4/10/21: i scaled the throttle down at 80% to slow it down for my yard. now it feels like 1s 1202.5/1302.x 11250kv but with a bit more speed, power and weight. and it feels good.

it's similar to happymodel Crux3, but with a bit more power.

43gram,
frame: 2mm thick is ok, but if you do fast flips and rolls a lot, or crash a lot, then 3mm is better.
2s 27gram - 31gram batteries ( 450mah - 650mah )

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..

FPV has had quite a journey. Just a few years ago we started racing drones around a track and doing flips over trees, but professional cinematic FPV is a more recent development. DJI has always owned the drone photography market, but smaller acrobatic drones are starting to enter the market. They have the advantage of close proximity flight indoors and around people. There's more artistic freedom and..
