Tiny Cine Whoop

Had an old small 90 mm drone that needed a new life.
Made some ducts and tried it out. The version with the largest ducts did only barely fly with a small battery,
I cut about 4 grams on the frame and now it flies with the 550mah battery just fine.

It uses the 8,5 mm motors. Motor fit is not that tight.

Needs some motor protection on the bottom.
The weight comes in as the QX90 withe the square frame.
