Racerstar Star20 4 in 1 ESC

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.

4 in 1 ESC separatedThis 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.

Eachine E010S 65mm Micro FPV Racing Quadcopter with 800TVL CMOS Based On F3 Brush Flight Controller

Micro FPV Racing Quadcopters, the new hype train that started as the winter was coming in the northern hemisphere.
After owning the Eachine E010, I have decided to jump on it and ordered this ARF kit.

55283029-3223-401b-8f00-f2a8c149f376

I have ordered this one from here, it is the Frsky version and this review will be regarding that one, I have no experience with the other versions except what I have read in other reviews and forum posts, mostly compatibility issues on Flysky (not compatible with FS-i6s R9B, R6B system and set your transmitter to AFHDS instead of AFHDS 2A)

Priced $54.99 as it is one of the cheapest micro fpv quadcopters, although you could spare few dollars if you look on Aliexpress for similar deals, but this seller seemed OK to me and I have decided that it is better to spend few bucks more than receive a broken or incomplete order.

The package includes:
1x Frame kit | 4x 615 59000 rpm ± 12% Coreless Motor | 8x Blades(2 Sets ) | 1x F3_EVO_Brush Flight Controller | 1x 800Tvl 40cH 25mW Camera | 1x 3.7V 45C 150MAH battery | 1x USB Charger | 1x Manual | 1x Blade removal tool

The build is good, similar to E010, the antenna seems a bit fragile so it is advisable to mod it in order to be protected in crashes. The flight controller is not F3_Evo but regular F3 which is worth nothing if you try to flash it with Betaflight or Cleanflight. This one was missing the dampening rubbers for the FC so I had to improvise and use silicon strip in order to minimize the vibrations from the motors and get top notch performance from the FC.

The Racerstar motors pack some serious punch for a build with this size and weight (26 grams with battery), unfortunately, such motors require a lot of juice and the battery lasts about 2 minutes so make sure you order plenty of batteries if you want to really enjoy flying. Fortunately, I have found that this micro quad could fly even with 500mAh battery instead of the 150mAh. The 500mAh battery tames it down so it is more suitable for beginners.

I have flashed it with Betaflight since I use it on all of the other miniquads that I own. It flies great, a bit sluggish compared to the brushless miniquads but this is a real indoor flyer, stable, precise and responsive. I can’t stop flying it trough my apartment if only I had few more batteries haha (never enough). The telemetry on FrSky works perfectly

Look no further if you are looking for a micro quad, this is the best one the money could buy.

Realacc Genius 215 4mm Frame w/ REVO F4 Racerstar BR2205 2600KV Motor RS30x4 Blheli_S ESC 5042 Prop

Realacc Genius 215 w/ REVO F4 Racerstar BR2205 2600KV Motor

Recently I have received the long awaited Realacc Genius 215 ARF package from BangGood.

Realacc Genius 215 4mm Frame w/ REVO F4 Racerstar BR2205 2600KV Motor RS30x4 Blheli_S ESC 5042 PropA really nice kit for a great price $116 at the moment of writing this post, it comes with 4mm true X frame which weighs 85 grams, Revo F4, RacerStar BR2205 2600KV Motors, 4-in-1 RacerStar RS30A ESC and RacerStar 5042 TriProp.

Before ordering this kit I have done some research to find some reviews of the components used.

The frame is almost exact clone of the QAV-SKITZO Dark Matter and it seems that these cloning companies have learned the recipe, every frame that debuts on GetFPV should be cloned 🙂

I have already ordered and reviewed Revo F4 FC and you may find a detailed review and wiring instructions here
This kit comes with 4-in-1 RS30A ESC V2 which is a proven ESC for simple clean builds on frames with super thin arms like X-Foot. These ESCs could easily handle most of the power hungry miniquad motors and in this case, they are more than enough, actually, I think that it may have been cheaper to use RS20A 4-in-1, but that is my opinion.

I have no real experience with the RacerStar 5042 TriProps, but I will surely gain some as soon as I complete and maiden this build.

There was already a great test video of the motors along with RS30A V2 ESC (not 4-in-1) thanks to Albert Kim

Conclusion: This is a great kit for the price, I would prefer a bit stronger motors and also it may have been cheaper if they have paired it with RS20A 4-in-1 ESC but all in all great package for the price, especially for the guys that are on tight budget.

I will post a flight video as soon as I maiden and configure it properly.
