EMAX ECO II 2807 bit.ly/3cd4n7l
Big quads need big motors. EMAX ECO II 2807 is my new motor for 7-inch propellers. Plenty of torque, power, and very reasonably priced!

[@maceliusfpv370]

Nice to have some affordable 7" motors, hope some others follow suit like Lumenier with their Chief series. "flippidy floppyness factor" should be an official rating.

[@ImperialArmour]

2x more responsive flight performance is more exciting than 2x flight time for sure.

[@visioneerone]

literally starting the build of my AOS 7 tonight. I strongly considered these motors but they were out of stock like everywhere! Ended up purchasing Hyperlite 2807.5 1322kv motors instead. torque is good. torque is Life.

[@MCsCreations]

Fantastic, Pawel! Thanks a lot! 😃 The quad really seemed much faster! Stay safe there with your family! 🖖😊

[@itaysteklov1241]

Emax makes some impressive stuff for an awesome price, I am using the eco II 2306 on my 5 inch and they are amazing

[@muhammadyahya8392]

Same, used them on 2 5" quads

[@erlandfpv]

Hi, yes I'm choose 2306 too for my new build 5inch quad.

[@dronepilot260rc]

I just ordered these. Thanks!

[@chrismel9000]

Great video, Thanks for the reassurance. I just ordered the same 1700kv's for my 4s 7in Source one V3 Deadcat build. Good to know I made the right choice.

[@k1ortia]

Emax are not messing about with thier eco series motors.

[@FJamesPrice]

I got these for my inav 7 inch in 1500kv and they're great. Still I'm getting a little wobble but probably has to do with bad magnetometer mount. It flies fine on 4s or 6s but seems to like the 6s a little more. I've also noticed the APC B7x5E-B4 props cause these motors to run much much cooler (and they're much quieter) than for example HQ Prop 7x4.5x2 or HQ Prop 7x3.5x3 V1S Tri-Blade.

[@sus7382]

Hey! I've got 1500kv on 6s too, how much does yours pull? I've got a 50a esc and I want to use some gemfan 7040 triblades

[@supernova1969a]

So that's it.. My AOS 7 gets EMAX 2807s!!! Thank you!!

[@FPVUniversity]

I have now 16 of those motors operational on my drones. So yeah, good motor

[@brubakerjm]

Happy to hear this report. My 1500KVs just go delivered for my Hyperlite Floss 3.0 7-inch build. Thanks, Paweł!

[@TheOneAndOnlyRandy]

I have several builds with these motors onboard

[@ronbo422]

I use these bad boys in my new 7" build...the 1300kv versions. Nice and smooth on 6S. So glad I didn't waste money on more expensive motors. :) = more free cash for Li-Ion cells! Did you think that those DAL folding 7's are more efficient over my current DAL 7056C's?

[@alexall]

Bearings on these motors make you cry after a few flights

[@Mr_Eyeholes]

Could you please elaborate?

[@alexall]

@@Mr_Eyeholes The motors are good in terms of efficiency. They fly quite fast, I accelerated a 7-inch quadcopter on 1500kv motors with 5s 3000mah batteries to a speed of 175km / h. On assemblies of 18650 2p 4s accumulators during slow flight, it flies for 30 minutes. But the bearings began to make noise almost immediately. Had to be replaced, the size of the bearings is 4x12x4. and this is not a coincidence of poor quality. I have two quadcopters with 1300kv and 1500kv motors and all 8 motors had to be replaced with bearings.

[@Mr_Eyeholes]

@@alexall - Thank you, good to know. Also, those are some impressive stats!

[@mariusztv4339]

They are now discounted on aliexpress :)

[@user-dj6qp6kd5t]

Ha! My Emax 2807 1700 are smiling at me right now from the arms of my 7-inch quadcopter hanging on the wall!

[@raven_fpv]

WOW that is soooo crazy because I have those EXACT motors on my freshly built iFlight XL7 7 inch quad running iNav!!! I still have to maiden it. Awesome Pawel. Now I think I will be buying more of them for other 7 inch projects! Do you have a video on a 7 inch running iNav as far as what set up you use in iNav? I would love to do a 10 inch quad running iNav some time!

[@carlosfuhrer]

I have these motors on my FR7 inav build and I love them Pawel please do a tuning session using these motors for 7 inches drone

[@harpalyke4659]

I've got the 1500kv version of these on my 7 inch SourceOne build. There amazing, but I did see some slight shakes when cruising at mid throttle. I gave the 7 inch tune preset from theuavtech website a go and it worked wonders. Its worth giving that a go as a base tune.

[@swissfreek]

I love these motors on my 7”. Are they different from other 2807s? Maybe? I dunno, BUT they are like half the price of similar motors (I got mine when they were on sale for like $15 per motor, couldn’t pass it up). And they look great in my opinion. I got the 1700kv as well, works for 4S, if I want to fly 6S I just use output limit (yes I’m still on BetaFlight).

[@loganwinheim7695]

Pawel, I was torn between these and the BrotherHobby 2806.5s 1300 kv on 6s. I had an accident where a prop nut came loose on my last aircraft (very sad). Needless to say, I am in the market for new motors. Thank you very much for all of the knowledge and insight you provide to our awesome hobby.

[@adam_seal]

Hi Pawel have you seen the Xing 2 3106 motors, and can you do review on it because I haven't seen anyone who has done it

[@elbedouirayen7938]

Thank u for everything, and please can these motors carry a 650 gr camera?

[@BBFPV]

It doesn't look like the quality is even roughly comparable to the BrotherHobby Avenger 2806.5. The coils look like I'm winding a water hose.

[@FPVUniversity]

The winding is indeed less pretty than competition offers. But I have 2806.5 and have to say that over all I preffer ECO2 as smoother motor

[@audiogek]

First! 😂 Locally still affordable luckily, BG is asking a premium price for them now.

[@FPVUniversity]

Yeah, on the "first" topic. Looks like I lost all the comments due to the hacker attack during the weekend. I mean, comments kind of exist, but are not visible under videos

[@paulodinis1981]

Hallo Pawel Im gonna build a 7inch drone and im not shure what motors to choose. Im thinking on using my 3s 5000mah batteries but not shure if its possible to use those batteries or if possible what kind of motors to choose. Can i have an advise from you?

[@h2o-fpv623]

Great stuff thank u

[@risgrigg]

Are you using soft motor mounts or is that not necessary with soft flight controller mounts these days? Thanks for all the great videos and advice!

[@FPVUniversity]

soft mounted motors are so much 2017. Don't use them

[@risgrigg]

@@FPVUniversity Thank you!

[@TERBANGFPV]

pavel, how the emax eco motors after doing several flight? still smooth and good bearing? or already cruncy bearing?

[@FPVUniversity]

No problems so far.

[@TechTimeElectronics]

Well I don't get is that why is the mounting pattern for them 19 by 19 and then I get to 7-inch diatone Roma and the mounting pattern on the 7-inch arms is 17 * 17

[@FPVUniversity]

In general, it's a problem of a frame. It's 100% possible to have elongated holes that accept both patterns 17x17 and 19x19 plus a variation of 17x19 with is also popular.

[@TechTimeElectronics]

@@FPVUniversity yes it's kind of upsetting ordering a frame from China to the United States and I have to alter the holes on the frame in order for the motors to fit. I can see if it was a 5 inch frame I'm trying to jam those Motors a lot but this is a 7-inch long range Roma F7.

[@Pukkaras]

Dalprop fold - no no no! The most shitty props in comparison with gemfan flash 7042, hqprop 7045, dalprop 7056. Dalprop Fold 20% less efficiancy then flash, more vibration on throttle movement, more propwash and it is not more aggressive, its simply need more throttle, thats why it makes a feeling that it is aggressive, but this is not true.

[@ondrascz1]

From the list of 7" props provided above the Fold F7 are by far the best ones. The best effectivity, the smoothest flight, the least amount of low frequency vibrations (and thus jello), no PW on the properly tuned craft.

[@Pukkaras]

@@ondrascz1 I flew more than two hundred batteries on different 7-inch propellers and had the opportunity to fully compare. I have feeling that we are talking about different propellers. Here, the effectiveness of dalprop fold simply for reasons of the laws of physics, cannot be the highest. Fold7 shitty shit, do not buy them , dalprop 7056 is one of the best, and gemfan flash may be the second

[@TheTryzna]

Not an expert, but had most success running dalprop folds on seven inch quad. Smooth AF. Had bad experience with HQ 7042, especialy with consitency of quality, some were ok, some were good, some just gave jello staight out of box.

[@ondrascz1]

@@Pukkaras Sorry for my total lack of competence, I flew only 597 pack (out of total 3893) with a several kinds of 7 inchers. I fly FPV 7th year now and 7" for 3 and half years...

[@waldemarkraus2855]

@@ondrascz1 I tested nearly every 7" prop on the market: -Fold F7 v2: least efficiency, but also least thrust. Good balancing and good response (7.5g), -HQ 7040 durable: best balancing, good efficiency, worst response due to weight (9.5g) -gemfan 7040: most efficient 3 blade prop, good response (7.8g), bad balancing -gemfan 7042: good balancing and efficiency, very flimsy, absolutely useless for heavy builds due to flutter -HQ 7045: good efficiency, bad balancing, very loud -APC 7x5: balancing ok, very stiff (no flutter), best efficiency for speed cruise, -gemfan cinelifter 7035: best balancing of all, leight weight (7.5g), very good efficiency. Since very new prop, need to do more testing

[@LeesEBR]

What ESC are/were you running with these motors?

[@FreeBirdFPV]

i got one set winding is disaster :D but cheap and working

[@motorbreath1415]

What if use 4s with 1300kv eco max 280&?

[@FPVUniversity]

Will be slightly underpowered. But it will fly

[@nickoo29]

what size of bearing

[@pav2k]

Not the cheapest? Aren't they cost only 15$?

[@TheOneAndOnlyRandy]

Do they even cost that much? I just put 8 1300kv on a Shendrones Thicc. Also have 1700k on 2 different 8 inch builds. They are awesom

[@Chris-vc1dh]

Pawel, what esc amp is enough for this motor 1700kv?

[@Pukkaras]

I am not pawel)) but, I will try to answer. Firstly it depends on what you want from drone (speed , cinematic or else), secondly on motor diameter, and third on weight of drone and props diameter. I use jhemcu 40a 4in1 with 7inch props and 2307 1750kv motors(drone weight is about 800-900g with camera and batt). I fly freestyle, and never pressed gas more than 30 amps. At 30 amps, I fly 100-120kph depending on propellers and weather. never reached 40a. I see no point in a more powerful controller. At 30amps I reached 50-60% of throttle .

[@wolfsblutinktattoos]

Can i use 6s too on the 1700kv Motors?

[@FPVUniversity]

with 7" props? Yes but you will have to be very careful with throttle.

[@wolfsblutinktattoos]

@@FPVUniversity What i have to Set in Betaflight?

[@StanislausCaps]

Вроде Павел, а говорит не по русски...)))

[@hanzalapatel703]

T-motor F90 is better

[@waldemarkraus2855]

Nope. They are very soft, using a 4mm shaft that bents easily. Best Motors in this class are Brotherhobby 2806.5, because massive 6mm shaft and 12mm bearing. I tested them all: Racerstar airA, T Motor F90, EMAX Eco 2807 and BH. BH ist the clear winner in any terms.

[@dnukPL]

@@waldemarkraus2855 Thanks for Your comment! I'm just trying to decide: emax or BH and figure out the real durability difference beetween avengers and Eco's II. Brand new Eco II will be always better than any old and used motor. So, the question is, are those Emaxes durable enough to consider them to buy, or Avengers are far more hard to break than Eco's? Paweł did test of them - i really appreciate this, but i think we shouldn't compare brand new motors to the used ones - Lets crash that Eco II several times and see how it performs after some time in the air ;)

[@waldemarkraus2855]

@@dnukPL I noticed that the ECOs had more imbalance than my other motors (airA, BH, T-Motor). Otherwise they seemed to be decent for it's price. Only downside, they weight 5g more than BH and T-Motor f90, but they also provide more stator volume and therefore little more thrust. They also seemed to be a bit less efficient.
