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.
