I decided to make a fpv racer for 5" props with a lower cg. I looked at what features I likes best in the alien, chameleon, and Qav quads. After plotting out the motor spacing, I then worked my way up the frame. I will be working on other camera mounts, but is set up for runcam style cams.
The arms are setup for 2204 to 2206 motors and 5" props. I do plan to make some other arms for 4" and 6" props. This will see more changes once I get my motors and fc in. The main plate is set up for press nuts like https://www.mcmaster.com/#99437a135/=18wxmnj to be placed for mounting the arms. Stack height is limited but this is made to have the battery sit lower as to bring the cg closer to the prop line. This will be best with a flight controller with built in pdb and osd like the f4 omni aio boards.
Update.... The battery, base, and cross plates have a new V2 that is 3mm. Update 6/22/19 added the v2 camera mounting and a 19mm to 28mm cam adapter Update 6/23/19 Added rear pylon v2

*************** THIS IS STILL IN THE EARLY STAGES AND IN TESTING****************

print 2x rear pylon 4x 5in arms (set to 5mm thick for printed arms) 1x of all other parts.
