Need Copter v.3.5.2 firmware

Anyone have a link to the v3.5.2 firmware, or have the .hex file?


Just download through MP firmware installation page.
Selecting “All Options”


Go a bit further. No copter.

why do you need such an old firmware?

Try Install Legacy Firmware. In the lower right corner there is a drop down box to pick the firmware version. AC3.5.2 was on the list.
