3" Red Black concept 2.0

I really liked how my previous 3" build turned out "red black concept" , but it had few problems in its frame.

In this build I wanted to fix those problems and I designed my own 3" frame to:

have Wider body so I can top-mount my battery without fear of props hitting the battery.
have two 20x20 mounts so I can mount my stack side-by-side and make this build super slim :)
Enable super slim build ;)

Final build is using 10mm standoffs and battery can be top mounted. Final weight (without battery) is 98g so it flies really nice :+1: .

I just made a hardware transfer from that previous build into this new frame.

Love the ultra slam. I've been thinking more that double 20x20 mounting is great. Do you have props in view? Looks like the ams are wide enough to be out of the way.

Maybe I'll use the same frame with cookie-brown color on white standoffs to create that icecream sandwich look :)
