Emax ECO II 2807 - Thrust Tests & Flight Footage

[@mantyfpv7409]

I love how they come with a bunch of different size motor screws

[@KremerFPV]

Yep, that's handy.

[@EnglishTurbines]

Looks like your rainy season...but with sunshine..Motors look very nice...🤔😀🇬🇧

[@KremerFPV]

Haha, it was raining for a bit in the past couple of weeks but the sun is back ;-)

[@ronbo422]

Gal, thanks for the test data!! I'm in the middle of a 7" long-range build with the Eco ii 2807 1300's (on 6S) and see that this thing has the potential to make some big power. On 7056 props, the quad should "sip the juice" of the Li-Ion packs I have planned on building. I'll be using 6S2P Molicel P42A's, which should be good for 35+ minutes of easy cruising :-P

[@KremerFPV]

My pleasure buddy, Sounds like fun!

[@MCsCreations]

Fantastic flying and review, Gal!!! 😃 Pretty impressive motors! I loved them! 😃 Stay safe there with your family! 🖖😊

[@KremerFPV]

Thanks Mario, you too!

[@andrewjamez]

would the 1500kv be better option if you want to fast cruise on 4s and the odd beat up on 6s? maybe with 6" prop on 6s...

[@abhiramreddy4849]

very nice video gal there were no videos about the motor which i could trust,i am going to use these motors on my 7 inch build parts-tbs source1,eco2 2807 1300kv,rush fpv tank solo,caddex ratel,lumenier axii,mamba 60a f7 stack,radiomaster tx16s,frsky r9m. would this be good or should i change something

[@KremerFPV]

Thank you! I am happy I can provide you with reliable motors tests. As for your setup, It sounds great. I am used to Crossfire but if Frsky r9m works for you, that's good and I don't think that you need to change anything. Enjoy your new build!

[@BlackbugDigital]

Hello! I have these motors and my AUW is 1.6kg on a 7" prop running 6s. It flies fine but do you think I need to upgrade to a 2808 motor? Others say quad is too heavy for the motor

[@Bashash911]

Hi Gal! Love your work. Those thrust tests are REALLY handy! Do you have a spreadsheet of all motors results? Something like that would be super useful ! bty, I live in Israel too.. ;)

[@KremerFPV]

Thanks Barak! I don't have one yet but it's something that I plan to do in the near future.

[@Juliomartinsfpv]

[@KremerFPV]

Thank you!

[@maxagostinelli8607]

hello thanks for the video, what esc do you recommend for emax 2807 1300 kv on a 7 inch with li ion 6s? thank you

[@Diown]

great tests like always! are you planing to test the brotherhobby 2806.5 soon? I'm interested what is most efficient for a 1.7kg drone from 7" until 9"

[@sasaamisi]

I'm a bit curious as to how the 5s setup works best? as I see it 6s has less current draw for the same thrust... high throttle draw is a problem but you won't really get there with these numbers. asking from a long range 7 inch perspective in mind, prob liion 6s2p. am I missing something obvious - must be ;)

[@KremerFPV]

I am sorry if it doesn't make sense, but that was my experience. There are also more variables like battery size and type for example so you might have a different experience than mine :-)

[@sasaamisi]

@@KremerFPV absolutely agree, there's more to it than a static test can show. Will def try the difference. And don't get me wrong, love the video and this super informative test. Keep up the great work and have fun flying

[@KremerFPV]

@@sasaamisi Thanks man. I would love to know what you think after testing it out.

[@tahmidurjahan8204]

The review was nice. I was trying to build a 7" quad. Using source one frame, Velox V45a esc, Hglrc F722 FC but i was wondering which motor and battery type to choose for optimal flight time for a freestyle quad. I like the emax eco so what kv should i go for? And i have a default capacitor with the esc, is it ok or i need to buy new capacitor?

[@KremerFPV]

Thanks. I would go with the lowest KV option and the default capacitor is ok. As for battery, a 4s 4000mah or similar should be good.

[@tuckerfarce]

I was running the 1700kv on 6S with Gatebreaker 6x5x3 props and they were really happy. Never got hot. (I’m at 5000ft/1500m above sea level, though)

[@kwadkrazy6078]

Thinking of doin the same thing, what voltage did you run them at?

[@tuckerfarce]

@@kwadkrazy6078 6S, so roughly 25.2V. They’re power hungry, so a rock solid esc is absolutely necessary.

[@KremerFPV]

Thanks for sharing your experience Tucker. I could have pushed the motors more in the test and unfortunately due to time constraints I didn't even test all the KV options which I normally do.

[@DidinAhmadi]

can it be use for propeler 5 inch for long range purpose with 45A ESC?

[@KremerFPV]

Yes.

[@flywithtb5005]

Whats you all time pick for a 7 inch maximum efficiency long range cruiser and best overall option?

[@KremerFPV]

Tough question. I don't have a lot of experience with 7" motors. I am going to test the Tmotor F100 soon. They should be pretty efficient as far as I know.

[@flywithtb5005]

Thanks for the suggestion, I will check it out.

[@MrPhilbautista]

Any prop/motor suggestions for lifting a heavy load on a kwad? Looking at around 2 kilos including the weight of the kwad.

[@KremerFPV]

Each motor should be able to lift about 500g, preferably a at around %30 throttle more or less. This motor on a 7" setup should do the trick. Keep in mind that the battery is pretty heavy as well.

[@rolisaenz]

Hey buddy, those are for an 7" or 8" LR rig right ? Dalprop 7056 with 4S all the way, that was the overall most efficient combo with the 1300kv motor you show the graphs :)

[@KremerFPV]

Hola amigo, true. With 8" props it would have been probably even be more efficient but I unfortunately I didn't test this setup as I don't have any.

[@rolisaenz]

[@eaglewings1318]

@Grim FPV Hi! What is your feedback for these 2807 motors with 8 inches props?

[@eaglewings1318]

@Grim FPV yes tell me when you'll test it :) thx

[@mikeevans6926]

Looks like it needs a little tune adjustment but that thing is rowdy on 6s. Well done sir

[@KremerFPV]

Thanks Mike. Sure, I flew it using BF stock settings and I think that it was quite OK, but some little tuning could have made it fly perfect :-)

[@zaido8735]

Hi Gal I like your reviews Thanks for these results you helped me a lot. I want to consult you on something. I want to carry AUW about 3.3kg for max 3 mins. I’ll use 7 inch props and 6s battery. I want to make drone as light as possible. But I hover between Emax eco II 2807 1300kv and T-motor F90 1300kv. Numbers are shows emax eco better than T-motor F90 but I worry about quality of emax ecos for this task. Which one do you think makes more sense to use?

[@KremerFPV]

Hi there! I think that the quality of the Emax Eco II is good. But if you want to stay on the safe side and you don't mind spending more - go for the F90.

[@yannickg6904]

What?! No DJI drone? lol Probably my next motors if I decide to build a second 7 incher. Thanks for the review, Gal.

[@marc_frank]

so how many would you buy?

[@yannickg6904]

@@marc_frank 6 is always my minimum, maybe 8. I have 2407s on my current 7in, they do not handle 7in triblades well. I need to downprop to 6in to avoid jello. Considering the size of the stator, these Emax motors are an incredible value, they charge very little more than the other Eco II sizes.

[@yannickg6904]

@@marc_frank By the way Frank, I ordered the Flywoo Hexplorer stack...😉 I looked at my Cad models again and a 3in or 4in hexa is just too big, as large as a 5in.

Nice review, thanks 👍. I have those motors (1300kv) on my bench for several weeks now, never installed on a quad, they are on the heavy side compared to some Brotherhobby 2806.5. Maybe I will install them on a 7" "crash" drone.

Hey gal, not sure if your still responding to comments, but do you think that running 1500kv on 6s is safe on a 50 amp esc? Right now I'm about to run Dal 6048s before I try any 7 Inch prop out of fear of drawing more than what my ESC can provide

[@KremerFPV]

Hi Mark, sorry things were pretty hectic recently, but I am still responding to all the comments on my videos. Yep, a 50A ESC will be fine. If you are worried about it I recommend to set the motors output limit to 90%. Have fun!

I have the 1700kv ones on 6s batteries. Shes fast just not efficient and they draw around 150 amps at full throttle according to my OSD. Youll get short flight times. I got around 4-6 minutes on 1500mah6s lipos freestyling, and 10 minutes flow flying at 30km/h

You could reduce the motor output to 86% which will basically make the motors 1300kv. Just an idea :)
