I'm mad as hell! My $139 DS8717 servo on my elevator control just quit working AFTER 2 FLIGHTS! The motor cooked. I pulled off the back cover, and it smelled like burnt silicon. I thought these servos were supposed to be the cat's ass! WTF? Anybody else have a similar problem? I have money but not enough to waste on servos every 2 flights.

how much power you feeding it? you regulated?
those are great servos and no they don't just "fry" unless it was defective from the factory.
or unless you have too much power going to it.

I am running 6.8V regulated with the REACTOR X. The other 2 servos are fine. I guess I got a bad one....SUCKS!

No DS8717s in Japan!
I guess JR only makes DS8717s for North America. The local hobby shops here in Japan doesn't carry them. They have 8715s which seem to be the same specs as the DS8717s. I guess I'll buy a 8715 so I don't have to wait for mail order.

8915 and 8717 are the same. the german version is DS8922

Send it back to the USA or to Horizon, I am sure you get your money back.

Greetings

Check your voltage coming out of your regulator. If its good the servo was defective.

Do what has to be done
