here is version 2 of this map:
http://www.bungie.net/Stats/Reach/FileDetails.aspx?fid=10554987&player=Willko

this update has the respawn times and ammo of weapons changed to match what they were in Halo: CE. vehicle respawn times have been altered from the default values to best suit gameplay(since there were no vehicle respawns in the original Sidewinder). a hole was fixed that could allow players to be stuck outside the intended playable area.

i haven't seen many attempts at a remake of Sidewinder, so i thought i'd give it a go. this remake is pretty bare-bones due to the budget constraints, though given the size of the map, i think this is a forgivable shortcoming. the map is as close to accurate as i could make it with the available pieces and limitations. the map is set up for nearly all gametypes other than invasion.

"BUT WILLKO, WHAT ABOUT THE SCALING!?"
well, that's a very good question. this map is a little bit smaller than sidewinder, but not by much. i tried to scale it by running speed. for instance, in Halo CE's Sidewinder, if you stand with your back against one of the bases and run a straight line for the overshield in the middle of the map, it will take you approx. 40 seconds to reach it. in this remake, if you stand with your back to a base and run a straight line for the overshield, it will take you approx. 33 seconds. unfortunately, the budget just didn't allow for that tiny bit of extension.

overall, this is not a perfect remake, i don't think a perfect remake is possible in Reach, but it's a better remake of Sidewinder than any i've seen attempted so far.
