Star20 is the newest 4 in 1 ESC from Racerstar that for the first time offers a unique feature, each ESC is detachable.

I saw this item posted on BangGood and it seemed like a nice logical step forward in the 4 in 1 ESC development so I have decided to take a look and share my thoughts.

This is the long awaited feature for all fpv miniquad racers that are flying 4 in 1 ESC combos on their rigs either they want to have a clean build or they have some of the newer airflow optimized frames with thin arms.

I have seen several burned 4 in 1 ESCs and most of the times nobody cares to repair them so you have to throw it in the garbage even if only one FET is burned. They are a bit cheaper than buying 4 regular ESCs but it seems a waste of money throwing three working ESCs when only one is burned.

This item is on preorder at the moment and looking at the photos, I’m not sure if the ESCs come soldered or separated (they probably packed with shrink tube). Either way, if they are separated it will be required to put a few blobs of solder in order to connect them and there is no delicate soldering required.

I think that this is the first 4 in 1 ESC of its kind and probably more will follow.

At this moment it is few bucks cheaper ($29.99+$0.34)than regular 4 in 1 20A ESC listed on BangGood from the same company.

I’m considering buying one of these since I’m planning a new build based on the X-Foot frame, but maybe I will have to wait for Racerstar to release Star30 30A 4 in 1 ESC in order to use it with some of the new powerhouse motors that are available on the market lately.

Update: It seems that FPV Model is already offering similar product X-Racer Quadrant 25A and it is in stock at the moment. The only downside is that this one is a bit longer so it may partially protrude out of the frame.
