sweeping with a spektrum linear server

Hey! What is that yellow thing you have the servo plugged in to?

Heli tests 100% working before I unplugged it's servos. I tested 2 separate outputs on the heli's board to my last brand new servo, nada. Identical servos to what's on the heli used to control the collective.

I plug in my new servo and nada, I plug known good heli servo into arduino ( just signal, power wires go to lipoly) and nothing, no jitter, no movement at all.

I plug heli servo back into servo and heli works 100%

The yellow thing is just an extender ( I think? ) I tested the pinout with my multimeter and the pins are the same. ( orange on servo is orange on extender, black is black, brown is brown )

I'm going to take the last servo, ( the one never plugged into arduino power ) to the hobby shop and have them test it.

I do not know if this has anything to do with your issues, but the yellow piece is not an extender.
It has a chip in it that reverses the servo.

Great.

I'll pull that out and make a new thing to plug it in to.

also.

Hazah!

Not sure if it was the 'reverser' I had on there or the missing ground, but it WORKS !!

Thank you all.
