This is my attempt to build a ultralight 1s 85mm whoop. I should have go with a diamondf4 elrs, and save another 2 grams, but worked with i had at the moment. So i've stripped off the board connectors and soldered the motors on the board (to remove board connectors and motor plugs saved a gram).
Tested with gemfan 2023 and hqprop 51mmx2. The first one provided more punch, at expense of add about 2.5 grams and is less efficient. The later provided 5:30 of flight time with a 450mah 1s, which is not so bad. It's raining too much now, then i'll fly outside later.

It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

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..
