KST X12-508 Micro Digital Metal Gear Servo
I ordered 3 of these servos to replace the stock servos on my Align Trex 470. Within the first 4 flights the servos developed slope and play in the gears that would give me issues on the pitch for the main blades. The KST are rock solid, no play at all. Highly recommended.
