RE: how to mount a mini board camera
Peter,
I wanted to use a flexible standoff because there were surface mount components on the back side of the CCD camera. I used fuel tubing and it also offered a bit of shock mounting.
My wife was going to Walmart the night before the first flight and I asked her to get me some big rubber bands. This was what I got. I joined three and stretched them out pretty good. I used new bands every time just in case some nitro got on them. It was mounted on a Cub for the first few flights to work out any kinks, so I figured a rubber band on each side would be enough. I will get some larger single rubber bands and use at least 4. I didn't want too much tension because I wanted as little vibration transfer as possible from the airframe. Hence the foam. It isolates the camera from vibration very well and will conform to curves. Protects the covering, too.
I chose the left side of the wing because that was the side that faced me when the plane was on the bench. When I built the Cub last year, I installed the windows in the Cub with screws with the intention to eventually mount a camera inside.
I chose to rotate on one axis to keep things simple. More linkage means more chance for vibration and more parasitic drag. As it is, my setup only required one or two clicks of aileron trim to offset the drag. The cub flew the same as without the camera...floated like a dream. I didn't want to mount the camera on top of either wing to spoil any lift. I will try it on the top center of the wing at some point.
I did have some issues with signal dropout at 1600 feet and at other times lower to the ground, but I attributed it to multipath interference. I ordered a 900 mhz 5 dbi antenna and that should help. The current one on the receiver is probably a 2 dbi at best. I haven't played with the transmitter antenna orientation yet and I did not experience anything that would suggest an interference problem between the plane's receiver and the video transmitter. I am going to buy a CCD board camera like you have. I found the web site.
The video transmitter is in the cabin of the plane because I wanted to keep the camera mount as small as possible. Plus, there was no way (other than the nut on the threaded antenna mount) to attach it to the camera mount. I tried to locate everything on the CG.
One thing I didn't mention in my first post is that everything runs on 12v. I used a Thunder Power 3 cell 1320mah lipo to power the camera and transmitter. Its light and has good power density. I'll weigh the entire setup soon and post.
Obviously, there are many ways to do this camera stuff. I'll take some more pictures of what I have and post as well so you can see how the mount was constructed.
Thanks
