These tools may further support you by calculating RC-related tasks:

  • cgCalc: Calculate, evaluate or verify the Center of Gravity (CG), Neutral Point (NP) and Aerodynamic Center (AC) of your airplan before maiden. The only CG Calculator for upto 5 wing panels.
  • control surface moment: calculate the required torque of your servo.
  • decalage: evaluation with some easy measurments on the table.
  • TRUE C Rating: calculate the true perfomance of your battery.
  •  wingDesigner4: evaluate and vizualize the center of gravity (CG) of complex wing
  • wingDesigner: evaluate and vizualize the center of gravity (CG) of your wing
  • xcopterDesigner: optimise and visualises your copter design.
