A quick and dirty AC camera stabilization setup
FPV Tilt Camera Mount with Landing Gear
I saw one of these a few weeks back, and got to thinking...
How can I easily mount this to a stock AC without making any drastic mods, getting the CG close, and having tilt and roll stabilization possible?
This is what I came up with...going to see if it will take off in the morning.
Mechanically, the pieces are in the right places. It moves well. It's probably not super robust, but we'll see if it gets the job done.
Three metal pieces bent for the roll hinge with nylon washers.
Easystar rudder horn, control rod and clamp.
Random thumbscrew from Ace that clamps into an alum. bar underneath the two plys of balsa and squeezes the fiber frame. Pretty secure actually.
The kit was $20. I got it as a weight filler with a 9x from Hobby King. The rest is scrap.
It at least gets the concept going cheaply, we'll see how long it lasts.
Here's the battery outrigger from previous static camera setup.
Ideas for improvements are always appreciated...

Please let us know how you get on John. I purchased the very same mount for the very same reason ! Weight filler for 9x from Hobbyking. I haven't bothered to build it yet but if you have success I might make it my next project.

I ordered one his morning. just for camera mount, I hope it works as well as yours, for $19 it was worth a test.

Well, the AC can pick it all up. Definitely needs some tuning, maybe just moving the battery to the other side of the rail. Uploading video now.
I'm running the ACM code out of the SVN....I'm wondering what my best code option is to get the stabilization actually working? I'll take a look at the pirates code and see.

Right now The camera control will output pitch on CH 6 out and Roll on channel 5.

@Jason
what if we are running an Hexa? Is camera control incompatible with hexa quads?

I got the roll working on CH_6, just had to multiply by a -1 to reverse the servo.
Add: "ENABLE_CAM 1" to APM_Config.hThis is the chunk to reverse if need be.g.rc_camera_roll.radio_out);g.rc_camera_roll.servo_out = dcm.roll_sensor * -1;
g.rc_camera_roll.calc_pwm();
APM_RC.OutputCh(CH_6, g.rc_camera_roll.radio_out);Good question on the hexa, I saw the big red X on CH8.

Roll and Pitch work great. Should be able to get it in the air in the morning.

Any Channel can be an output channel, even channel 8. Just don't use channel 8 as an input.
