Hey everyone, I'm new to the forum, but I've been playing around with modding for a while. I was hoping to get some advice on working on my Stryfe. I've taken all of the physical locks out of it, as well as the initial resistor. I've been planning to take out the resistors attached to the motor itself, though I'm not exactly sure what benefit that will have. If anyone could tell me what that change will do, that would be appreciated. I'm also not sure how many trustfires I should be using. The thing sounds like it's about to explode with 4 so I'm guessing 2 or 3 would be better, though I'm not exactly sure how to go about using those. I can't find any dummy aa's at any store near me. Are they just not a common product sold anymore, or does everyone make them themselves?

EDIT: So I went to go remove the resistors from the motors, as well as practice removing the motors for when my new ones get here... and I can't get the things out of their housing. Is there a special trick to it I'm missing, or are these just jammed in there really well?
