Mini FSESC4.20 enclosure
An enclosure for a Mini FSESC4.20 brushless motor controller with mountings for bicycle down tube.

This tightly fits the flipsky Mini FSESC4.20.

121mm long 51mm wide, 23mm height above mounting tube.

There are M12 threads on either end for grommets of some sort, though I have just used hot glue as a temporary (5 years and counting) solution. 

Two down tube sizes available, 32mm tube and 36mm.

To install you need to disassemble the heatsink and remove the standoffs
The case is sandwiched between the heatsink and PCB.

Battery in one end, throttle and motor connection out the other.
