eCalc - xcopterDesigner - maximize your drive
xcopterDesigner

The xcopterDesigner of eCalc.ch visualizes your copter design and helps to evaluate the bigges propeller for a full symetric frame. For best efficiency maximize the disc area and use the biggest propeller. However always respect the physical limitation of your actual frame regarding propeller-to-propeller and propeller-to-hub clearance.
The framesize is the diameter between opposite motor shafts (with even number of rotors).
