I have resurrected the Flyrace for 0.5.1 (from 1.2.1 by Dani/Landil). I have modified it so it doesnt use teleporter tiles anymore, so that it is a real CTF map. I did not want it to be running as a mod because I think this map is interesting for beginners, to learn how to use the hook and move.
Changes: no more teleporter tiles, non-hookable tiles are now 0.5x non-hookable tiles, lava in middle replaced by spikes, to go to the other base, you can cross the middle in the upper section (two passages, upper passage has the unique katana, other katanas removed), and flags have been put back to their logical base (blue flag on blue side, red flag on red side). All editing done by Ubuntu on my request.
I am currently hosting it (search for flyrace) and I don't know how long I will keep the server up (maybe one or two weeks, I don't know after). If you want to host it feel free to get the map from my server. I have changed the collision sensitivity of death tiles very little because it was too sentitive. I will commit the patch to the 0.5.x SVN branch of teeworlds (official branch) later (maybe tonight), and this sensitivity will be the default one in 0.6.0 when it is released.
Also, I host the map for beginners. I might as well say here that I ban teamhookers/teamkillers systematically, and players misbehaving or who ruin the game because they're not beginners anymore will be banned too. My only goal with hosting the map is helping new players, I think it's a great tutorial on how to gain momentum with the hook and managing the double jump.
