Default Compatibility issue with Hitec 56HB servos and FMA M5 receiver

Please share this with your support staff in case other customers call in with this question.

FMA recently discovered a compatibility issue with the Hitec 55 and 56 servos. The problem is with the timing clock of the receivers’ processor. FMA Direct is working on a solution to this issue but are unsure when they will have a fix.

HS-56 HS-56HB HS-55 FMA Direct M5

I do not know if this is an issue with other models of the FMA receiver.

I am using a positive shift Futaba compatible receiver. My transmitter is a Futaba Skysport 6.

I do not know if this also happens with the negative shift JR compatible receiver.

I have had excellent luck with the M5 in another airplane using old Maxx MX30 servos.

The problem is that the servos will act like they are unable to center, constantly jittering. The control arm movement is noticeable but not excessive. The servos are quiet when the transmitter is turned off. FMA has recreated the problem.

Tohm,
I've the same issue. Is it "safe" to fly these like this?

FMA M5
HS-55
Futaba 7CAP

Thanks

Barry

This issue has been addressed with the FMA Direct M5v2 receiver. The problem is that the Hitec 56 use a digital amplifier. The v2 does a better job with this. I have the v2 and the servos no longer growl.
