So I just finished rewireing my mastodon and since there arent any guides yet I'd atleast give people a starting point. First things first the shell is lightly solvent welded togeather so you'll have to take a knife or flat head screw driver and carefully pry at areas that sick whe you try to butterfly it open. Mine didnt seem to be too heavily glued so it didnt take much force to get the shell appart. After taking a look at the internals for a little bit I was able to figure out that it basically just has rapidstrike internals but with a much bigger pusher mech. As such it is gonna be the exact same wiring as a rapid strike with pusher retraction so instead of making a wiring diagram I am just gonna link to BSUK's http://m.imgur.com/IbI1lG7?r
As far as taking out the extra guff every motor has a small ciruit board on it if you just heat up the terminals of the motors with a soldering iron they should just slip off the motors without causing any trouble. The thermistor is located on the positive terminal of the battery tray. To get to it you do have to remove the pusher mech since it is on the bottom of the tray. All the switches except the one closest to the pusher motor and the ones in the handle are safetys. Heres of picture of the one closer to the motor as reference.

This is the switch that controls the pusher retraction and I kept it as the stock switch because I wasnt sure how to mount a replacement switch. If you plan on doing the same the white wire corrosponds to 1 in the diagram the blue corrosponds to 2 and the black corrosponds to 3. The picture below is what the internals look like after the rewire.
I am currently running it off a 3s lipo and it hasnt had a problem yet. It seems a bit stronger then stock but I dont have a chrono graph. If you guys have any questions on something I might have missed feel free to ask and I hope this helps.
