I am a die hard JR user and have been since 1980, when the Futaba J took a dump on my pristine Arrow.
Horizon's service has been outstanding, often replacing components for free. I'll never forget the fact that they replaced my broken Webra 145 sent it for service with a brand new W160 at N/C.

Yet, i've played with other servos, both, certain Futabas,Hi Techsand Spektrums, and most recently a couple medium/small sized Savox. I always come back to JR servos. To me, they have proven to be most reliable over the decades

As far as Hobby King, forgetaboutit. Never again
