Racerstar 2500KV motor thrust test | 1000 Kv motor thrust test | DIY Test rig

This video is all about the thrust test of Racerstar 2207 BR2207S Fire Edition 2500KV. I have tested this motor with 5-inch and 6-inch tri-blade propellers. I have also tested a 1000kv brushless motor with a 10-inch and an 8-inch propeller.
I have also designed and made a Test rig. The best part of it is that we can test different motors on it.
Watch this informative video, especially the conclusion part.
There's so much to understand in this video.
Thank you and have a nice day.

[@ecbmanikandan]

I Have one Very Simple Question, Why Table Fans Propellor not Creating Much Thrust Like Other 2 blade Propellors.? Is it Because of Rpm or Propellor Design Machi..!

[@MechNinja]

Both the things. Their propellers are meant to be designed in such a way that they will only push the little amount of air to provide the comfort and also their rpm is low.

Can I use a 920 kv brushless motor and put gears on it so that I can increase the speed of the propeller, is it similar to the system used by (commercial) toy drones?

good one. why don't you make a video of all the motors with different KV and different pitch propellers and share the test results? it would be so informative to all.

I will definitely share it bro but along with the passage of time.

1000 kv motor and 6045 tri blade props how much thrust ?

[@loodwich]

I can use the Racerstar BR2205 with 6inch propellers, but because my normal pressure is only 790hPa. Also with a 4S battery.

[@MechNinja]

If it's recommended to use a 6 Inch propeller than its better, but if not then the motor will draw much current and time of flight will be less. But If your requirements suits the 6 Inch prop then go for it.

[@jaypatel6801]

These small motors draw much more current than an normal induction 3phase motor according to their size

[@saraheart8527]

Because of the low voltage, they would naturally have to have a high Amp rating to get much Force/Thrust

[@leohale9550]

hey im going to use a 2500kv and 40 esc for a plane and was wondering what is the c rating for the Lipo battery?

[@saraheart8527]

You are supposed to know that by the manufacturer's specs. And every battery made has it's own C rating depending on the quality of the materials used, as well as the quality of the build by the battery company. These companies are notorious for over-rating the crap out of the battery's to impress you and get you to buy them.

[@MechNinja]

The C rating are mentioned on the battery itself.... And thankyou for watching the video and don't forget to subscribe 😊😊😊😊

[@merxellus1456]

Bro a question.. could a motor fly a plane whos total airplane weighs greater then the trust produce? Example a motor with trust 500 gram flies an rc plane with 600grams? I like to know the minimum thrust required to fly an airplane in Trust to weight ratio..

[@MechNinja]

Yes definitely it can fly......as the thrust is produced by wings...and the motor helps in speeding the plane. Make sure you do not fly in vertical position.....or it will come down....😊😊😊 Don't forget to subscribe....😊😊😊

What application are you going to use these on? Also, have you tried any other propeller designs?

[@MechNinja]

Well it was a test for my new and old motors. Because I want to compare the actual thrust of the motor with its performance chart. And I need the results because my future projects are complicated and so compact that these parameters will play an important role in designing that. So I shared the results with you all. And yes I have used different propellers because racerstar 2500 kv motor was designed for 5 Inch propeller but I have tested it with 6 Inch too. And 1000 kv motor for 10 Inch but I have tested it with 8 Inch....and I don't fee like to use more propellers on it because these sets were common. So hope you liked my video...so thanks for watching and don't forget to subscribe... More cool stuff is coming on the way...☺️☺️

[@tobins6800]

@@MechNinja you're obviously an engineer. What's commercially available isn't always the most efficient. You also have a 3d printer, and that was also the short way of asking if you had access to research and knowledge that the basic public doesn't have, or, have aggregated said knowledge from the multitudes of sources out there. For instance, the noctua fans have an extremely efficient way of moving air around and are some of the quietest designs. I do wonder how long it will take to get aluminum and iron based batteries for things like this. What has been promised for performance will be exciting for projects like this.

Can i get some information about readytosky 920kv motor How much weight can carry this motor

[@MechNinja]

Well I have not used that motor...but according to its kV rating...it might give you around 900 gm + thrust. But i am not sure...you need to check it's thrust chart

[@vividprimevision]

*Bro but the time is important.Can you test fpv motors 2 blade vs 3 blade vs 4 blade vs 5 blade?*

[@MechNinja]

The motors I have tested are fpv motors or racing drones motor.

[@arshikhan6259]

How did you come up with the ideal thrust as 95 grams?

[@MechNinja]

Ideal thrust is the dead weight of the arm to lift it to the height till the arm reach the horizontal position. I have calculated using the spring balance. Don't forget to subscribe 😊😊😊😊

[@abipaily228]

1000 kv , 6045 tri blade how much trhust ?

[@MechNinja]

6 Inch propeller is not suited for the 1000 kv motor because it has low rpm and high torque. 6 Inch propeller need high rpm motor so I have used a 2500 kv for it. Hence there's no use for using 1000 kv with 6045 Hope you got my point. And thanks for watching and don't forget to subscribe 😊😊😊😊

[@ashiknabil4106]

Bro which is best motor to produce 25kg of thrust ?

[@MechNinja]

25 kg thrust is way more for electric ducted fan (EDF). The max thrust which a commerical available EDF can produce is 12 to 13 kg max. So you need to use two of them. But the problem will be the battery size because these EDF consume much current. And also if there is no such requirement.of EDF than you can go for T motors. T motors has a lot of thrusts. It can easily provide you 25 kg with 24 Inch propeller but it is costly. And if you are planning to design a manned drone that I will suggest you to first make its miniature version and find you the problems. Hope you get it and if you'll face any problem then do comment.

[@aju5405]

In the video you showed 2207 motor, 2212 motor.both have around 600g thrust. Then what is the difference between these two? I heard that 1045 propeller is used in heavier plane models

[@saraheart8527]

1) you are fighting gravity with this method, and 2)changing the angle of the force. I don't believe this will be a very accurate test.

[@MechNinja]

Every drone is fighting gravity...so do we.....

[@MechNinja]

I took the reading at the time when the motor is horizontal....and I think, that is the ideal case when we need to calculate the thrust.....

[@ed-7]

If he had an adjustable weight opposite the pivot point, to counterbalance the motor/prop combo until the ensemble was resting horizontally, just as the string became taught, the result would be more accurate.

[@MechNinja]

Since I am calculating the ideal thrust and adding it in the final result, so the counter balance method is eliminated..... But in my upcoming videos i am using more accurate rig to test the thrust. Thankyou for watching the video and don't forget to subscribe 😊😊😊

[@saraheart8527]

@@MechNinja True, but I am calculating for a fixed wing, Besides that, all manufacturers do not calculate thrust agaist gravity, they are calculating the total horizontal thrust, THAT is the standard.
