I have ordered a Matrix M125 to put in the Echo 1 SCAR I got from a recent trade, which at the moment is sitting at around 200 fps. Will it burn out the stock motor? Or will I just need to be careful about my rate of fire? Honestly I'm only experienced with modding bolt action sniper rifles, cause they are stupid simple. I have no idea the stresses and limits of a gearbox. Some advice from those who are much more experienced would be greatly appreciated.
