In this video we'll take a look at the Emax GT3520 / 05 brushless motor and get an idea of its thrust output and amp draw. I did not have a 5S (5 cell) battery to test with, but it does seem that the thrust output would be significantly higher than the 3000g that is advertised for the 5S 11x5.5 prop setup. Also, I know that the 13x5.5 propeller is larger than recommended, but I wanted to see what would happen. Interestingly, with 4S and 12x6 prop on my setup, I'm getting thrust measurements ~500g higher than advertised.
⚠️ UPDATE 12-20-20: Unfortunately, the GT3520/05 appears to have been discontinued. If you can find a source for it, let us know in the comments!
What do you think of this thrust test setup? This is the first motor I've tested, so I'm wondering if there are any issues with the physics/geometry that I'm not aware of that would cause my numbers to be inaccurate (like, off by 50grams).
Thanks to Banggood for providing this motor for testing.

Great video. Thank you for gradually increasing the power, instead of going from 0-to-max instantly. Your method allowed me to actually do a thrust vs. power graph. :)
Thank you so much for this! I’m pulling thrust data from your screenshots for a research project. You saved me tons of time.
I like this motor
Thanks for the test data, just ordered one and was wanting to see how they run on a 3 cell lipo.
Would have loved to see 4s with the 1355 prop.
Love the big motors! On some of my larger builds I like to test all of motors. The Turnigy V3 thrust stand works great.
Hello, please provide an analysis of the brushless motor gt 3526/05
nice work
How did you drill holes in propeller. Kindly make a video. Any balancing problems???
I have one question about what is
A 3 phase brushless motor has the following values. The maximum current drawn from the battery is 4.62 amps.. The thrust is 4025 grams with a three-bladed fan 18 * 8.. The speed at the maximum lifting force is 2780 rpm. The battery voltage is 23.46 volts. How much is the output power? How much is the efficiency?
friend which model would be more economical the 5010 or the 5208? and which is the most economical of all you know?
GREAT MOTOR, 👍
Looks like a good one im using a couple turnigy aerodrive 4240 740kv . but i do like the numbers on that one mabye have to try a couple . 👍🎲
Thank You. I want to buy that motor!
Yes yes i need it now
You make your video very good i love your all video
nice video
Great video! I am a bit of a beginner but want to build my own thrust testing rig and I was wondering why the pivoting arm is used instead of just attaching the motor to the top of the scale, perhaps for stability? Also, this may be obvious, but I was just wondering if you put the propellers on the motor upside down so the force is directed downward at the scale.

may i ask? is it okay if i used a 8x6x3 propeller to this motor?
Dear Sir,
If the thrust of motor is tested horizontally. Would thrust be the same when we use it for vertical flying?
An Rc plane engine states that it has static thrust of 23.5kg at 1800 meters. Does that mean straight upward from ground?
The question what I'm trying to ask is: if the thrust is calculated horizontally, would it be same straight up vertically?
Hi! Good question! Yes, the thrust would be basically the same both horizontally and vertically (of course, other factors like propeller type, air density, airframe drag and battery type would make a difference). I'm not sure about the "1800 meters" specification, Is that for a brushless motor or a gas/nitro engine?
Sir, I want to calculate the power of a brushless motor. I have the values of lift force, speed, current and voltage of the battery
What would be the recommended frame like a Tarot IRON MAN 650 Folding Carbon Fiber Quadcopter Frame???
nice motor
Witch bettery should I use with emax 3520/05 tell me please
Your 4s battery is a bit weak, droping from 16.6 to 14.0 when you go full throttle. You should get a battery with a higher discharge rateXcapacity (C times mAh)
Why doesn't tare weight go back to 0 when prop stops as it was 0 at the start? 7:22
Very interesting ... I am a newbie and maybe everything I say here may not make sense ... it seems to me that the motor is turning to the right (cw) when you look from above ... and the propeller (see in 4:19 ) is like a spoon ... therefore the propeller pushes against the balance (OK) ... if for some reason the direction of the motor changes (ccw) ... that arm holding the motor will swing on the pivot ... A highly dangerous situation. You must put some restriction that prevents something like this from happening.
Question...If you design the contraption for a tractor motor combination ... will it be more efficient? ... so this motor and propeller combination ... will produce more thrust? Thanks!!!
Hi. You are correct in that there is nothing to physically block the motor from pivoting the arm upwards. However, the motor is wired to only spin one direction, and it cannot be unless two ESC wires are swapped. So, that is why I had the propeller upside down in a "pusher" configuration. Did that make sense?
@@RCwithAdam1 Yep!!! ....If you are the only one touching that contraption...no problem. If you have a brother/sister that like to prank...then...put a strap to that arm. Better safe than sorry. Good Job!!
Does that propeller locks itself into same position when the motor stops?
No. It's random.
What is the esc that sutiable for this motor
My friend good vídeo but i have a problem i don’t found This motor
Please share the purchageing motor link
very good video, excuse a query to these engines you can put 17-inch propellers
Where can you buy 1 of these??
Hey, do you have the values from 25% 50% 75% and 100% over Current, Power and Thrust? thanks.
Hi! I don't, sorry!
@@RCwithAdam1 dont worry. but maybe you can help me.. I need 1400gr of throttle for my plane, if I see a motor that provide me 1500gr at 50%, this means that I do not need to push until 100% or 80% the throttle, right? only with 50% I can keep the plane flying, right?
@@RCwithAdam1 have you ever done thos test with ducts to see if they have a measurable effect?
I need that motor where can i get that motor
Hello " intrusted this moter " i like this moter " i did chek but available this moter for perches " so i request you please sir " where from can get this moter
Which esc did you use with this motor sir
80A 5.5vBEC 3S-6S Brushless ESC sold by ZTW
Where do you get the propellers from?
I think I bought these at the Joe Nall event.
Gt 2215/09 can take 4s????
Esc will also come if we will buy that motor
Hi! No, I purchased the esc separately.
Hey there, I think you might want to consider adjusting your thrust test jig in such a manner that the motor isn't that close to the desk because I think you'll get a lot of ground effect from the nearby desk surface with this setup which will skew the test results.
Good point!

Is it safe to run it at these speeds?
Yes.
a cople of decant little motors i am sure u could bit a lite plane with a wig wing span and i rekon these could take some1 off the groud
where can i find this now?
I think it's been discontinued. 🙁
The difference in power from 3s to 4s is very big.
I'm from India
Hello bro give me this link to buy plz there is no motor according to the link
Hey! Unfortunately it looks like emax discontinued this motor. 🙁
Can we use it on 6S??
No. At least I wouldn't try it.
i think these wires arent rated for 60 amps
Tell me sir please what price for Indian inr price
Rs 3500
How do you get the data from the kitchen scale into the amount of thrust?
The scale measures the amount of force from the thrust of the propeller (the prop is mount upside down), which gives an approximate measure of thrust.
Please i need that motor
where is 4s and 13x5.5?? i have 4 s and 13x8
I neen it now
I would if just sent it..... on 6s...
Full power 🤣🤣🤣
Hi dear, this is Rebecca from Snaptain, i would love to invite you to test Snaptain new-released drone, are you interested? If, pls let me know.
Get 4... 😀
And sir about bettery
run on 30 amp esc
I'm a student sir

Gt 3520/05 motor kv
🤭🤭🤭😂😂😂🤩🤩
MONIR
Haw mach price in us dollars
About $35.
😱😱😱😱😱😅😅😅
Tell me please
You need to include actual motor Kv, RPM in each test and voltage across them. otherwise the test is useless. Airplanes fly by propeller speed. not by push.
Hi. You're right, more data would have been better. However, total thrust output is still a very useful measurement regardless of rpm.
@@RCwithAdam1 how many thrust is necesary for fly a sailplane? haw many for speed is necesary?
The effy in a motor is Watts In vs Watts Out= Work. Work is Thrust + proppeler speed. where thrust is inversely proportional to speed. at higher speed, less thrust at the same power.where thrust is inversely proportional to speed.
where prop speed is RPM *pitch/1050=MPH
