HappyModel CrazyF405HD

I've just build this into a 2" HD freestyle quad and it's amazing! I love micros and this fits all the specs:

A) It has integrated ELRS to free up space.

B) HD port?! What more can you need for an small HD build?

C) Barometer??? This is starting to get a little crazy.

D) 3 UARTs... Perfect for an HD ELRS 2" micro build.

E) 1-2s... Great if you want to upgrade to 2s.

What more can you ask, this FC is amazing in all the ways possible. It's got great quality, design, and features. I would suggest this to anyone wanting wanting a really good flight controller.
