Comments:
This looks like it is going to be a great setup. However, there were some things that I had to modify to install this on a 210 sized mini quad.
The stack height of the package is quite high. The mini quad frame was made for a 2 board package with the camera mount quite low. I've had to reduce the standoffs between the frame and ESC and ESC and Flight Controller board by 2mm each, giving a height reduction of 4mm overall. Additionally, I had to grind 5mm vertically from the frame. The total is 9mm more vertical clearance with 1-2mm to spare.
Pay no attention to the motor markings on the 4-in-one ESC. The numbers do not correspond with the motor layout of Cleanflight. After puzzling about this for a while, I traced the pre-soldered micro plug wires and found that they are correctly soldered to correspond to the correct physical motor layout.
The power lead location on the ESC faces forward on the frame which is not ideal for me since I prefer my battery leads and voltage monitor to be on the rear of the craft. Rotating the board 180 degrees will place the female micro connector beyond the reach of the pre-soldered PWM wires/male micro plug. I plan to install the ESC in the standard position and extend the battery cables to the rear of the craft.
For ultra compact X frames 210mm and smaller, you will run into FPV camera clearance when running the standard square housing HS1177 type camera. The SD card impinges on the forward clearance for lowering the FPV camera angle. On my frame, removing the SD card provides enough clearance to almost match the lowest angle of the Go Pro mount. I plan to modify the frame by drilling new camera mount holes diagonally 4mm up and forward.
