Ciao,bellissimo il tricottero,vorrei costruirlo anche io,devo solo capire come cablare i motori il servo di coda alla fc f4 betaflight e come configurare il tutto.
Mi potete aiutare in questo progetto?

Here's my 3" version. Specs:

1)3D printed frame from PLA+
2)BE1102-7800KV motors with 3x2 props
3)BetaFPV F4 flight controller
4)BetaFlight 4.1.1 with custom config file and custom triflight 0.5
5)R-XSR receiver using Fport
6)350 mah 2s battery
7)I can't recall what the servo brand is, but it's a high voltage model
running directly off the 2s battery and modified for servo feedback

Only flown a few times so needs some more tuning work, but already it's
flying quite well.

Awesome! I love it! Are the design files available to print the frame?

I might print a regular quad frame first, but my goal is to build a small Tri.
