Review: Cobra Champion 2205 2300kv Motor

We have tested the new Cobra Champion 2205 2300kv motors. This review is purely based on flying experience and impression about these motors, thrust data was not measured.

Cobra motors are sent in by Innov8tive Designs for testing, motors are tested and reviewed by Artur Banach.

New design from Cobra

The old Cobra 2204 mini quad motors were a huge success in the mini quad territory for a long time. Their design remained unchanged until these new Champion series.

Motor weights 29g each including wires. Each motor comes with:

  • A set of M3 motor mount screws (6mm long)
  • 1 x M5 prop locknut (integrated washer design)
  • 1 x M5 normal locknut and 1 x M5 washer (same as with the previous motors)

Compared to previously all black Cobras, the Champions have silver bottoms and black motor bells. The redesigned bell has more cooling fins and optimised airflow. There is no more Cobra logo engraved on the side of the bell, just the “Cobra Motors” text label. Motor shaft is held in place by a C clip like the previous version.

Build quality is excellent and bearings are very smooth.

Flying experience

I have flown Champions motors on the following setup:

  • Frame: QAV-X
  • ESC: DYS XS30A Blheli_S
  • Flight Controller: Air32
  • Battery: 4S 1300
  • Props: HQ S5x4.6×3 Durables
  • FPV: Sony HS1177 + Aomway 200mw
  • HD Camera: GoPro 4 Black

I took the quad to an open field with some gates setup. Flight video here:

I compared the new Champions to old Cobra 2204 2300KV I flew for a long time on all my 5″ racers. As soon as I pushed throttle up on the Champions I could notice the difference.

First of all, throttle response was much better. The quad was accelerating much more faster, it was just very obvious. I used new HQ durable 5″ triblades with them and motors were very smooth throughout the flight. They were also very punchy, I have had no problem getting through gates with quick change of direction and sudden turns.

The Champion motors can pull 1.2+Kg on HQ 5x4x3 props which is really impressive. They seem to be a good choice for racing, and the 2300kv is a good balance between battery life and performance.

Overall Impression

Positive:

  • Solid material and build quality
  • Better cooling
  • Powerful with good acceleration
  • Reasonable price (compared to other motors in the same catogory)
  • Two sets of prop locking nuts included

Negative:

  • Weight, still bit on a heavy side
  • After few crashes one motors developed the vertical play on the motor bell that previous Cobras also had
