    Application(s): i used it as tail servo for my 30size hirobo Scale Lama... i use 2s lipo pack for my rx with a 6v regulator output.. Sadly, after hovering (3ft) a mimute or so, this servo gave up.. Tail spins up on one side causing me to flick the throttle cut switch. So lucky i did'nt crash my precious Lama .. Lol!!? When i check.the servo, it was too hot, not only warm but damn hot and gears all locked up.. So i was thinking if this sevo really can do the job at 6v.

    Comments: i expected more great performance on this servo....but i got less.
