Review of Racerstar Star20 20A Blheli_S 2-4S Detachable 4 In 1 ESC




Racerstar Star20 20A Blheli_S 2-4S Detachable 4 In 1 ESC D-shot Ready for FPV Racing Drone

After package delay about 40 days I finally received the brand new Racerstar Star20 20A Blheli_S 2-4S
Detachable 4 In 1 ESC from Banggood.com

First impressions:

The ESC are nicely packaged into electrostatic bag and they include big plastic standoffs and instruction / user guide.
Nice thing about this model of ESC from Racestar is that they can be dismantled in 4 ESC and easily returned to the
one piece again. Also you can order single one in case of damage or failure and easily solder and group it 4in1 ESC.
Quality of solder joints is done well and all components are on place , and they come with silicon wires that are
already solder on board .







INSTALLATION
Installation of Star20 is very easy you need to solder motors and VBAT and put signal wires on your flight controller.
Only thing is that can be done better is plastic shrink. It covers screw holes and you have to make a cut on shrink or
take little pressure for inserting a screw / standoffs.


Racerstar Star20 4in1 ESC weights only 16g ( individual weight of ESC is 4g )....






Dimensions 4in1 ESC:






Dimensions single ESC:






How to dismantled in 4 ESC and easily return to the one piece again
The board was difficult to break apart , be careful because you can ruin the ESC.. I suggest not to dismantled it






I used glue to consolidate the PDB and to solder it easily

Nice review. I see you took extra effort to disassemble and than assemble the Star20 ESCs. Great work.
