    Sturdy structure... I like the control arm, all metal, solid... beautiful. However, when I connect it to my servo tester... I can only control the lens about 90 degrees... maybe it needs an extended pwm input..... (less than, greater than 1 to 2 milliseconds ???) (The tester's operating voltage is 4.8 volts...) It is heavy, so it is not so much for the aircraft, but for the vehicle/land ship ...may be good. Fortunately my application is very happy with the 90 degree release, so I will keep them...

    The modification/specification is a mixed package...so I bought it (actually 2) and when I go buy it, it doesn't fall at all. Assembly of the frontal collision tower........Nothing I can't fix with a utility knife, flat files and dremel tools. Now I have it.........it works fine. I don't have the problem of bringing it together as mentioned in other comments. It is installed in a 2wd Stampede with an RTR Titan engine and an XL5 ESC. (Note: You need another screw to connect the servo protector... but if you have been using it in the RC for 5 minutes, you may already have spare parts).

    So good so far, it seems to be waterproof, as they say. I hope it last's.

    I bought this replacement for my 2wd bar. The engine was out of repair after a month and it is likely to be on the track with him. Do not trust these steering gears. Question 1: When I disarmed, I found the rubber seal that came with the servo system. This may cause him to fail in a few days.

    When driving trails and rocks on my Traxxas TRX4, the sturdy steering gear can handle it well. I bought this update as an administrative trouble I have. It is directly installed in its position without any modification to the mounting bracket, which is an advantage. However, compared to the Traxxas, the cable is about 3 inches shorter, so I had to extend it by 3 inches. It has torque through some key turns. It is slightly heavier than the standard steering servo system, which is another advantage of rock crawling. The alloy steering pinion assembly is durable. I noticed that it did not return exactly to the "zero" position. Therefore, when traveling in a straight line, even after adjusting the servo, it is not always straight. Tracking rock, this is no big deal. For the sake of accuracy, it is not the best. So I attracted a star from it. For the explosion of money, this is worth it.

    Most reviews are for use of this servo for RC vehicles which is it's primary use. I purchased it for a automation/robotics project. My testing show it is quite powerful and moves fast enough for my application (a gripper or hand). Although heavier than some plastic servos I've tested that is ok considering the greater strength. As for reliability, time will tell. I will try to give an update in the future.
