This frame was designed with the Runcam Split mini at the core of the process, as well as a top mounted battery.

The Main Plate is designed to accomadate two seperate 20X20 stacks, allowing for 15mm standoffs while still having space for the Split Mini stack and the FC/ESC. Its going to be a tight build, with 18-20mm clearance between the Main Plate and the Top Plate, depending on arm thickness; however that should be more than enough with the right stacks.

This is the Compressed X Version

This version uses the 50XX Arm Set on the front and rear, keeping the props as close together as possible front to rear.

3D Printed parts are neccesary for the build, specifically to mount the Camera.

As Armattan Productions doesn't do 3D parts, check out the whole set on Thingiverse. I've also design the following accesories for the cleanest possible build:

• R-XSR Tray - Mounts under the rear stack, could also fit a smaller RX 
• SMA Mount/Antenna Tube Mount - Slips over the rear standoffs to cleanly manage and SMA pigtail, RX antennas at 90 degrees, and a slot for the Battery lead.
• SMA Mount - no antenna tubes

I have also included some dimensions below, in case you would like to design your own camera mount or other 3d printed parts.

• Main Plate in 2mm or 3mm
• Top Plate in 1.5mm or 2mm
