flight height of your quadcopter…?

Contributions
Uday Girish Maradana

Great explanation on constraints of flight/range of modern quadcopters, propeller pitch to thrust dynamics, & motor to prop relation. I was about to answer the question but you beat me to it and answered very well, great job (also thank you for the link to that quad calculator, it’s much better then what I was previously using).

Obviously it can go higher than that

Obviously It can go higher than 50m Initially now I am planning to make it go more than 100 m and get stable flight but for that I need more control over it … Actually I and my team in clg were thinking to use neural networks after but its hard… First we will try to get stable flight then we will think about it…

Nice question bro… @ Steven Reubenstone
Now a days Quadcopter technology is so developed and now quads can reach heights of more than 1 km . DJI phantom Quadcopter ranges from 250 m to 1 Km based on different models they have.
Constraints :

  1. Weight
    2.Thrust- Weight Ratio
    3.Power Consumption
  2. Flight time
  3. Current and Power rating of the motors
    6.Temperature of the motors in flight time ( If the Power rating is not high then the motors start heating up some time if you put propellers of higher pitch then power consumption will be high and the motors can reach more than 75 degree C)

Similar Constraints;
If Propellers length is more ( like if it s pitch ratio is high better use less rpm motors)
If motors rpm is high ( Better choose propellers of less size).
If you want to choose the different propellers sizes for different motor rpms u can again raise a question I will provide complete information including the impact of pitch angle on thrust.
Otherwise if u want to calculate yourself you can kindly visit this website.
https://www.ecalc.ch/xcoptercalc.php?ecalc&lang=en
Again If you want to make it autonomous there are several constraints which will be added in this list.
