## Questions & Answers

**Q: Can these be run at a higher pwm frequency than 50hz?  ideally i'd like to run them at 200hz.**
A: No need to think about that. These Micro Servos are not reliable. I had on fail (sticks) on me during preflight so I switched it from the elevator to rudder. Then on the next flight the elevator servo and one aileron servo failed in flight. Was lucky to get help from an experienced RC plane flyer who was helping me with the test flights. Will not buy again

## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice tiny servos
*by S***H on October 5, 2024*

This is a nice set of these small servos that work well for my proof of concept project. They aren't super powerful, but not advertised as such, but they'll do the job for a project you might be planning that needs many multiple servos to work. I hooked one up to a servo controller and it worked well and was very quiet. 180 degrees of movement which will work fine for my project ahead. If you need a bunch of little plastic geared servos, this is a great assortment that will give you 10 of them. I'm very satisfied with the purchase. Just as advertised.

### ⭐⭐⭐⭐⭐ Good value for the quality and price point
*by B***K on May 12, 2019*

Rating is based on value. These are inexpensive plastic servos and likely will not withstand long term heavy use, but that is not what these servos are for. In the right application, I am sure they will be fine. Expectations need to be adjusted accordingly.The motors all worked as delivered, just be aware of differences in the behavior from one instance to another. Range of motion and precision was somewhat inconsistent. Detailed electrical, mechanical, and performance specifications would be nice to have.All connectors and wires were properly terminated and worked fine. Screws and servo horns were useful.Durability is not rated since that is a function of time and duty cycle.Overall, decent value but would not pay more. They are right at the edge of being over priced.

### ⭐⭐⭐⭐⭐ Great servos for Sky Surfer X8 Model RC plane
*by Z***N on February 17, 2024*

I used these on my first fixed-wing build, a Sky Surfer X8. The servos fit perfectly, and worked just fine on the first attempt. They have lasted at least 10 flights so far with no issues running on my 3S battery setup with an X8R Frsky receiver. Can't beat the price, plus you get some spares incase one does go bad.
