Class Leading Brushless: How is this possible? Sunnysky x2216 1250Kv v3 [The Judge Ep. 11]

This is the rcvideoreviews.com power and thrust test of the Sunnysky x2216 1250Kv v3 Brushless motor.
I don't know what's going on over at Sunnysky, but there is some magic in these little 70g motors. Power development is stunning.

Excellent cross-examine with The Judge....and Sunny Sky seems to be in possession of the secret sauce! 👍🏻

[@RCVideoReviews]

They beat up other motor in their weight class. I don’t know how else to put it.

Thank You. From Frisco, TX. Valuable data to me and takes a lot time to make this content.

[@RCVideoReviews]

Glad it was helpful! Thanks for the comment.

[@BryonGaskin]

This videos are awesome. Most newbies like myself probably don't have the setup (and knowledge) to do this these types of tests when we first get into the hobby. Then one day they crash their model or something just breaks/burns up. They go looking for a replacement motor.......opps not available. Then they are like, what else might work so they go off trying to find a replacement motor but don't know how the motors compare even though they motors look similar in terms of size and kv.

[@RCVideoReviews]

Glad to help. Sadly, these videos never got much traction so I rarely do these tests for the channel anymore. There simply weren't enough views to justify the work I put into them. Anyway, there are a lot of "Judge" videos on the channel if you want to watch more of them and learn some of the evaluation techniques I used to assess motors.

[@SIDICOMP]

really enjoyed the test you did version 3 and version 2. It helped me a lot to choose an engine for my plane. Thank you

[@RCVideoReviews]

You're welcome. Thanks for commenting. V3 are the best, but V2 are still excellent. You can't go wrong with either one.

[@tristanchadderton6062]

Im using the 1400kv version in my 38" 3D plane on a 10x5" prop. I get around 600W peak. Absolute beast of a motor

[@RCVideoReviews]

Yeah, that's stout.

[@deanedeane4318]

As always a great interesting video !!! I'm a massive fan of sunnysky motors , for me currently they're the pinical ....... I'm wandering if the small machined scallops are to help dissapate heat since it's not far from the bearing ..... Thankyou for the closing time bloopers !!!😁😉😎

[@RCVideoReviews]

Glad you found the bloopers and enjoyed the video. Sunnysky is really good.

[@deanedeane4318]

Yes and if you look at what companies are using sunnysky it's mostly going into really good stuff 😉😎

[@dougmcpheters1546]

The Judge, all will be revealed!

[@RCVideoReviews]

Yessir!

[@jacksampson7711]

Wow I've never really looked at motor that closely. I have order pretty cheap motors from ebay and amazon and can definitely tell when I get a good quality motor. This one looks pretty nice.

[@RCVideoReviews]

Sunnysky motors are excellent especially considering their price. The v3 motors are world class in my opinion.

[@kermets]

Would be great if you had done a couple of stepped throttle positions, say 300grs thrust as that could be a long range cruise setting on a wing and 500gs etc etc......

[@kevinflores105]

The judge is the judge

[@RCVideoReviews]

Heh, yeah it is.

[@kf4293]

Hey, any chance of testing the SunnySky Angel A2216 motors? Doesn't seem like there's anything on them available.

[@fishboy77]

1250 Kv motor was actually 1446? That's a huge difference. No wonder it got so hot.

[@RCVideoReviews]

Yeah, curious it spun that fast.

[@Lunarpollo5622]

Can this motor be used for rc boat prop application? The prop is like 25cm in diameter, I'm not looking for a fast boat just one that goes from point a to b without getting bogged down too much

[@RCVideoReviews]

You have to figure out what your load in amperage will be and compare it to the motor specifications to see if it can handle the amperage you intend to load.

[@stewm400driver]

Thanks for another interesting video. I was looking for a motor that had as an example a 28/32 putting out 220 watts. This looks even better , but why the difference in labeling? I guess I need to look at what output i need and work back from there. My suggested was a pretty poor one from the World Models-KM28321030. This looks to be a much better option for my old Sunrise EP.

[@RCVideoReviews]

This is Sunnysky's v3 line. It is a beast of a motor. Watch some of the Hummer videos and you can see this motor launch the Hummer like a rocket from a hover. I'm gobsmacked at how good this little motor is.

[@danmor6579]

I love these Sunnysky engines

[@RCVideoReviews]

The v3 is impressive. I'm looking forward to flying it.

[@gradenko23]

Hi, I intend to put this on a Skylark-S foamie pattern plane. Would this motor fly it decently? Im very new to electrics so feeling my may in it. I fly mostly glow and just converted. Thanks.

[@jwpw47]

Many thanks for your magnificent video tests. On the basis of which I bought a SK x2220 v3 1400kV: a great motor. Do you know how to mount a prop on the axis instead of mounting it on the adapter that is in the box?

[@RCVideoReviews]

I haven't looked closely at this motor, but they generally have one or more grub screws holding the housing in place on the shaft. If you release those grub screws it's not too hard to press the shaft so that it protrudes out the other end of the motor. Then just tighten the grub screws again. Be aware you may have to install c-clips to keep the shaft from pulling out under power.

[@MikeWedding]

Would a 10 x 4.7 APC slow fly prop with a 40A ESC on a ~1.5lb plane work? Their site recommends a 40A ESC, but shows 42 A max current draw. Thanks!

[@RCVideoReviews]

You need to measure with a watt meter. I personally don't like cutting things that close.

[@MikeWedding]

@@RCVideoReviews Thanks so much for the reply. Wasn't expecting it on a 2 year old post. I agree. I think I'll go with the 1100 KV to reduce the amps and heat. Thanks again!

[@tristanchadderton6062]

​@@MikeWedding I run my Hobbywing 40A platinum ESC on this motor (1400kv version) with a 10x5 3s and pull 55A. They are rated for 60A for 30 secs. If your model is light and the ESC has an ok amount of air it shouldn't be an issue. Using a non name brand 40A could be a different story though.

[@robbyrock-drummer]

Very nice.. Have you look at dualsky motors?

[@RCVideoReviews]

I'm aware of them. In the countless number of searches I've made for brushless motors they never showed up on my radar. I've been able to meet my needs with Sunnysky V3 or Cobra for about 99% of what I fly.

[@robbyrock-drummer]

@@RCVideoReviews I was impressed by the Sunnysky V3 and going to order the 1100kv to use in a Inside F5J on 3s and with 12/6 folding prop.

[@airhammer6203]

Very nice motor. I wonder how it would do with a 10×5 reg. prop? Is the heat going to be detrimental for it's longevity, or is it designed that way? I was wondering, how are you liking the Brew. Buffalo? AirHammer out!!

[@RCVideoReviews]

I think 9x6 and 10x5 will wind up very close in terms of demand and amperage. I am a little concerned about the heat and will be monitoring that situation. I need to take the Buffalo out again soon. It’s a fun little fast plane. So far so good.

[@airhammer6203]

@@RCVideoReviews I told you the Buff was fast! I need to get mine out to. This plane is why I was asking about the 10×5.

[@nathandsouza4716]

Love your video. Thanks a lot for it. Based on your experience, how hot does it get with the 10x4.7 prop for continuous usage? And what would be the safe prop to use? (I mainly plan on using it for 3D) Your advice would be much appreciated. Thanks!

[@RCVideoReviews]

I've flown this motor on my Hummer in 3D quite a bit over the summer in Florida and it didn't have a problem.

[@nathandsouza4716]

@@RCVideoReviews Thanks! So i dont need to worry about the motor overheating right!

[@Blackfarmerunion]

Would this motor mount flush to the Skylark? I’m having troubles mounting my leopard 2835 the shaft is too short and I don’t want cut the foam. Thanks!

[@RCVideoReviews]

Can you get a couple of standoffs? Or even a few washers under the cross mount? I don't know how this would fit without measuring. But don't be afraid of standoffs.

[@staydown.normal5323]

i want to buy a sunnysky 2400kv motor for my sonic modell pro it comes with a 1400kv motor... the 2400kv motor should have more power yes????

[@RCVideoReviews]

That's not quite the way it works. 2400kv will spin faster, but you'll need a smaller prop. So it will likely lose power but gain speed.

[@staydown.normal5323]

@@RCVideoReviews i bought the sunnysky 1400kv v3 motor. and replaced the 1400kv stock motor they get hot and dont have as much thrust ass the v3

V3 are my go to motor right now.

[@cyprienbrun8075]

Hello, thanks you for this test. Can you share your all motor data in Excel file? I think it will be more easy to compare. What do you Think?

[@RCVideoReviews]

I started logging all of the motor data and offered it, but nobody seemed interested in it so I didn't keep it current.
