In Response To: Re: Flying the Hawk (Slith) : How are the aerodynamics? : Do you have to fudge anything to actually get it flying? The aero is actually not bad, in forward flight. The problem is with weight and balance in hover-mode. If you did a proper, realistic mass distribution, the CG is quite a ways forward. WAY more forward than the fans. So if you throttle up for takeoff, you'll immediately flip forwards. That means you need some other means, or force, or something, to counteract that forward-pitching moment. That's the ONLY thing I've had to "fudge." I put the CG closer to the "realistic" position (which, coincidentally, is why it flies so well in forward flight), and added some internal "puffers" to give it the torque required to achieve a stable hover. I'll probably make up some fancy story about how the force is generated. ;-) But if flies great, it's a blast!
