I installed this servo in the tail of my Goblin 500 and Protos 700. Tight gears and lots of torque. Tail feels great with this servo.
What can I say? It works as advertised. I've been a "long" time Futaba pilot and have generally stayed with their equipment 100%, but they are getting increasingly expensive, especially their servos. This is the first non-Futaba servo I've used in "years!" So far, I'm very happy with it. We'll see how it goes in the long run.
