What's the relationship between thrust and torque? I have noticed two methods to measure motor thrust and other parameters. One the motor is mounted vertically and second, it is mounted horizontally to an arm. The second method makes sense as in torque = force * radius, the force can be measured using a kitchen scale or something similar and radius is the length of the arm. But the first method there is no arm so how do you work out torque? Baffling!
Ok, I don't speak English very well and the translator can confuse, to know the necessary thrust, the weight is total? Fuselage, thruster train, and payload, so I look for the combination of thruster train that meets the requirements, say at 50% throttle?
There are formulas, but they are functions of many, many variables (6 or 7 +). For this reason, I like to stick to the empirical data. You can check out this guide though if you're curious quadcopterproject.wordpress.com/static-thrust-calculation/
I normally don't manually calculate the thrust of the motor/prop/battery combo. A good motor manufacturer will post thrust tables that documents the empirical data of the thrust performance, then you can engineer your build off of that data. A good example of thrust tables can be seen at the end of this page for an EMAX motor emaxmodel.com/emax-rs2205-racespec-motor.html However, if you wanted to calculate thrust, you could probably do this with a scale and an upside down prop (so that when it spins it presses the motor down).

Heyy guys , I couldn’t find the next video after this . I am desperately looking forward to watch that video.

Hello how can i estimate the thrust is there a formula?
Could you please tell me about the mechanical testing performed on drone frame

thank you for this.

It is total weight. You can adjust the TWR by choice of battery. But a lighter battery means shorter flight time.
How to calculate thrust, any formula?

Thanks sir
5:00 a drone with TWR===1 could probably NOT hover at all, but would sit on the ground, and be unable to lift at all!!!
You are just making it more difficult. Go check out Painless 360's video on this topic
Flying car
I very much doubt that these toys could hover with TWR
I think you'd be surprised! It is a bit counter-intuitive to see how well the drones can fly with TWR around 1.5
@@thedronedojo Q: How do you [mechanically] measure drone's Thrust?? I don't mean with formulas; I suspect you are using an incorrect method !!!
@@kareemsalessi Please see here www.droneomega.com/drone-motor-essentials/
@@thedronedojo Thanks. That's pretty extensive. Do you know with which device/s they measure a motor's thrust-force ??
