If you're a manufacturer (or a pilot!) and would like to send me a motor to test and add to the AOS Labs charts please get in touch on aos-rc.com 👍

Chriss revenge to Mr Steel talking bad about AOS 5. xDDD

[baggszilla]

Unbelievable work Chris like always!! We need a video showing us how to flash our BLHeli_32 ESCs to AM32! Thanks and Cheers!

Glad to see others focusing on motor and propeller testing. Great work! The message that's been propagated saying that motors and propellers of the same size and pitch have a negligible difference is so untrue. One observation I've made when measuring Kv is that it is very important that you do the test really quickly (burst and measure) since heat will build up under no load and start affecting the accuracy of the test. This is probably less of an issue on larger motors with a lower Kv, but it makes a huge difference on smaller ones.

in other video, mr steele says aos frame is complete b*llsht
and in this video, you say mr steele motor is b*llsht
this is elegant wars..
love it

Absolutely brilliant content! We are lucky to have a guy like you performing these awesome scientific tests and publishing the results. This will hold manufacturers to their word.

RCInpower have been my favorite motors since about a year after I got into quads, so like 5 years or so. Now I can see some data that proves it wasn't just a placebo effect. Thanks Chris!

Awesome video as usual Chris. Correct me if I'm wrong but as a budget drone builder my main takeaway is that the Emax ECO 2207 gives a really good balance of responsiveness, torque and efficiency which IMO is decent value for money. It might be worth normalising those scores by cost. 💸

This is exactly the kind of testing we needed in the community!

An interesting test could be you putting the best motor-ESC combination against what was available back in 2014, Emax MT2204 and a simonK ESC, and similar combinations

[dutchfpv]

Separating the science from the hype. Phenomenal work. You continue to confirm our suspicions and open our eyes to new information to put to use. Please keep doing what you're doing. It really empowers the community.

[MrChangCJ]

thank you for doing this, and sharing your results so freely. this pushes the industry forward as OEMs know they are under scientific scrutiny.

[z-collector]

Thank you for all the hard work! Great test, very informative video. Mr. Steele must be shitting bricks by now :)

[madtoffelpremium]

Seeing how solid the Emax Eco 2 is, I wound love to see how the other budget option, the Xing-E, performs.

[mhe]

This is so awesome, thanks for going through the trouble of performing all these tests and getting us all that data!
On a sidenote: This must feel pretty darn ironic but good for you, given how Steele talked shit about the AOS 5 when it came out...

[billyocean]

Amazing testing. Truly clinical. I am thankful that the hobby has your support and interest.

[SpringHaIo]

To get an exact comparison of air gaps you could measure the stator and rotor diameters with calipers. I'm glad you're doing a true inertial dyno test in addition to the usual prop testing because it really does give you more objective normalized data. How many averages did you do for each run? The data still looks a little blocky on some graphs and the efficiency one is pretty hard to decipher. Cheers!

[alexanderg-pz]

A lot of weights gave their life for this device.
Exceptional video by the way!

[HeroRc]

Chris, thank you for all the effort. This is a liquid gold kind of content.

It would be also useful to see the price adjusted score

[RyanQuellet]

Very informative. Please test the Five33 1960kV 2207 motor most of us use for 5in racing (it's also a spec motor for freedom spec)

[MCsCreations]

Really interesting results indeed, Chris! 😃
Thanks a bunch for all the testing!!!
Stay safe there with your family! 🖖😊
