In my last post about HC-12 RF modules I showed my DIY telemetry rig for UAVs and quite promising result of 450m in open space. Today I post edited video of that flight. Most of the time it is Acro mode. PosHold and RTH are engaged in second half video material. Weather was rather windy with strong gusts, specially on altitude above 15 meters.
