Colourful Ring Series

The Emax Colourful Ring motors are very powerful motors designed for very small aircraft that are around 7oz or less. As you can see from the photo, the name sure does fit the appearance. These little guys do have a pretty amazing punch for such a small size motor!

There is really only one size Emax Colourful Ring motor that are wound to two different Kv ratings. The CF2822 is a 1200Kv motor and the CF2212 is a 1500Kv motor.

Great for Protech Skyraider and easystarlook-alikes.

Long flighttime saves lipo. But now i'mlooking for a stronger motor. look for near vertical climbing power.

New to model electric motors and put this in a glider. It had been running ok but on occasions it would not start or growled then ran up to speed and then cut off.

Had changed the ESC on assumption faulty but did not remedy.

On changing ESC again I noted that the motor windings are not terminated in the motor but are brought right out to where you solder on, and then covered with heat shrink. Of the 6 winding wires at each terminal I note that a couple were broken which would result in the problems I had been experiencing.

Have re-soldered which included scraping varnish off to make a good joint. All appears ok now.

I was impressed with the motor as it fairly pulled the Laishing Thunderbird about with no problems. Hopefully good weather tomorrow and will see what happens.
