Besiege Fast Rocket-Powered Flying Sled
Please note that this post is over a year old and may contain outdated information.
A fast rocket-powered sled that can also fly and take quite a beating. Uses plows for low-friction movement along the ground and vertical rockets to allow for fly with a decent level of control.
Uses [F][C][V][B] keys for forward, backward, and side-to-side movement. Numpad  is an additional forward rocket for super fast forward speed. Numpad  and  rotate the sled. Numpad  controls vertical hover rockets and numpad [+] controls secondary vertical rockets.
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.
