actually doing it by the videos was a piece of cake. I am semi bad at soldering, but I did my Hobbywing mg995 with ease - 10 minutes and they were done, the biggest issues was making certain I would not later on confuse them with my normal direction servos. Note: this may not work on all Traxxas servos. The internals are not wired, they are merely soldered in contact via close proximation. But yea if the radio supports channel mixing. . . .
