Brushed frame for 66mm props (10mm motor holes)

Designed for FB90 Board and 66mm props (1mm between props)
I also uploaded solidwork files if you like to modify it for yourself
Calculations shows about 6.5gr as ABC
my expectation is about between 7 or 7.5 gr
it has 4.5mm thick arms and 0.5mm mounting plate (not really ;) thin i already tried 0.5mm many times)

FC will fit inside if you want or you can mount it on top with 2 sided tape and fpv will hang on front wall with double sided tape as my plan or you can tape it on fc everywehre i
