I spent some time out this morning trying various configs and just getting to know the flight dynamics of the frame/quad that I built. It's the standard 3DR X form quad, with sonar mounts front and back. I also added some foam to the landing gear to see what type of 'landings' it could withstand. Aside from the collet crash (which broke a landing gear) it handed everything quite well. However, mounting anything heavier than the sonar, telemetry or RX [ie, my GoPro Hero 2] is a no go on the mounts as it just throws the balance off too much.

Thanks to share the video. Very well edited. Are you using APM 2.5 board for your quad? Is the sonar sensor external or part of the board?
Thanks for the feedback. Yes, i'm using APM 2.5 in my quad. The sonar i'm using is an external component bought through DIYD and there are inputs on the APM for it. However, I didn't have the sonar attached in this video.
Hi David, thanks for posting the video. It looks like you and I are about at the same point in our 'stress testing' of quads. :-) I'm in Canberra so if you ever get up here feel free to contact me. I'm in Melbourne from time to time as well.
Have a look at my first try with a GoPro on my new 3DR quad I built last month.
Can you tell me which camera you are using on your quad. A few pictures of your quad and the quad parts would be really helpful. I am about to start my project on a quad with onboard camera for surveillance, so I required some assistance. Are you also using APM 2.5?
I'm using a GoPro2 for now. I have a two axis gimble coming for it as well and will post tests using that soon. I am hoping to test it with a Canon G1X which is a much larger camera so not sure if it will work or not.
I do have some photos of my quad posted on Flickr at http://www.flickr.com/photos/dburkey/sets/72157632045204707/
Nicely done Darrell, it's looking quite good - aside from the second landing perhaps. (; But at least your recorded landings are better than mine. Where's the dramatic tumble?!! (; I love the area you were flying in! Spending all this time in capital cities is doing my head in - if the offer to flying in that paddock of yours exists I might just have to take you up on it! (:
How did you attach the GoPro to the quad and do you still have the gopro protective casing on? It looked a little set back from where I had mine, do you have a picture of that?
There are some pics on my Flickr account at http://www.flickr.com/photos/dburkey/sets/72157632045204707/. The last one shows the naked GoPro just stuck to the quad with velcro. That's not how I intend on using it, I was just impatient and wanted to see a test.
I have a GoPro specific gimble on the way and I plan on putting the GoPro in the case if possible. Although I think the gimble is set up to use it without a case. :-)
Ahh I see I see... Given how you attached it, it was good to see no vibration. I tried to use velcro (with the case on) and there was quite a bit of vibration. I saw that people are using neoprene strips (not across the entire camera - just two little strips at either end) to reduce the vibration.
But that gimbal looks good... When do you expect it to arrive?
The gimbal should be here this week and I hope to test it this weekend. Stay tuned...
Ah excellent - staying tuned eagerly.
Sorry to break into the interesting discussion:-P I saw the GoPro2 camera and its mount (it seems ideal, although camera's a bit expensive).
How about the Quad itself? Is it from this store? In the end, I just want something that can be really stable to hover. Any suggestions/ pointer would go a step further helping me ;)
Yes, the GoPro isn't the cheapest camera out there, but there are 3 versions. v3 just came out. If v2 is a bit much, perhaps look for v1? Just called GoPro Hero and would also do a great job.
As for the quad, yes, I purchased mine from the store that you linked. I bought the quad version, revision C. In terms of hovering, yes, it would hover quite well and if you include the various flight modes it will stick to the spot without you having to do anything.
