SunnySky EDGE 2204(4.6) 2300kv Full Results  [CLICK HERE]

 

This motor is the long awaited re-entry of SunnySky into the miniquad world.  This was the first release in the EDGE line, and has some interesting points.  Thanks to a friendly supporter for loaning this one to test.

Summary

After the success of the SunnySky X2204 in the early days of miniquads and FPV, SunnySky disappeared for quite a long time, releasing the X2207 motors, but largely ignoring the small miniquad scene.  After some time the EDGE series of motors hit the market with some really interesting innovations.  The biggest one was probably the screw instead of a C-Clip on the shaft, as well as the unique single-peice shaft design.  The windings are silver instead of copper supposedly due to a siver plating.  Based on what I've seen it is largely cosmetic though SunnySky does seem to make some claims to the contrary.  Also interesting to not that this motor uses 23 0.2mm stator laminations, which makes the stator height 4.6mm, though SunnySky has still chosen to categorize it as a 2204.  It is the same stator height as the earliy RCX H2205 series motors.  Under the product details SunnySky does state the accurate stator height however, so I feel they are still accurately representing their product.  The build quality on this motor is impressive, as I would expect from SunnySky.  The bearings are extremely smooth, and everything is very solid.  The motor weighs in at 27g, which is not bad for an almost 2205, but still a good deal heavier than their old X2204. With the solid shaft larger size though it is no surprise.  The weight issues seem to have been addressed with the release of the Edge Light motors, which I hope to snag for testing at some point, along with the larger stator sibling to this one.

Now on to the bench results!

Test Results

Given the N45SH magnets and slightly shorter stator height, I was not expecting massive thrust from this motor and it performed about to my expectations.  Test results are very close to the Cobra 2204(5) 2300kv, outscoring it a bit on the 4" props and matching or exceeding it on the heavier 5 and 6" props. Given that the measured KV is closer to 2400kv this makes a lot of sense.  Tighter tolerances, higher KV, and a closer airgap in the Edge seem to have essentially made up the difference of the two missing stator laminations between the two motors, and they are very closely matched.  The most notable thing about this motor is how extremely smooth it is.  There is an audible difference on the SunnySky motors over almost any other motor I've tested. Overall this is a very solid motor, but not a high horspower racing motor.  Smooth is where this motor wins.  

It's also worth noting that on this test I replaced the Diatone Ghost 5x3 with a new prop, the Lynx 5x3. The Diatone Ghost was giving me fits due to lack of balance and durability.  It shattered on the stand several times, and damaged some equipment. I was sent a sample of props from Lynx a while ago to test, so I decided it would make a good replacement.  It doesn't appear to be as efficient as the Ghost, but it does put out some good numbers for a 5x3 and is definitely better balanaced.
