RE: Hitec 7955tg servos junk
I am a retired Aerospace test engineer. In 2005 I was hired by RCU to test the best servos for a review.
I completed the tests. They were not published by RCU but they paid me for my work.
At the time the premier Hitec servo was the 5955 rated at 330 oz/in. I could barely get 200 oz/in out of it. Other than that it was a very impressive servo with titanium gears and a tight deadband.
The JR servos I tested would generally produce the advertised torque but would burn out quickly if loaded to their rated torque. Fortunately there was no practical way you could get to the rated torque.
I have the torque curves of the tests if you are interested. They are somewhat dated now.
