Im going to try something a bit interesting. iFlight has a new AIO 40A ESC with a F4 FC built in. One board, 30x30 mount.
I am going to 3d print an adapter and install the DJI Caddx Vista VTX on top the AIO board, under a 3D printed pod for the FIVE33 Switchback frame.

If my math is right, I will be at around 225-240g without lipo. Pretty damn good for a DJI racer.

For now I run 5s, but may swap motors or do motor scaling and go to 6s eventually.

As soon as the vista shows, ill build this and get some photos and videos up here!
