So, here is a quick overview of what is probably the cheapest 2205 on the market today. At £6.38 for one motor, or £22.59 for all four, you will probably be thinking that this is another cheap Chinese underperforming motor for your quad. Particularly when one Brotherhobby or T-Motor motor can be as much as all 4!

What’s in the Box?

The motor turns up in a cardboard box and bubble wrap bag with a ni-lock nut, and 2 lengths of motor screws.

First Impressions

When this motor arrived, the quality surprised us. The motor metal was neatly machined, and the motor felt smooth to turn. The windings could be improved, they are not as uniform as in higher priced motors, however when you spend that little on a motor, you aren’t expecting the highest of build quality. Overall the build is surprisingly good. These motors are also exceptionally light, at 28 grams they are less than the emax RS2205 motors, which have the same stator size and kv. These motors can be purchased in the colours pink, purple, black, yellow, red, blue, and green, so they can match pretty much any colour scheme you want. The motor wires are thin silicone which make them very easy to solder, and the heatshrink is not too long.

Specs

  • RPM/V: 2300KV
  • Height: 31.5mm
  • Width: 27.9mm
  • Shaft diameter: M5
  • Motor mount hole size: M3
  • Weight: 28 grams
  • Voltage: 2-4S
  • Battery: 2-4S lipo battery

For such a cheap motor as well, we found these thrust specs to be extremely impressive. 950 grams may not be up there with motors like the new emax red bottom RS2205s motors, however these motors are less then half the price, and only draw 27.6 amps, meaning that they will not be as much of a battery buster as other more powerful motors.

Conclusion

These motors are great value motors that will make your quad fly. They are perfect for your first motors, due to their cheap price, their relatively high thrust numbers and ample build quality.  Of course they are cheap to replace, and will also take some time to grow out of as well. I would also say that if you want a  ‘basher’ quad these would fit the bill. They are so low in price that it would not matter if you broke one or two. We are going to release another review of our experiences with these motors on our new beginner quad that we are in the process of building, so keep an eye out for that article in the near future.

  1. You get what you pay for, I got $6 worth of thrust, a $9 motor (rcx 2206-2250) will smoke this motor and all parts are for sale (shaft $1, bell $4, bearings 21 cents), when I bought the racerstar, there was no spare parts for it, so you end up tossing the thing over a simple bent shaft. The 2250 is an older motor and is still pretty good bang for buck, the new rcx 2206-2400 V2 is $11 and much closer to the $20~29 motors.
