Great deal!

Arrives quickly, all specs working perfectly, just make sure you don't need built in vtx! Was exactly what I was looking for.

Awesome FC

Awesome FC for building small 1S whoops. Built in ELRS makes it easy - just hook up your VTX and camera and go for it. :)

Nice FC!

This is a nice lightweight FC. Got this one to replace the original which died because of an egg-cident (landed in a bowl of eggs my son was scrambling) and the board, and eggs, got fried. The original board was SUPER smooth so I wanted to go with the original FC to get that same feel. This is a really clean and smooth looking board. Very well designed for indoor technical flying. Probably well suited for flying in the trees too.
