Comments: Good high resolution servos. Gear trains sometimes have "gritty" spots due to tight gear mesh but the gears will break in and smooth out after a few dozen flights. If your radio system has any jitter in the PWM signal these servos will try to move in response to it and will jitter and buzz. This can be eliminated by raising the deadband slightly higher than the jitter so the servo ignores it (this is the fault of the radio system not the servo) Hyperion doesn't sell cases for these but you can use an Airtronics 94842 case (both servos are made by the same manufacturer)

Comments: I installed 3 of these a cylic servos on my T-Rex 600E pro, and couldn't be happier. They have heaps of torque, perform flawlessly and the price is excellent! Highly recommended!

Comments: Installed easily, performance is excellent, super fast, lots of torque. outperforms my previous "best" servo (ACE DS1313) with ease. At about half the price of comparable servos from other companies, I'm for sure going to buy more!
