Thank you !!!
I think you're right ...
I disabled the other two controllers BEC.
I'll check and I'll update the thread

I use this servo: http://www.hobbyking.com/hobbyking/s...idProduct=8761.
The servo worked fine with the HobbyKing Multi-Rotor Control Board V2.1.
Thank you
Besides the BEC being disabled on #2-8, make sure ch4 is set to servo and not esc.

I have a Hitec HS-5085MG digital servo coming so I'll give that a try and see how well it works for the yaw.

So far it seems that the "jitter" and other problems are user errors.
It can happen. There are alot of things to remember and configure.
Is the board , or programming at fault?
It hasn't been shown to be.

Nobody I've heard of has shelled out 50$+ yet for a quality digital micro servo. I've read only one case where a budget digital worked. Kk himself said there is an issue where sub quality servos may not work. So yes, its a problem with the board.

hrm...wasn't even a $50 servo either.
I guess someone's not paying attention in their own thread.

If you're not trying to sort this problem out 1st hand yourself then you clearly have no experience or constructive advice to pass on.
Out.

I bought a decent, quality servo so once it gets in, I can test it out. Patience grasshopper!
Also, why does it have to be $50+?

It dosent, but most of the brand name fastest digital servos are around that range which is what is supposed to work with this board in it's current config.

I'll try out the Hitec HS-5085 next week when it comes in. I'll try to get a video with the HS-85MG and the HS-5085MG to show a difference.

What board isolation solutions have been tried, and failed or succeeded?
