X 4inch Tube

Dismantled the defect XXS Lightweight FPV Quads and Afro 170 / Afro 170pro to harvest some parts.

Wanted to have a small simple frame with a simple exchangeable fpv canopy this time - AUW under 250g. This version is the 4„ Frame made out of one carbon fiber Tricopter arm from RCExplorer. There is although its smaller sister, the X 3inch Flat.

The Prototype was flying pretty good, but ended up somewhere far - i guess in a tree. RSSI Search did not really help this time and had to watch the voltage go down on the telemetry screen until the signal was lost.

After that was was lost in the forest, i started building a new one with the better Brotherhobby motors and a small 20×20 AIO Board.

Many many Flights and many many Crashed later this thing was still my favorite quad, indestructible and powerful - until it took a small bath in the pond Well, time for an upgraded AIO FC and some digital FPV.
