Besiege Rocket VTOL 2 with Reaction Control Wheels
Please note that this post is over a year old and may contain outdated information.
A vertical take-off and landing (VTOL) aircraft built in Besiege. Uses rockets for thrust and reaction control wheels for pitch, yaw, and roll. Maneuverability is very good and it's very fast, but it's difficult to control, as you can see in the video below. It probably needs more fine-tuning of the reaction wheels and better key mapping.
The craft uses [F][C][V][B] keys (poor alternative to WASD) and numpad  and  for pitch, yaw, and roll control. Numpad  controls main rockets (hold) and numpad [+] controls landing/emergency rockets and pads (toggle). Lastly, numpad  and  rotate the main rockets from downward for takeoff/landing to back-facing for forward flight. Don't rotate them too far or they'll burn up the wings.
In the video I'm using the Keep Camera Rotation Mod so the camera follows the vehicle, and RocketMod to give the flame throwers thrust. Learn more about these mods on the Besiege mod forum.
