Not pleased with the strength of the one I was buying on Amazon so this was my replacement. So far i have not managed to break it, and it is lighter and less air resistence than the one I had been using Amazon. The frame came in at 3.6g, and the whole quad minus the battery weighs 30.2g. See http://fishpepper.de/ for build tips and components. 

My build uses:

2s tinyPepper 4 in 1 esc

TinyFish FC

standard 1s aio vtx cam for tiny whoop

racerstar 1103 10,000kv motors (old style without the screw holes in the top)  like: http://www.boldclash.com/boldclash-1103-m1103-1s-2s-micro-brushless-motor-p17.html

Motor Bolt pattern is 8.5mm 1.6mm holes with only 3 holes (i only use 2 screws)

5v linear reg pulled from old esc

3d printed camera mount. I have not actually posted my design, but you can used the fishpepper one.
