Northrop Grumman X-47B

After many hours, an attempt at an X-47B replica. Very close in size, shape, and weight of the original and performance-wise it should be close as well. Cruise speed around 690 mph at 60% throttle. Since we don't have automatic stability control, I had to fake it a little using airbrakes. Yaw controls the inner airbrake on each wing, go easy with it, if the plane starts to rock back and fourth, you need to gently apply yaw in opposite direction to straighten it back out. It's actually quite fun once you get used to it. We also don't have control surfaces as activation groups yet, so VTOL controls the outer airbrakes for drag flaps, anything under %50 throttle or so, you should have them deployed at about the 3/4 position. Landing is a bit of a challenge as well, come in around %15 throttle with flaps at the 3/4 position, keep it straight, and cut throttle and full flaps right as you are about to touch down. Slowing down too much in the air on approach makes it hard to control. (Again, where is that stability control devs?) :) I know it isn't as pretty as it could be but it took enough XML modding to get it where it is and I was focused more on scale and performance. I also hate the intakes where they are, I wish we had hollow tubes for fuselage parts. Eventually I might try and make it prettier but for now, this will do. Have fun!

    Its looks nice but the speed and handling is the main issue I found myself with

    Very nice! I tried to make something similar a while back but it turned out hugely different than I had intended, regardless, drones are cool! And yours is no exception
