Update: Quad lost to the mountains due to an unexplainable failsafe, possible crossfire antenna damaged.

Suffered a crash that lead to a full overhaul of my now retired 5" alien. First time building this frame I didn't know exactly what I wanted out of it. Decided that I will fly this quad exclusively for freestyle flying. Switching from betaflight to kiss setup and will be utilizing the new mr.steele/kiss pdb with osd for a clean and easy build. Using a 4" body because the 5" has so much wasted space inside the frame.

So far I'm very pleased with the flight characteristics of the 4.5 frame. Vary snappy and responsive yet predictable and easy to fly smooth. the 4" body is slightly lower and narrower than the 5" but leaves plenty of room to spare, and the fpv camera mount on the 4" body is superior to the 5" K-mount IMO.

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..
