Racerstar 2205 BR2205 2300/2600KV Racing Edition Motor [$8]


New BR2205S motor design are available for purchase.
Racerstar had tweaked a few things and it looks much more professional while the price almost the same ($8)

Primary improvements
  • Upgrade propeller base
  • Anti-skidding screw thread to prevent propellers from skidding.
  • 5mm stainless hollow shaft

New Motor Design

General Tip
The RED nut means the motor has CW thread (Motor spin direction => CCW)
So choose CW to get the standard thread type.
Myself, I prefer purchasing 4 Standard motors (The nylock nut is strong enough to keep the prop in place)


If you prefer 2CW & 2 CCW motors, you can save $2 if you buy 4 motors:

Higher Thrust Motors edition the "RF"
* These motors will generate higher thrust and more powerful.
Its recommended to use a good quality High C rate batteries with these motors.

I received my 2205 2300KV Motors along with the Racestar 20A ESC'S.
The motors looks really good and has good quality, they run smooth by hand






My Low-Cost FPV Trainer

I really made sure every part will be low-cost.
lol



FRAME: qav210 - ebay clone
FC: Naze32 (taken from the past - year 2014)
FPV Camera: HS1177 Clone ($24)
ESC's: old little bee 20A not pro



These motors surprise me with their level of quality for a $8 motor.
They are smooth and only 1 out of 10 did make some noise when spinning it by hand.



The power and flight performance feel like the EMAX 2205 2300KV but just a
little less power than the Emax.

Over all this is a great motor to build a budget racer for under $200,
I use it to train my friends and improve their skills with 2 TARANIS RC and a trainer cable.

2gr lighter than the kingkong 2205's. Can't wait to see some reviews or an EngineerX thrust measurement. These cheap motors are becoming so good in terms of thrust. (allthough, it might be a slightly higher KV than spec'd)

The maximum power should be gr, not W. (error on the banggood site)

I think the "dry" numbers doesn't tell the full story.
Dynamic testing and performance teach you a lot more than static thrust tests.

I believe the performance of the motor on throttle range between 40 - 70 % are much more important, because most of the time we are at that range while flying.

I've ordered 5 motors and will test them soon in flight.

Wait, those are budget motors? i think BG sent me the wrong ones, the ones i received feels like 3 times their price... They are gorgeous, their bearings are ultra smooth, there is zero vertical play and there is some trace of blue epoxy on the magnet, meaning that they have been balanced... I cant wait to install and try them fo see if they perform as well as they look.

You sold me, going to pick up a few as emergency replacements, and before prices go up

I wired one of the motor with the racer star blheli_s 20A esc for testing. Very impressed on how smooth the pair run. The bells were indeed balanced at the factory. With a GF5045BN on it, it seems to output quite a respectable amount of thrust, more than the RCX 2205 or Cobra 2205 I concur. But that's just based on feelings, I'll leave the scientific tests to the like of QuadMcFly or EngineerX
Another thing is that it seems that the motor has some kind of active cooling, when I ran the motor bare, there's some air flowing from the bottom of the motor.
And the icing on the cake would be that the lock nut provided is made of aluminium alloy... (The Emax RS2205 came with a steel locknut...) Some shop would sell the same locknut 5$ lol...

As Danq0 said, the price will probably go up or/and the quality will suffer to meet the demand, so it's probably a good idea to stock as much of those little gems as you can

i can atest that the quality of the motors is in deed good, especially considering the price, what amazes me is the amp draw on them, i was flying on dal 5x4.5x3 v2 props and it was only pulling a total of 60 amps, at the same time being really fast,
that blew me away since dys 2205 2300kv will pull well over 100 amps and the emax red bottoms will pull 80amps, although the red bottoms seem to pull faster on the same exact set up, the better effieincy is always welcome, since its more flight time

Think these are better than the kingkong2205? I need to decide on one or the other...

According to people impressions so far they might be better, still not enough info.
I'll be getting my motors in a week or so, and I'll upload a nice overview and tell what I think.

I did a thrust test on my low tech bench setup with a gemfan 5045BN and a 4S lipo, and it errored out my scale which has an upper limit of 1000g. So thrust wise it should be close to the king Kong
I don't think you can get wrong with any of them, they are both amazing value. However I do prefer the racer star look, their lower weight and the alloy locknut that comes with them.

Would you perhaps have measured the amperage? I still need to buy some ESCs to go with these motors and I don't know weither I should opt for 20A or 30A. I am going to use 3S lipo's, would 20A be sufficient then?

it depends on the props you want to use them with. 20A is enough for any 5" prop and 3S. A 6045 is borderline but should still be OK.

I fly super aggressive and I know more than 20 Pilots that fly in the same style, we never used 30A.
In my opinion it should be used only in extreme cases such as 6 Inch props Triple blade with more than 4.5 pitch.
