Estimate DC Motor & Prop Combo
Check out the GUIDELINES to help you choose your Plane's Power System  -  Last updated: May, 6 - 2024
Disclaimer: The calculated values are only approximate.
The calculations are based on assumptions of Battery, ESC & Prop performances, which may deviate from the real.
The accuracy is usually about ±12%. However, it is strongly recommended to measure the actual max values before flight.
We do our best to provide the highest possible accuracy, but if you spot bugs, significant discrepancies or have suggestions,

Calculate Wing Loading & Stall Speed :
 Wing Area
  in2      dm2 		 Wingspan
  in     dm 		 All Up Weight
  oz     g 		        Wing Max CL
          CL
RESULTS:
 Wing Loading
  oz/ft2   g/dm2 		Cubic Loading       Thrust / Weight
oz/ft3      /1 		 Power / Weight
  W/Kg   W/lb 		 Stall Speed
  mph  Kmh 		  Aspect Ratio
  
Remarks (if any):


Airspeed [Km/h]

      Estimated max level flight airspeed:
       mph          Km/h 		CDoL
Disclaimer: The calculated values are only approximate.
You may change the value of CDoL to change the Zero-Lift Drag Curve.
The calculator can be useful for comparing different Propellers.
