I really love this design, but no matter what tweaks i make I cant get it to fly properly. Ive manipulated the COM, COT, and COL as much as i could and it will not fly properly regardless of what I do, please help!

    @Kerrak I did everything I could, short of adding servos to give it thrust vectoring, or changing wing/engine angles. :\
    .
    It at least flies now in a kinda-sorta stable way, so long as you don't look at it too funny... But hoo-boy does it have considerable nose-down (in part due to having a couple dead sumo wrestlers packed into the nose-cone...). which I just couldn't rectumfry unfortunately :(

    What I'm finding is that it mainly has too low of a lifting area.
    I've added internal (mostly hidden completely from view) wings and it flies now, but it is oh-so-horribly sluggish to respond, and under just the turbo-fans, barely wants to go anywhere.
    .
    It also seems to have quite a high stall speed, which makes any serious attempts at climbing rather difficult...
    .
    I'm just trying to work out the responsiveness at the moment though.
    I DO have a really nifty visual glitch happening with my designer view, which sadly doesn't get captured in a screenshot. It's basically like X-Ray Mode except everything is colored (so it looks really cool) paired with a "Clipping" effect (which ruins the coolness of the x-ray heh).
    .
    EDIT: Oh... derp. The turbofans aren't the ones that are enabled by default... hahah GG me :} That sure does explain why changing their power scalar isn't impacting speed at all!

    @Formula350 thanks! I built another similar plane ground up and found that hiding a jet in the front helped stability tremendously

    TWO HUNDRED
    and SIXTY EIGHT
    BILLION
    Gallons of fuel?!?!? lmao
    .
    That's some impressive Quantum Storage fuel tanks you've got goin on, given it only ends up weighing 35,500lbs!
    Anyways I'm no expert but having just gone through all that with what I uploaded last night, I'll see if I can figure something out heh If not through normal UI accessible stuff, then with using Overload mod... fingers crossed

    @iniMiiW thank you my man, I’ve gotten it flying a few times, but it starts spinning in circles… like a car doing a donut in midair. The engines are in AG 12&4 btw, but the main one should be totally sufficient for its weight. Also AG4 +vtol =surprise

    I can't fix this, but quite possibly others so I've spotlighted it :)
