I like the Tarot 680 Y6 conversion that I currently have but it is still a little bigger than what I want. Plus it is bit an over kill to lift a gimbal with a gopro camera. I did some searching on the web to see what other options I have and the HJ-H4 Reptile Quadcopter came up.
In addition to the frame he included 2 distribution boards and one of them even has a built in BEC.

As you can see in the picture, with the arms folded in the frame is pretty small.

With the arms extended I can fit 13" props but I might be fit even larger props if I wanted to.
I also like how it has rail system on the bottom of the frame for me to mount the landing gear and gimbal.

The view from the top show some of the interesting cutouts, because it looks kind of like a transformer logo.
