1) If the OM is down, you can't fly, even though you have wings?
2) So you have a damaged right wing. Will you only be able to spiral down to the right, or just fall flat when you jump like any alien?
2."I'm gonna crash!" *hits a wall, loses 1 hp, hops back on its feet, continues strafe jumping*
1.Hopefully something like stamina will be introduced [KoRx jetpack has a battery that works similar, it runs out faster without a reactor, but works without it still]
2. We cannot compare in game speed with something real yet and another thing is - it need be tested first. Not just give some number without testing in game. So now I can't tell you correct max speed.
Max speeds are easy to work out mathematically. Since this is "tremulous2" it will probably use g_speed of 320 as well, unless the engine will use a totally different speed system, which i think this is what you're talking about.
After finding out that g_speed value, we can look at the speed mod, where for example, human running speed modifier is (float) 1.0 therefore it runs at x1 speed of 320 = 320 qups.
