For all you that are controlling the pan and tilt of your cameras with a transmitter stick is there some way to make it so when you release the stick that the camera stays at its last known position instead of just returning to center?

Does that make sense? I'm sure there has to be something cheap that you can just put between the rx and the servo to ix this problem.

I've done a search and haven't found anything though...

Thanks for your help,

Brian

You can do this of course several ways. One is to use standard servos that already center themselves when stick goes back to zero. Of course the design must allow for a lot of travel or you will have only a limited pan/tilt, but this is the simplest. There are a few open source designs out there for 360 travel servos that return to a "center" as well - take a look through the robotic forums. IMO return to center is not necessary, nor is having 360 always the solution. Would I be incorrect to guess you are trying to do this solo? If so, you REALLY don't need to focus on a camera in flight, and what direction it's pointing. Use the heli to do that and preset the camera so that it points where you want it to before liftoff.

I will not be flying solo. My plan is to have another spektrum tx/rx control the pan/tilt and the shutter. This will be my camera man.

My question is that I don't want the camera man to have to hold the tx stick in a specific orientation for several minutes while taking a shot. I just want it to be able to move it to the desired location and let go of the stick and have the camera stay where it's at instead of returning back to center.

Does that make sense?

I'm not sure about all this 360 stuff???

And I'm using hitec servos

You can add gyros for position hold or take the spring out of your tx.

We've found using 360 servos to be the easiest.

Search around and you will see 'how to' threads on modifying servos for continuous rotation...

Or purchase '360' servos..servo city is a good source.

When in doubt...auto out

Brian,
I think you will need something like this for decent mount control;
INS-1 Speciality gyro for camera mount stabilisation Availability TBA. From spartan-rc.
Or a camera mount slew control and stabilization unit from CARVEC.
Cheers,
Ahmet

I saw this a while back, I've never heard reviews of how it actually works.

The concept you describe is rather common place and without any gyros or exotic equipment. All my camera mounts do this by way of 360 deg servos just as 500D and Ifly described. Servos are plugged directly into the receiver, nothing in-between. I use a rather old Futaba 7 chnl TX for camera mount pan & tilt (well my camera operator uses it) and the sticks just position the camera, let go and the servos stop at their location til you move the sticks again. I've put tilt on elevator and pan on ailerons for a one stick operation but have also used tilt on throttle channel to keep interaction down between the functions. It's kind of user preference.

Good luck.

Spartan RC Vision-Lock if you can find them. They are no longer offered, but surface from time-to-time on RR.
