IGOS For sure any servo produce torque. No matter if it is linear or rotary. Since you have an apllied force and an arm, bingo, here you have a torque.
Not true. Torque is a ROTARY force at a specific distance. It is the product of force x the length of the arm. Hence the units - foot pounds or inch ounces. When the distance is specified then you can calculate the force. Linear servos produce a LINEAR force. It is just a force in pounds or ounces. Within reason the distance of the arm does not matter. On linear servos you can attach the pushrod anywhere on the servo arm and you will always get the same force.
Dear HK, please some more info about the 3 extra gear wheels on the opposite side of the motor gear. Also what's the difference, except for the gearing, with the other micro linear servo's cause specs are the same.
Interesting
The gearing is probably used to turn a rotary potentiometer for feedback.
Heck knows why another linear servo. Extra gears will make placement even more difficult. More gears to fail with dust. And it is heavy. Yikes!
Yes, the middle- and right gear wheel drive the little pot. But why? The other micro linear servo's work without it... What the combination of the left and middle gear wheel do is an even bigger mystery.
MegaTesla, you are right, these extra gears are for drive the potentiometer ... so for have a feedback about the servo position. It is looking a terrible design: more heavy, more parts that can brake, and if in pin of the gear shift over another, the center position is lost
It is Enough strong and reliable device. No problems with he do not see. Much lung

I bought three and when I first plugged them into the orange micro receiver and a Hobby King XP 3A 1S ESC with a 350mAh 1S LiPo, they all stuck at some point on their travel. Two finally freed up but the other still has issues. I got a little Vaseline on a toothpick and put it on the gears of all and they all worked better but the one still bound up and none had much torque to push the control horns. I'm now ordering the HK-5320 Ultra-Micro Digital Servo to replace these. I believe the binding is due to so many gears being used to actuate the pot for this servo. It was worth a try anyway.
