I wanted a light weight, 'free range' quad capable of swinging a 6" prop, as well as, handling 6S packs (although not at the same time).
I started with a 6" Hyperlite Floss 2 for the frame - it's light, cheap and plenty of space inside. Plus I'm not gonna be racing this thing - so spindly arms are a plus. Second, I wanted a proven low kv motor - if the Brotherhobby T2 2206 1800kv were good enough for DRL, then they'll work on this thing. Although, they are a bit porky (33g)... Match those motors with a Wraith32 4-in-1 ESC (capable of handing 6S) and an Omnibus F4 Pro - I've used this stack with success in the past. To shave a few grams (and a save a little $$) - I used a Caddx Turbo Micro F1 coupled with an AKK FX3 VTX. Finish it off with a Crossfire Micro RX and it's good to go! Added a mini GPS!! Super easy to do and the 18x18mm micro GPS is crazy small and light weight. I modified my hood to top mount the GPS.

I wasn't really happy with the traditional top plate so I designed a TPU hood for the Floss 2 which crams all the above under the hood using 15mm standoffs - it's tight, but it works. Everything but battery came in at 262g... not bad considering the motors. I've got a set of old Cobra 2204 1960kv sitting around which would shave about 30g in weight... might be worth a try.
