I have seen comments that certain servos do not work with certain receivers but it sems to be a rare issue. In general, servos do not seem to care what kind of receiver they are connected to.

Hi,

I have seen comments that certain servos do not work with certain receivers but it sems to be a rare issue. In general, servos do not seem to care what kind of receiver they are connected to.
Correct. Very rare....

BUT I have seen with my eyes that a certain type of digital servo of JR did NOT work with a Futaba PCM receiver. The fenomen with those JR-servo's : jitter and nothing else.
This was on a friend's large soarer (5.5 meter, about 220 inches). I cannot remember which type of JR digital servo it was. I can ask him if you want.
He called me to check that problem with 3 same servo's and same problem. We did test with other servos, other receivers, other batteries. Finally he returned this expensive servo's back to the retailer and bought Futaba servo's I guess.

Oliver, I it wouldn't be to much of a hassle, could you find out what servos those were?

Thanks,
Doug

My buddy who's previously been an all Futaba guy just finished a Yak and used all JR digital servos, both the 8411's and the 8611A's, with the Futaba 149 PCM receiver. It all works great. Futaba will tell you that they don't guarantee their stuff will work with other manufacturers equipment, but servos don't really seem to care what kind of receiver they are connected to.

There are those rare circumstances though where something is amiss. I don't think you'd have a problem with frying them, more than likely if there was a problem it would be something of a jitter type problem if it happened. Perhaps you might consider buying just one to try out first?

The servo's get an analog signal from the reciever after the position is decoded. They don't know or care what they are hooked up to.
