This is my first bulid, never had a 4" before so when ImpulseRC released the micro apex it was love at first sight.
Went for the 4" and not the 3" since a 250g limit is not a constraint in my country due to the fact that FPV is illegal here:)) I did not take enough pictures mid-build, sorry for that, was too busy trying to figure out how everything sits together in harmony, turns out that this is most of the challenge :) The dry weight is 223 grams.
Take notice that the this 4 in 1 ESC is a bit big for the build and sits really close to the vista (I had to remove the capacitor and lengthen its' legs), that could be solved by mounting the ESC facing the rear and not the front and reconfiguring motors order\arrangement\alignment in betaflight.

Mar 04, 2021

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
