I design this frame/drone to do hard flies in busy places like thick forests. I used 3mm thick plates for the main plate, so it can survive hard crashes. Pusher configuration with bottom mounted battery, which I prefer especially on smaller drones, feels smoother and more stable also the o3 unit is center mounted, so the CG is very close to the center. I use three different batteries, 550, 650, 850mAh 4s, the flight times around 3-6 minutes depending on how hard it pushed. It's a but heavy but I like the extra intertia, it reminds me to heavier drones, similar to tiny trainer.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. 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..
