If you need help building it, or you need an adjustment made to the design, please reach out to me on my Discord-channel here:
This is a 4" Freestyle frame optimized for the O3. It's a mix between a DeadCat and classic layout. You still have a well protected camera, yet you don't have parts of your frame or much of the propellers in the image.
The weight of the frame parts is 76g (+8g for Bumpers, +4g for XT60 connector).
It uses bike-chain bolts to connect the arms to the main frame (credits to Dave_C who first came up with this idea). The advantage is a strong connection yet very light, and it only uses 2 screws per arm that are easily reachable without any disassembly - so you can switch an arm very easily and quickly on the field.
In my build i cut the arms out of 4mm carbon, the rest out of 1,5mm white glass fibre plates... just for the looks ;-)
Hardware needed apart from the CNC cut parts:
- 6 x bike chain bolts (with a height of 5mm - important!)
- 6 x 20mm M2 spacer bolts
- 12 x 4-6mm M2 screws
