    Application(s): Trex 500 and 500pro

    Comments: I found a lot of problems people have with this and other tail servos is people setting them to the new standard for a tail 333mhz. This servo is rated at a max of 300 from the manufacturer. I had mine set on the pro to 290 and never had a issue until I had a rekit crash. It then developed a tick. I have been running one on my Airwolf for over a year and a half with a Futaba 401 without any issues. The only problem I have is no replacement gears.
