# Flash SkyRC Swift 10A with BLHeli firmware

## Hardware

* Arduino MEGA (better), or  Cheap USBAsp from eBay
* Soldering iron
* Enameled Copper wire, diam 0.2mm
* Solder
* 3 Pin female header pitch 2.54mm
* Large heatshrink tube. I used diam 24mm.

## Steps

### Hardware 1

* Remove the plastic of the ESC
* Glue the header onto the regulator (next to the cap). Try to have it flush the edge so you can keep it accessible for later.
* Solder the wires from the test points to the header
* Connect the header to the arduino mega
* Power the ESC

### Software

It's a little bit complicated for two reasons: I first used owSilProg before I discovered BlHeliSuite and I couldn't flash a new ESC directly with BlHeliSuite. But it worked, on ten ESC.

* Get owsilprog
* Use the AVRBurn tool to flash the firmware onto the arduino mega
* Use owSilProg to flash the ESC with BlHeli. Select HK10A MULTI.
* Flash all your ESC
* Get BlHeliSuite
* Use the AVRBurn tool to flash the BLHeliSuite programmer firmware (use the PB2PB3 or MULTI one (I think))
* Reflash the ESC with the most recent BlHeli firmware

### Hardware 2

* Cut a length of heatshrink tube so the ESC fits in.  Have 3mm on both sides of the board.
* Heat in place
* Fly the damn uav !
