So is there a recommendation sheet / quick reference for sufficient torque for a servo based on its use?
For example steering 1/10 2wd buggy 150, 1/10 4wd buggy 180, 1/8 2wd buggy 220, 4wd 260 etc... ?
Comparig all these servos and just don't want to go overboard if not needed.

I was re reading my XXXNT manual for my rebuild and it says to use a steering servo with a minimum of 50 oz of TQ, that is the last time I built a kit.
My new servo will have at least twice that much. Servos have come a long way in 15 years.

tekno recommends a servo with a minimum of at least 200oz of tq for there eb410 and et410 and at least 300oz of torque for there 1/8 scale buggy.
