Hc3sx and align 610 servos ?

[Dennis Everett]

Hi , is there any known issues between align 610 servos and the hc unit ? A friend just got one and when you plug in the servos , they twitch and jump around , elevator being the worst , he then plugged the servos into a receiver , quiet as can be , tail servo (align ds650) works perfect with the hc unit , they lowered the head gain , no help , also doesn't do it all the time , any ideas on whats wrong ? they were able to fly the heli (align 700) and when not head bobbleing , flew great , any and all ideas welcome , thanks .. Dennis

Check the frame rate. It has to be at 11 milliseconds.

I still have the 610's with a HC3SX on my TRex 700 and have never had the slightest problem with them.

ive two 700 helis with 610/s and one with sats ,jitters quite a bit more than the one with the reicever,but boyh are fine in the air.

Mine does it as well. But it flies great and there are no problems. I did try the 3gx at first and if I remember correctly the servos did the same. Doesn't seem to affect anything.

I've never had any problems using align 610 or 615 on cyclic (never tried/used an Align tail servo) as long as I used an external Rx (Spektrum in my case). Even with a good 20amp ubec I could never get them to work well on a sats-only setup.

My gut-feeling is that while there is nothing wrong with Align 610/615 cyclic servos, they may be a bit too peak-amp hungry for a sats-only setup, esp when you fly your heli med-hard 3D and/or have poor collective management skills like me, lol!)..
