Hi everyone, I am new to this and I was nocked by a rock wall. My goals in this drone are for it to hover and to have a flight time of 25-30 minutes. I have estimated total weight of 1300 g, taking into consideration all of the components.
I found a rule of thumb that recommends multiplying the drone’s total weight by 2 and adding 20% more margin of error. 1.3*2.2= 2.86 Kg. this ends up with a total of 715 Kg of thrust per motor. Now the voltage was calculated by multiplying the thrust times 3. My final numbers were Thrust=715 Kg, Voltage=2145 Kv.
I was thinking of buying a 4 in 1 ESC with 45 Amps. I think a 45 A is somewhat bigger than what I need, but is there anything wrong with a bigger ESC?
The largest propeller that my design allows is 9 inches long, meaning 9045 propellers.
Please feel free to drop any recommendations. Everything helps.
