Thought I'd post a footnote citing that the speed throttles on the Wrangler. An odd move to increase both potential speed and efficiency.

Any case, you may want to hit P if you're not relying on extreme volumes of speed. Simply put this locks the automatic afterburner, which otherwise will kick in after several seconds of uninterupted forward flight. This is indicate by a green light on the wrangler's boots.

Past that, the revolvers are modular, having tank gun, bullet, and mortar modes you can toggle per gun using Numpads 1 and 3 for bullet, and 4 and 6 for mortars. This also changes the front sight on the guns for some cool looking indication.
