Paul, as long as you got two legs, who needs arms. Don't worry about the arms...

Yes, previously Tim did say, he will sell parts too. That's another good reason to buy local.

Edited: I am thinking around $19-$22. A single DJI arm is around $11. What do you think?

I guess that depends on how easily they bend/break If I have a little less than graceful landing... which never happens ...and they bend, then $19 is expensive. If they survive all but the most serious of crashes then $19 is fine for such cool looking arms

Valid point!

I think just like car manufactures, Multicopter vendors need to show a "Crash test" result

But, I think it would be very helpful if Tim makes a video of the product, showing it in detail with close up shots and explains the product, it would be a great educational material. He can show close up the look and feel of the arms and drop the frames on hard ground (no electronics please) just to show how it survives a crash.

I thought about a video that goes over the frame... but had not considered dropping the frame before....

The arms by themselves are very very stiff. I tried bending and flexing them with my hands, but I can't -- but that does not mean they won't bend in a crash. It obviously always depends on the crash. I had crashes with one of my tricopters that seemed really bad, yet none of my wood arms broke. Then I had some that seemed minor, yet an arm broke.

My goal for the QAV500 was to make the frame perform as close as possible to a big hexa with a gimbal but at a fraction of the cost. I think the video I was able to shoot and post earlier today gets me where I wanted to be.

Haven't you seen that video from DJI where the guy throws the frame around, jumps on it and so on. But not that crazy!

Yeah, and those frame arms snap faster than I can say "oops" when they're actually loaded with motors / batteries in center.

Anyone can jump on a blank frame and yeah, nothing will happen.

I agree TC. I was just using the DJI video as a joke and not a real testimonial. Just kidding with Tim.

Isn't that QuadAddict? Woah, looks like he just finished his own frame with a strikingly similar design? Interesting!

No disrespect to anyone here, but I have known QA for along time and he has been making the aluminum arms for as long as I can remember. Also that new frame has been in the works for awhile. Yea they both look about the same. But honestly who really cares personally I think the more people out there making frames the better. Gives more options. I think both frames look great. And I hope this won't get into a who copied who war. People will buy from who they want to. And I say you can't go wrong with either frame.

For all intents and purpose, it makes absolutely no difference where your flight controller is mounted on the frame. Provided that your FC is oriented appropriately, mounted flat and is properly indexed with the aircraft's azimuth, it will compensate exactly the same regardless of its location.

You can mount your flight controller on a stick stood off 10 feet to the side of your quad and it will fly fine as long as the stick is rigid and the FC is mounted with the above criteria.

Other than that, I really like the frame. Camera mount being isolated ought to work great. I'd actually suggest mounting the FC on the non isolated portion of the frame. In most cases, adding a mechanical means of vibration filtering to an IMU will actually increase it's control deadband as well as the likelihood for the system to drift. As long as your props are balanced, stock tape mounted directly to the airframe usually works best.
