Best for tinywhoop

"Lightweight, and a solid 5in1."

— Alexis L. (5/5)

One of the lightest

"Great FC for the smallest whoop builds"

— Q S. (5/5)

Super fun for a tiny whoop build.

"I use this for the fractal 65 and I’ve only had it for two days. I hit a Rubik‘s cube and few other freestyle tricks my second day in the frame is strong as heck I love this set up."

— James D. (5/5)

Amazingly lite!

"If you want ultralite aio this is the board for you. Fits perfect for my Fractal75!"

— Charles N. (5/5)

Great board for ultralight whoops

"Got the BMI270 gyro and couldn't be more satisfied with the Diamond f4."

— Gilbert R. (5/5)

Awesome ultralight FC

"Amazing ultralight fc for 1s whoop build or a replacement for Mobeetle6 or similar. Can run 1002 19,000kv very well for 50% more power!"

— Gavin G. (5/5)

A great little AIO

"I bought this HM diamond f4 with ELRS and it works perfectly. I have many, many flight on it. Betaflight 4.4 flashed perfectly, updated my passphrase and bound to my Zorro transmitter on Version 3,x. I have heard a bunch of chatter about this board, but my experience is great andxI ordered a second on for another whoop."

— Chris C. (5/5)
