This is my original set of BK SERVO’S, bought these as soon as they were released. I just put my 600th flight on these Servo’s. They have been in 4 different Heli’s, been through 30 crashes and still perform perfectly. Absolutely no slop, never stripped a gear, just awesomeness. Thank BK SERVO for the support and the best Servo’s on the market with the best customer service in the industry.

BK Servos are by far the smoothest and fastest servo I have ever used. Not only does BK Servos keep me looking good in the pits, but the quick response keeps me one step ahead of the competition.
