Another thing if you're curious why enabling glide on fighter doesn't work at all. Is because most fighters don't have glid enabled. There is a fix for this. Joshua on the mod forum took apart the btrl demo, and made an addition to fs2scp called realfight. which is found
here. And download the 1.2 version and not the 1.2B version. The 1.2 version enables glid on all fighters, which is pretty kickass, and gives fighters inertia. The difference between 1.2, and 1.2B is the fact that 1.2B sucks in the fashion that it does not have inertia for fighters, and 1.2 does have inertia. Don't download the older versions. 1.2 is way kickass with the glid enabled for everything that you get to fly along with inertia. Another thing that i wish V incorporated at least into the game was inertia if the fighters by default don't have glide (which they don't), and the fact that it's a space sim.
The only thing special about realfight, is that every ship in the game has boosted speed (to go along with the inertia improvement). This does not seem to change mission balance from my standpoint, and going up against enemies is really about the same, with the minor advantage of me using my fighter's inertia to swing around targets, and using glide to do slow or fast strafing runs on bigger ships.
One more thing while this fixes your glide problem.
Go here because i bet the good lot of you guys there are affected by the low quality explosion problem. It's an easy fix, deals with changing modifying a table file in the fs2 directory for higher quality explosions (i searched the hlpbb looking for that pretty badly and brought it back to daylight because i see a good deal of members screenshots with the **** explosions, and i don't mean the 3d shockwaves).
EDIT: Apparently i can't spell glide correctly after 3 beers (that's quite retarded). It's not much alcohol but it sure kept me from pushing "e" when spelling glide. Anyway try drinking hornsby's hard cider, good stuff.
