Heavy Duty Pan and Tilt

| Mounted on my big Talon |
Introduction
After buying and building several Pan and Tilt set-ups I got tired of how cheaply the purchased ones were and how flimsy they all were. The biggest problem has alwys been the pan axis is simply never robust enough.
When I decided to put together a pan set-up for my big Talon to carry a 2 axis brushless gimbal, I went looking for components that I could buy to build a stout pan mechanism and I found the components in a company called Actobotics.
With their servo coupler and bearing plate I was able to build on a 3D printed servo mount, a raised bearing that made the servo connection very strong. This structure kept all the pressure off the servo shaft and its bearings.

I've added to this a turret and tilt mechanism which I have modified many times.
Tilt Configurations
Because I always seem to need something different for every plane I've ended up with several versions of this idea. Most of my planes only require the ability to look down and around so there are three different camera mount plates.
- Standard Modius/Runcam mount
- Dual Camera Mounted
- Misc Camera mount
Added to this I have made two different height turrets, one for the three mounts above and one for a tilt which looks both up (19 deg) and down (-42 deg). This one also has a over-under camera mount for a Mobius/Runcam and an HS1177 camera. This one should work well in a head tracking set-up.

Deck Configurations
I designed three different ways to mount it to a deck. The first deck plate which incorporates the bearing mount puts most of the unit below the deck.

The second deck plate replaces the servo mount and puts the tilt mechanism up higher. This would be used when you don't have a lot of depth under the deck.

The last method is to simply drill the planes deck to fit around the standard servo bracket.
