Xpert KD1 Cyclic Metal Gear Brushless Servo (High Voltage)
Purchased this combo kd1 + kd1t.

cons:
1. fist of all they (expert) changed specs on kd1t - previously they stated it has 15kg torque, but when I received it, on the box was described 7.5kg, after my complaints to 'amain' they updated their description... don't know when smth get wrong.
2. servo horns are terrible, they bent under low load from my finger, one even cracked on the initial setup. I really don't believe it can handle 30kg torque
3. after about 50 flies, I have noticed little play
4. I am almost unable to notice any difference between cheap align 610 that I had before with this servos...
5. They are expensive

pros:
1. wire management is awesome, you can install servo and then insert your wires
2. they look cool
3. they are silent!!!
4. I believe they are precise and probably has a lot of torque, nobody can confirm it...

5 stars, fast and torquey. If my fingers were as fast they'd be even better!

These are simply the best servos I have ever used in a helicopter. The days of repairing gears is gone due to the servo's over-current and over-voltage protection circuitry. Wire management is easier due to the different wire lengths that simply plug in to the servo and are competently held in place by a rubber boot. Response off center is noticeably fast and smooth. Simply put: these servos are the bomb! I love them!
