Rotorgeeks 30A BLHeli

Get a great deal on the remaining ESCs made prior to the addition of a programming lead - while they last!

The new Rotorgeeks 30A BLHeli ESC is available in a BEC-less version - the 5V BEC has been removed and the 3 wire lead is replaced with a single wire lead with a 1P housing, ready to plug into the signal pin on your flight controller.   Clean up your wiring,  No need to run 4 three-wire leads or cut and shrink the extra wires.  The pros have been cutting open their ESCs and desoldering the unnecessary leads.  In a quad configuration, one standard ESC provides common ground and power to the board while the three optos don't waste any energy or heat providing unnecessary 5v power.  The input capacitor has also been upgraded from 16 to 25V for ample headroom on 4S operation. 

Custom built for Rotorgeeks, this ESC is perfect for your 300mm+ quad build.  It's 4S capable and has a 5V, 2A BEC.  Yes, it'll warm up on 4S but the current requirements from flight control boards are quite low.  This ESC is flashed with BLHeli for the ultimate in configurability and compatibility with high speed flight controller outputs.  BLHeli also offers reversible direction (if you direct solder your motor wires this can save you a lot of trouble!)  For more info on BLHeli go here  ESCs are shipped ready to fly with BLHeli 11.2 Multi.  There is no need for further configuration.

ESCs measure 18mm wide x 9.6mm (12.6mm at input capacitor) x 54mm long (heat shrink edge to edge - board is 33mm+10mm capacitor=43mm)
- these ESCs are slightly smaller than the equivalent Rotorgeeks SimonK versions due to different components and board layout
25g with full length wires and heatsink

Mounting  The heat generating components of the ESC are located on the side with the label.  If you remove it, be sure to keep that side in maximum airflow..

What is BLHeli vs simonk? Both are custom firmware designed to optimize ESC performance, allowing the speed controller to respond faster to commands from the flight controller.  simonk works with Atmel based speed controllers whereas BLHeli works with Silabs based speed controllers.  BLHeli offers configuration capability after flashing  i.e. you can change the settings after flashing, even without a computer or USB interface (through stick commands).  The Silabs chips also have very good internal oscillators whereas the Atmel based ESCs require an external oscillator for optimal precision and temperature stability.  Some Atmel ESCs have it, some don't whereas all Silabs ESCs have this internally.

These ESCs have a beacon!  huh?  That's right, after sitting idle for 10 minutes (configurable) the ESCs will start the motors beeping.  While not ear piercing, the volume isn't too bad - this could actually help you find your quad in tall grass (or a tree!)
