Building an H-Quad

Here is a H-Quad that I just finished for aerial photography. For testing purpose's I installed a free flight controller to check stability. Now that stability checks out, I will install a Naza controller. I have recently purchased the new Sony HDR-AS-10 action cam and it works flawlessly on this frame. There is no rolling shutter, jello effect or vibration at all.
Here are some photo's of completed frame, also the sony cam mounting.
Indoor first flight test can be seen on my youtube channel.

H-Quad Ver. 2 with Aluminum Arms (1 min 26 sec)

Love these H frames. Easier to build than quads I am thinking.
Quick question. Why did you put a motor mount on the arms? I thought the arms were strong enough or..?

I'm using 10 4.5 props, they give plenty of lift.

I used the motor mounts because I think it gives the motor a flatter area to bolt up to. The tubes being hollow I also cut short pieces of hardwood and press fit them between the 2 mounting bolts so the tube would not crush when tightened.

Overall a pretty nice work - thanks for sharing here.

I'm not entirely sure, but are you, kind of, enclosing the ESCs in packing foam, to stop them from rattling around ?
If so, I would maybe worry a bit about cooling - are they warm after tests/flights?

No the ESC's are located on each end which is open to air flow, the foam starts past the front esc and stops just before the back one. The esc's are held in place with double sided tape, no problem with over heating.

Nice Hquad

I would still be concerned about overheating, even with the sides of the frame open. I like mine to be in the propwash on the top or side of the arms. Our escs were designed with air cooling in mind. Just keep an eye on them.

Looks like a real clean quad! Im building my third quad in a few minutes.
