You will need an output that you can use as a pass-through to assign the transmitter channel to both the flight controller and the gimbal control.
Dunno if the MK can be configured for this...

Could a manual tilt be done with a Naza FC / Futaba S-Bus receiver?

Hi Jussi,
Never a doubt that a gimbal like this would be of interest to many!
You made the RCG front page as a HOT thread

Cheers,

Thanks, Jim

I did see it. Last time that happened was when we released the AQ and ESC32...

How is the AQ coming along? Gonna show some video soon?

Best

Ya, this thing has to be hot if RCG says so!

Won't the signals transferred from the mk fc be able to override the signals from controller?

I was thinking of connecting like shown in the attachment.

The wiring with my setup today with regular servoes is basicly the same - just bypass the controllerboard and connect directly to servoes instead of the BL motors..

Yep, Robin - in theory this should work. But only Jussi can tell atm.
Unfortunetely I can't test it for you.

I'm pretty sure Jussi will provide us with some more info soon.
Once the storm has calmed down...


Edit: need to elaborate the above a bit.

When you connect the output of the FC, the internal stabilization takes affect.
Means you'll have the signals of the stabi sensors on the feed for the cam controller.
They simply will fight each other. (That's where the GUI kicks in to adjust these influences.)

For a pass-through of the override channel (usually an AUX on a jog dial or knob of the transmitter) you need to eliminate or at least dampen the influence of the FCs sensors - unless this is a wanted effect.

Example: through the POI function of the AutoQuad you can point your camera at a desired coordinate.
If we combine it with the stabilization of the stand-alone controller we can
- free the FC from doing the stabi job
- overlay the camera controller with GPS based functionality

That'll be a feature every AV artist will be licking his fingers for...

I'd also be interested in this. Nick control through MK board, for reasons of my own other than the standard 1 or two man operation.

Sure guys, me too!

If you have a button in the MK tools where you say "sensors shut up" to only use the override ... why not.

Not sure if you can tell the MK "your a gimbal port but please do nothing, just listen to my command"?


Ooops: you obviously missed my "Edit"...

The controller can utilize two types of input:

Direct RX connection, either passed through your FC or from an extra free channel or from a seperate RX. There is two channels (axises) that can be controlled in the current version.

There is also a 360 function in the making, that will allow to use a channel to control a continous pan/tilt/roll rate proportional to the stick deflection in either direction.

The controller can also take the pitch/roll gimbal output from your FC - it uses this to know the attitude of the frame, this is used to lock in the stabilisation further for fast moves and looking down angles and involves a calibration procedure (a simple one)

But it can be used standalone - that was what we did in the videos.

Man I love the activity with this it just kind of exploded over the past week. I can't wait to get a board and tinker with gimbal ideas. Excited to see people's ideas for a canon 5d gimbal.
