I just have a couple quick questions here.Are the factory pinion gears on the NEMESIS 17/21?My other question is about servos.Over the years I have went thruogh a few and put new gear sets in a couple.My question is do you think it is worth it to put a new gear set in a servo?On the NEMESIS,it usually strips the metal gears after a while with the servo motor still good.I would hate to replace the gearset to have the motor burn out the next day.Just would like to hear some of your opinions on weather you think its worth it or not to do the gearset or buy a new servo.
