This is my first build ever. After owning a camera drone for a while, I'm curious about fpv. I buy a controller and a simulator and I've got  hooked. I get myself a Pavo20 and flying acro irl for the firstime and convinced myself to build one. So I think 3-3.5 inch frame is a logical start since I'm still a greenhorn. 

Boy oh boy, how wrong I'm. This frame is not friendly to a first ime builder. I had to flip the stack orientation, source a longer o3 air unit jst cable, and replace the stock speedybee capacitor for a shorter, solid 470u 35v upl cap to be able to fit everything inside this frame. For all it quirk, this frame fly beautifuly, even in 4s configuration. Of course I don't know how 6s fly since I've never flown one outside the sims. But coming from 2 inch cinewhoop, this thing rips. At last, I've build my own quad.
