Review by: Roger SandersKST X08H Plus Horizontal Lug Servo - 5.3Kg.cm 0.0
I have used the standard sized XO8 servos without problems. This new "Plus" servo has almost twice the power without being much larger. When they work, they work very well with minimal (but not zero) backlash in the gears.
However, I have had 50% failure rates in these servos. The failure is in the electronics, which suddenly fail to respond at all. The cause of the problem is unclear.
Fortunately, the failures occurred while the servos were being used on the flaps, so the failure did not result in the loss of the aircraft. Due to my experience, I would recommend that you avoid using these servos on critical controls like the elevator where reliability is essential.
