Just a quick post: I just finished testing a Gemini adapter for TauLabs flight controllers which makes it super easy to use any FC instead of the Colibri, with minimum wiring...
Below is an example with the BrainFPV FC. Took about 15 minutes to wire it up, and it sits nicely on the Gemini. The top canopy does not play nice with it, but you can't have everything
One really nice aspect, is that is it fully self-contained: you can just swap the flight controllers without having to connect/disconnect extra wires.
I can probably make a couple more if anyone's interested, just contact me direct!
