Whoopee micro ducted brushed build: low profile tiny whoop with 8,5x20mm brushed motors - BUILD LOG

Winter is coming soon and ducted micros are entering my to-do list once again.
I have wanted to do a 8,5x20mm whoop style micro quad since I first saw this frame design on Oscar Liang's blog.
It is a well thought-out frame, it can fit most brushed boards and can be easily converted into a low profile ducted beast. It is a bit fragile though, which is probably its main downside.
Placing the battery on top balances the weight nicely and it performs much better than a tiny whoop, allowing for fast recoveries and fun acro practice indoors.
The 750mah nanotech shown in the video is the biggest battery I would put on this build and only for cruising - smaller batteries of course improve the feel drastically.
(no DVR footage, sorry - I crashed it very hard and broke off one of the motor mounts)
This is BUILD LOG: Whoopee build (low profile "tiny" whoop with 8,5x20mm brushed motors) - Let's go!
