So, I tried it out in Single player for a while, and it's kinda meh. The directional control is the best from the jetpacks I've seen the server use, it's nearly pinpoint. You can actually dodge shots, and the combat seems like it would be much improved. On a negative note though, the vertical lift is horrendous. Takes way too long to gain upward momentum, and you fall like a rock even when trying to slow your fall. On a more positive note, the addition of a specific jump pack (jetpack but with 1/10th the fuel) is a really interesting idea, and would be nice to have in events where GMs don't want us flying all over the place.
Overall, I like the feel, and if the drag can be edited, it would be a big improvement from a player's perspective. I doubt this suggestion will go anywhere, though, as this is too similar to the existing jetpacks, unless they are less resource intensive than the current jetpacks (I'm not that good with the technical aspects of the jetpacks, but they feel almost identical to the current ones, so I'm guessing they're designed similarly).
