Any recommendations for Emax "next strongest" service. Always had good luck with them. All their 12g seem to be of the same torque, just metal gears. Looks like 17g is the next... but there are so many derivatives, it's hard to know which is best. I am thinking I will try metal gears this time around.
The key is metal gear. Something to remember, back in the day a full sized servo had a torque of about 23oz per inch. These days most micro servos are more then that. I use savox metal gear 11g servos for a more robust servo personally.
