r3dshifters new whoop frame goes ultralight!
it's a sprightly 3.3g with all the bits! (this includes canopy)
the build is standard whoop easy. mostly plug and play. surprisingly my betafpv v2 1s board came with O_H esc firmware so I was able to install jesc patch and run rpm filters on betaflight 4.1

the tolerance of the hoops on the frame is tight which is good but sometimes the props (at least these ones) will rub but a few squeezes on the hoop will recenter them.
I need a more accurate scale but this tips it right at 20g. I think I could shed a gram with direct solder and 3 or 2 blade props...maybe a rainy bored weekend. as it is though, this thing rips. extremely locked. The camera mount is awesome with a fully adjustable tilt...it just vibrates a bit when you throttle up. nothing a dab a hot glue wont solve, either that or I've found I can push the battery right up to the camera and it keeps it from vibrating.

vids forthcoming!
