Excellent on 3s for props of 7" or less Review by Dr Phil All my reviews  (1)
Overall Rating
SunnySky/EP Buddy X2204-21 (~1875Kv). This motor, when fitted with 1.8mm Hyperion Gold connectors, weighed in at 22g. It is 27.0mm diameter and 18.8mm front-to-back. It is a 12-arm stator, 14-magnet pole motor and the magnet ring is 5mm deep. I’m told that the stator plates in this series are 0.35mm, but that a newer series is due out soon, and will have 0.20mm thick stator plates… it will be very interesting to see what effect thinner plates have on performance. The 3mm shaft is, overall, 23.3mm long, with just 3.5mm exposed ahead of the built-in prop-saver. This prop-saver has a hub for 5.5mm prop hub bore (and the two additional hub spacers which are supplied, suit 7mm and 8mm prop hub bore). The two prop-saver screws are 2.5mm x 7mm flat-head at 120 degrees to each other. The four-armed built-in back-plate mount has 2.1mm holes at 31.5mm centers. Four 1.8mm mount screws and four O-rings are supplied with the motor. The machining and finish on this motor are excellent.

I set up this motor on my ply-disc mount on the test stand (see photo). I used my usual Zurich power supply, Medusa Analyzer Plus, Eagle Tree v4 with RPM and temperature probes, and Ohaus CS2000 digital scale. I used my “no-name” IR Gun, a Hobbico Digital MiniTach, and a Castle Creations TB 9A ESC.

I ran no-loads at 7v, 8v, 10v, and then a series of props at 7v-11v on the PS ranging from 4.5x3 GWS HD up to 7x3.5 GWS HD. I also tried 7x4 APC SF and 8x4 GWS HD on 7v and 7.4v to simulate 2s operation. The motor ran absolutely smoothly with all these props. Drive Calc estimated Kv as ~1875Kv (fractionally higher than the spec. of 1800Kv) with an Rm of 0.40 ohms. The critical “RPM as % of Kv x V” indicated that most of the props, even up to 7x3.5 GWS HD, did not unduly load the motor, but that the two largest props (7x4 APC SF and 8x4 GWS HD) were both bogging the motor down (65% and 61% respectively). With the 8x4 GWS HD especially, this low “RPM as % of Kv x V“ [hence…over-loading] was reflected in the rapid rise in temperature… a few seconds at WOT was enough to get the temperature up to 52C. For indoor flying where light weight and high thrust is of the utmost importance, one might get away with brief bursts of WOT with these larger props on 2s…. but for more continuous use, smaller props will work better!

Cheers, Phil

Comment to the post about the prop adapter falling out Review by Casey All my reviews  (2)
Overall Rating
I have two of these motors now and they are great. If you are worried about your prop adapter falling off because you hit the floor with your prop which alot of us do. What I did to fix this issue was, put some red lock tight on the prop adapter ring and stick it to motor and then put the prop on and let it sit. I have had no more problems with loosing my adapter rings after doing this. (Posted on February 5, 2014)

Best 32"-34" EPP Foamie Power Review by DanBo All my reviews  (6)
Overall Rating
I've built quite a few EPP foamies and have tried many motors. The SunnySky X2204-21 KV1800 has proven to be the best. Power, efficiency, light weight reliable top quality at a great Buddy RC price. The motors spin 8x4 or 8x4.3 props on 6a or 7a ESC's for even more weight savings. It's good to know Buddy RC is here with a great brand and plenty of inventory supply to keep me going on all my builds.

Good motor for Twisted Hobbys planes Review by Russell All my reviews  (2)
Overall Rating
Used this motor on my new crack laser from twisted hobbys. The motor performs wonderfully. The plane can hover at around ~50% throttle and had lots of power to do 3D maneuvers. The only downside to this motor is that the prop saver attached to the motor doesn't fit GWS props very well. The motor comes with a small aluminum adapter ring, but that tends to fall off very easily. If you lose it like I did, you'll have to use an extra tight rubber band to keep the prop from wobbling. Easy to add a new rubber band though -- not worth detracting a star. (Posted on July 28, 2013)
