DC130 Session build

Our main goal when creating Atto was to make micro frames that performed every bit as well as their larger competitors. This monster build pushes the boundaries of 3″ performance and still carries an HD camera with the integrated session mount.

To see just how much power we could get we used RCX H1707 motors that push over 500g each on 4S and kept everything as neat and light as we could.

The micro top plate offers plenty of room for the VTX with a direct soldered antenna. To keep the mass as central as possible and add room for the props to clear the back of the FC we added 3mm motor spacers and 8mm M2 bolts.

40mm standoffs offer plenty of room for the 4in1 ESC and FC. Sandwiched between the two is a micro 12V BEC that feeds the VTX power. The VTX offers both 12V and 5V out to power the Foxeer Arrow camera and flight controller making this a super clean build and easily our favourite so far.
