Never tried using an onboard cam myself. Of those I’ve seem I have to say I intend to agree with Fred, they are not very entertaining. However the thought occurs to me that they might have use. think

Would it be possible to have one plane with the cam fitted so that can film another plane while both are airborne? If that were the case then with someone filming from the ground as well you could inter splice between shots from the ground and airborne footage. Cool

Of course, we’re now getting more into the world of film making than flying but perhaps worth a thought given how cheap these cam’s are.

Hey Keith.

Allow me to reply to your question with a video. An awesome video in my opinion.

Ha Ha! Yes, I agree, a very good video. Applaude Applaude

But there are two distinctly different disciplines’ being shown in that little film. think

One, is the exceptional flying skills of the pilot.

Second is the film production. Those cameras are not the sort of thing you can pick up on Ebay for a couple of hundred quid. There’re professional 3CCD cameras.

Although the end credits tell you who was operating the models and the cameras they don’t tell you who did the hardest job of all……. Editing it!
Whoever it was did an excellent job of choreographing the footage to the score. Applaude

Curiously they used a Tricopter for the aerial shots. More steady than a normal heli I suppose. Confused

So if you’re ever thinking of making a video like that Nando, Dream on my friend! Rolling Eyes

ahah!
You've very skeptic Keith! Smile

The camera used on the tricopter is a GoPro Hero HD, around $299 camera.
The same person flying the tricopter made the video edit and it sure did a great job.

As for flying the Yak, well I'm expecting to count with you're flying skills. Smile
I should have my tricopter ready soon, so I'm counting on you. Wink

The tricopter is way more steady and easy to fly than a heli.
In this case he's using a quite simple tricopter build, just with normal electronics and 4 gyros.
It becomes and excellent platform for aerial videos due to it's 2 axis stabilization, I say 2 because the altitude isn't controlled automatically, despite there are some models that do it.

I don’t know how you know what camera was used Nando, but I’d be very surprised if it was a 300 USD cam. think
I’m almost tempted to get one, but if it turned out not to work as well as the images in that Vid. I’d have no way of getting my money back. Wall

When you’ve got your Tricopter working properly, let me know.

(We could film some slow motion crashes, I’m very good at that!!! Very Happy )

You can see how the tricopter was built and the camera used in here:
http://www.rcexplorer.se/projects/tricopter/tricopter.html

Scroll down and you'll see a pic of the GoPro HD cam, it does 720p 60 FPS.

And here is the cam:
http://www.goprocamera.com/index.php?area=2&productid=33

Check here the example videos:
http://www.goprocamera.com/video

Actually now it's cheaper: $259


And there are more for example this one specially made for FPV.

FatShark FS-DH1.
http://www.gowiththeshark.com/FPV_HD_onboard%20recorder_video%20piloting.html
$289

Can do as well 720p 30FPS, includes builtin battery and SD card for on-board recording as well as video out for FPV usage.
And weights 40gr!

How I know this? Well in PT there is a big and active FPV & AP community and I'm always digging out with some more people this informations and videos to share. Smile

Unfortunately in IE seems that this is not very popular. Sad

Just received the PCB's for my tri today, so I'll start soldering them soon.
But if I keep the pace i usually have building stuff I'll be ready around 2012. Sad
