Testing FETTECs new PROTOTYPE ESC against BLHeli_32 AM_32 and BlueJay 

Bluejay being so cheaper, it is really shining there! 😄

does changing the timing on the ESCs make any difference to these results?

I would recommend measuring current consumption on all tests.

It would be very interesting to see that different settings on the ESCs will change on this tests. The fettec ESC has probably just more aggressive default settings.

Seems like the speedy bee esc is kinda the best price to performance

Great video. The flywheel testing is very helpful for people in combat robotics.

Excellent testing, Chris! Thanks a bunch! 😃 Stay safe there with your family! 🖖😊

Wondering why you haven't included noise as Drone Mesh used to do, I'm still on analogue and noise in my camera feed is probably the main thing that puts me off certain brands/esc's.

Thank you very much for showing this test. I am not using drones, but have started to look for different solutions with BLDC motors, and it have been hard to find specific information on how different ESCs perform regarding speed step response. I do however have a general good understanding of electrical motors. Your information here is the best I have seen so far. You and few other RU-vidrs have provided information on how the choice of motor do influence the response time, that you like to be fast for good flying performance. But it is interesting, that the choice of ESC also makes a difference. When I study the breaking performance, I should think that there should be room for improvement for all the ESCs, and especially the new FETTEC ESC with better current sensing should be able to do that. So perhaps they will do it in future firmware versions. With acceleration you got some natural limits, and perhaps it might not be possible to do it much better than shown.

The testing is great. After the stress test with the flywheel, a temp comparison would be nice. The cutoff voltage of each is needed too.

I would also include electric noise as a parameter. This is also important for the other sensitive electrical components in the quad.

I'm sorry, but.. what exactly does this testing show? That ESCs manufactured by different parties, with a different Amp-rating, running different firmware, at a different age - perform differently? Did you expect different?

Very good job!

thank you my friend

Thanks Chris for the test. The result of Bluejay ESC really impressive compared to the price of BL_32.

Thanks oracle🙏🏻

I guess one thing that wasn't mentioned would be are these ESCs just on default settings? Or was there certian things done in the settings to help out as best as possible? Also another ESC that would be interesting to see in the mix would be Advanced Power Drives (APD). They're more common with xclass and heavy lift cinematic rigs. But like FETTEC and Flyduino, APD uses closed source software for it's ESCs.

Would it be possible to extend your flywheel test starting from 0 RPM? Really curious to see the differences there.

Please include ESCape32 fw in the testing!

How about adding some measure of efficiency? Perhaps compare current draw at some standard RPM on some standard prop. Or perhaps spin a generator and plot power consumed vs power generated with a sweep over RPM?

I afraid energy in the capacitor is negligible in the context of flywheel. It can only help with peak microsecond current spikes... Supercapacitor bank could have helped with 200A loads :-)

Really interesting work. I know, it's just asking for more - but - I'd be interested to see if the performance remains the same when all 4 outputs are performing the tests at the same time. Do you think that it's worth normalising the results for the last test due to the different current capabilities of the ESCs? The FOC approach seems to generally be advantageous on the T-Motor Alpha ESCs so, I'm not surprised to see that FOC performs well at the FPV scale.

It looks like on your chart the SpeedyBee gets the edge on the last test. I do see the new FETTEC overall doing better but how much of a difference will that make in actual flight? Just a thought.

I would love to see Tests with the new Flywoo Goku F722 Stacks 😊

Could you you please add the settings used on the ESCs to the description? (especially the decreasing resolution of the bluejay-ESC in the rampup/down smells like 48kHz was used)

Please test the FrSky Neuron 2, AtomRC and sequre ESCs. Thank you.

ok ok waiting for the new Fettec ESC I hope it will be good for KISS Ultra v2

Would be great to add thermal footage of the ESC as well. :) budt otherwise perfect testing

the contrast becomes nigh/day difference the more demanding conditions. I'm humbly surprised at how well the speedy bee esc did

In future testing can you include the flywheel test from a dead stop to full speed? to test the sensorless startup performance. Does it cog at all? does it spin the correct direction on the first try?

How did this compare to a vesc using simplefoc?

Put the threshold to 85% and the outcome is different. Actually only the Blheli32 ESC is significantly slower. The rest is +/- the same in my opinion.

Great system engineer test, as always Chris. But let me ask the question to Responsive - Acceleration test. Is the FETTEC really the best in this test? It can reach the 90% level faster, but I suppose overall generated thrust is bigger for Speedybee ESC - when you calculate area under the curves.. btw. can you keep same colors for ESCs in charts? :)

i wonder how will the new speedybee 60A will perform.

I wonder if there is actually any battery for FPV drone that would be able to fully power all 4 motors at 100% throttle as those ESCs are actually capable of?...as I understand those 55A ESCs can deliver 55A of continuous current per motor...for example my Wasp Major datasheet says that it takes about 30A on 100% throttle...that would be 120A in total...I see that those ESCs should handle it without any problem with huge margin but can any battery at standard capacities 1300-1500mAh even deliver this power? Especially considering that the C number is a marketing bullshit and real C number is usually like 1/4 of the advertised? So even Tattu R-line with 150C can delived just about 40A continuously which is only 10A per motor and shortly maybe 100A which is just 25A per motor and it sags quickly...I tested CNHL Black 1300mAh to push it to the limit and it just capped at 84A and didn't go higher, which was barely 20A per motor, which is 2/3 of its max power...

In all the tests is possible that the fettec esc is winning because has more amps rating? It s a fair comparison?

Any chance you could verify the ESC's aren't lying in their telemetry data as part of future testing?

Why is the foxeer 65a reaper not in this test which is considered to be one of the best 65a ESC’s out there?

Why do you not do the math to show the torque vs RPM curve (and power), after doing the inertia dyno pull?

The FETTEC rpm data looks concerningly clean. I would take a look and make sure they aren't sending the RPM setpoint over dshot and not the actual measured eRPM.

The FOC motor control should be audibly quieter than the traditional trapezoidal control. Probably where the efficiency is gained; less power lost as sound

Analytics!

As expected, these days electronic is on so high level that differences are cosmetic IMO. What you can really compare is EMC performance, like resistance for some electrical shocks while unprofessional user is setting up a drone or, even more interesting, EMC emission (conducted, radiated) to check real impact on other parts of setup...

Three cheers for Bluejay!

Just installed the speedybee the other day(actually it's the newest 60A version), nice to see how it does considering the price. Thanks again Chris, for all you do!

how is the result in this video is so much different from the last sec test video you made?

what about efficiency?

Unquestionably the best channel at indept research 👌.

Mr. Rosser Im so enjoying my AOS EVO 7 Sir so Thank You!!!! I also have the 5.5 and love it equally as well!

wen cine35 best motors review?

❤

I hope it works for Betaflight, gonna negate all that performance having to use KISS LOL

Xrotor are the best ESCs in terms of durability - I would recommend testing these.

Great work Chris ! Finally someone that is working hard to go deep in testing fpv hardware and share the results. This is gold for the fpv community ❤

I would argue that 10ms of acceleration delay is not comparable to 10ms of video link latency. You're talking about 10ms to get from 85% to 90% rpm. It doesn't result in anything close to the pilot seeing where the quad was 10ms ago like you get with video/control latency.

Could you please zoom in the interesting parts of the charts? Throttle ramp chart below 50% is totally uninteresting after seeing it's basically the same. The magic happens where we can't see any difference, because it's so tiny

Felix is a genius

FPV JEDI!

Am32 is at 2.08 firmware now.. it performs a bit different to 1.99. The other esc’s are all running modern firmware

🧐👍✨

This is similar to the promotion of FETtec equipment.

You might want to update AM32, that's quite an old version.

Sorry Chris but I'm very confused about this testing. What exactly are we comparing here? You have different ESC hardware, different firmwares and even different sizes. You have 3 variables here. Even within the same manufacturer they sometimes change parts due to availability adding even more variables. With BLHELI32 and AM32 it would be more interesting, imho, if you flashed them to the same ESC. Unfortunately with bluejay I understand that's not possible. You also don't describe what settings you are using, they could vary wildly. Lastly, if the goal is to then test different ESC hardware it should be run on the same firmware, no?

My question is, why wouldn't he compare it to the existing 65 amp ESC from fettec?

I really do appreciate all of your testing an most of the time I respect your methodology. But here you present this as a test of firmware but your testing is extremely flawed with such a variation in ESCs. Maybe you could repeat these tests with a few ESCs that can be flashed with different firmware so that you can verify that it is indeed the firmware that is consistently responsible for the variation in performance

The only thing I want is cheaper kiss stuff I’m not impressed with fettec feel

Funny how the one esc that has over a 15% higher continuous amp rating then all the others has slightly higher acceleration... Why do these tests never seem to have equally matched up test subjects??? I'm sure the fettec fan boys are clapping like seals... Now lets make them cry and do overload and sudden stop testing where you repeatedly do heavy load accelerations a bunch of times but then add a brake to slam it to a sudden stop under load to simulate a prop strike crash scenario to see which one fails first...

Motors xnova

I don’t trust this dude can’t even fly just another bard well getting ur view money
