Feb 13, 2013 · What is eCalc anyway? It is a web-based program to take multirotor design data and calculate some valuable information about the design. It was written by Markus Mueller. eCalc is a powerful tool to answer questions like "will that motor work" or "what will my flight time be"? You can use it as a "what if tool" to design your multirotor.

Jan 28, 2023 · I have used the ecalc quite a lot for my projects and it has been much more accurate than expected. For example with Turnigy 3648-850kv and Aeronaut Cam Carbon props the static current is within couple of amps.

Feb 17, 2014 · ECalc tells you something about the performance for each type of flying. For a given motor and payload combination, eCalc estimates the "flight time," "mixed flight time," and "hover flight time." If you are an aggressive flier, you want to maximize your "flight time," if you are

Feb 25, 2014 · Usually on ECalc I used the custom function because I normally have the info for my components on hand, so it was a pretty easy matter of just inputting the data and getting a pretty reliable estimate of my possible motor and prop combinations, specifically amps and thrust.

Jan 19, 2024 · eCalc Version 7.30 is available with immediate effect with the following main updates: general: Motor Search bug for similar motor typ names corrected; propCalc: Motor thermal curve at max throttle to get an idea how fast the temperature propagetes in the motor. perfCalc: Take-off Distance calculation; setupCalc: Flight Mission for Long ...

Jun 3, 2018 · The Hyperion motor flight time is greater than that of the AXI motor, contrary to the eCalc results. The Hyperion motor has lower resistance and lower idle current, important at low current levels. The 11x7 prop also is more efficient at …

Feb 14, 2024 · Finally into ECalc, I entered 8S 5000, just any old 35-50C battery is fine as we're only wanting to pull 15C; normal charge, a CC Edge 100A ESCand a 20x10 prop. Then I set up a motor search in Ecalc for 900-1300g, Kv 200-800 rpm/V and power 1-99999W, sorted by Kv.

Sep 7, 2014 · eCalc Version 7.30 is available with immediate effect with the following main updates: general: Motor Search bug for similar motor typ names corrected propCalc: Motor thermal curve at max throttle to get an idea how fast the temperature propagetes in the motor.

Sep 7, 2014 · And eCalc is within 5% accuracy on the latter. But suspecting wrong KV value in cheap chinese motors is certainly a valid concern I think that either the stalled prop (more drag = lower RPM and higher current) theory is the explanation or …
