I loved my ultralight R4 1806 build. I never got mine quite as light as yours (182g) but I wasn't using 20x20 electronics. I loved it until the bearings on the motors fell apart and it became a nightmare to fly fast because there was so much noise.

It seems that 1806 motors are quite fragile.... did you swap the bearings? with new one...still noisy?? Mine is very noisy too. I should swap bearings! thx for the idea!!! ;-)

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..
