350 'Hammerhead' homebuilt quad.
Here it is! The long awaited 'H' frame I've always promised myself....

Well, it occured to me a few days ago, that I have most types of multirotor frame in the air (save a tri of course) but have so far neglected the 'useful' H. To address this issue, I thought I would attempt another homebuild, using my slightly improving CAD design skills, and my trusty Delrin.
Here's a jpeg of the v2.1 (yes 2.1 already!)
Version 1.0...
Resplendant in cardboard, the basic first mockup, which I rather liked, but above is where it's at at the moment.
V 2.1....!
V 2.2!
So this is the last mockup frame I made from card, and was pretty much good to go. Just a few mods to lightening holes, and removing the extra mounting holes for a Mobius style camera, and replacing it with custom hole for HK lost model alarm buzzer...
And here she is (actually v 2.3 to be pedantic)! Just like a good old kit. It all fits together beautifully, but of course, as soon as you cut one of these from the real thing, you notice things you'd change, like the bolt holes on the cam plate should be 2mm, not 3mm! Also, the motor bolt holes will probably not be 3mm, so I'll have to wait until my Airbot 'Micro Titan' 2204's arrive from the States before I know for sure.
I have elected to use aluminium standoffs, although I will still utilise the plastic 10mm spacers to separate the bottom and top frames, the 10mm carbon box arms will provide extra rigidity to the frame.

Well, my Airbot Micro Titan motors have turned up from the States, and look very nice.
However, it's clear to me now, that the motor mounts need a tad of radicalisation, in the form of the above. I didn't like the idea of the bolts through the carbon arms, so decided to try the clamped method.
Here it is on the left..
Cable ties may be an option here.
There may even be an option to adda little vibration dampening while I'm at it.
Bolted together with 3mm bolts, I'm quite pleased with how well it grips the arm, without having to torque them down too tightly.
I may add rotation arrows or motor orientaion info, as all these FC's seem to have different motor layouts and rotations, no standardisation!
