ahead. Mine was pretty crude and simple. And it also looks bad. If you can make it nicer then sure go ahead
@flightdesigner Yeah sure do it, tbh what he did didn't kinda solve the problem. I will be fixing it myself anyway, but you can give it a shot.
@TRD6932 I know that @Bobyo already fixed it but can I😿
@GorillaGuerrilla Yeah, the fiy-by-wire will be next. I just have to make a blueprint accurate wing with control surfaces with fuselages, then put the actual wings and the FBW.
@TRD6932 i am starting to like this thing, as usual.
just some little tweaks to the numbers in the fbw already works wonders. just check out this improvement
@TRD6932 it is fixable, but unorthodox and complicated
@TRD6932 seriously u need more than just an airfoil, but precisely a fbw to deal with the forward swept wing
@50CalChicken Oh man, well I'm glad I was just about to scrap this entire wing design. I took some advice and I'm starting to make the aerofoil first, then put in the actual wings.
@GorillaGuerrilla I do have a system that completely eliminates wing flex, however it would take quite a while to install it on this plane.
@50CalChicken thats gonna be true for real life designs, but the real x-29 survived it tho. maybe someday we gonna see stuff that can deal with the flexing even better
@GorillaGuerrilla true, however, the main problem is that if you want to create a system that greatly improves on standard performance, the wing flex is really going to hurt it.
@50CalChicken it wasnt THAT bad, took me around 20 minutes to add a fbw system and calibrate.
i added a fbw system to it, and fixed some minor problems. i left a large portion of the plane for you to experiment with so i dont take away all the fun of fixing it oh, don't bother with using the flaps. i dont think the plnae need extra lift. unless u gonna ask me again i will fix it with other ways. adding flaps do mess with the handling abit
I have tried to fix it and I must say the design is fundamentally screwed
so this is a x29, i would fix that lol
first thing first, your flight computer is pointed backwards.
@TRD6932 it doesn't lift. It can take off, the main issue is the fact that it immediately tries to nose dive. And it does, but then tries to turn out of it by pitching down (the stick would be going forward instead of facing the pilot) I'm yet to check the CoL and CoM, but it may have something to do how the aircraft generates lift.
