Thank you for purchasing your Fractal65! 

Your support means a lot to me and I’m humbled that you chose to trust my vision with this high-performance racing whoop frame.

This page will be the instruction manual on building and tuning your setup so that you may get the most performance out of it.

First of all, if you’re not the reading type, you may rewatch the assembly stream I made on my Facebook page. (Or at least follow me here where I’ll post any update on this setup)

Betaflight Configurator

I recommend using the Happymodel DiamondF4 AIO for this build; they are the lightest 1S boards that include an F4 FC, 5A ESC, 200mw VTX and Frsky (or Flysky) Rx on board.

The following Betaflight Diff comes from it, but any other AIO should work just as well, with a reserve on the ports and motor reassignment that may be different on other boards

Just copy and paste into your betaflight CLI tab

ESC Firmware

For the ESC firmware, I recommend BlueJay; a great development branch with cutting edge features including bidirectional Dshot, enabling RPM filtering

I recommend setting this up after dropping the DIFF in betaflight that will reassign the motors

You may chose between 48 or 96kHz PWM; the latter offering a smoother high end at the expense of lower thrust in the low end, but better efficiency overall; and vice versa for the former.

Motor direction should be good for your build too if you wire your motors straight to each phase in order

The only important setup is to change the timing to medium-high.

Increasing the beep & beacon strength is also recommended if you want to hear it better, and I lowered my timing to 2mins so that I can find it faster

3D Model Files (3MF and STEP)

The camera and battery holder are 3D printed, so I’m including the model files if you ever want to print spares or use the .step to make your own modifications to it!
