May 8, 2013Application(s): I installed two of these servo's on elevators on my FeiBao L-39 jet.
Comments: I'm in doubt to exchange them for other brand and type before I make the first flight!. They have a lot of play on the gear train.... so much that i'm afraid they will cause the elevators to flutter!
Used other DES servo's in the past and was always satisfied with performance up until I bought these...
