computation on weight capability
given the specs of a motor (spec sheet of an astro flight motor) is there a way on how to mathematically compute the weight that it can lift for a coaxial design helicopter setup (or a single rotor)?
thanks!
thanks!

It'll depend on the gearing and the design of the rotors... you can get some good approximations from the specs of some of the electric heli models that are already being made... but you change the gear ratio 10%, the motor speed changes enough that the load capability can be WAY different. Adding one cell to a 7 cell setup. you added weight and gained even more weight carrying capacity, but reduced flying time at full throttle...
Just too many trade-offs to make a calculation for it based soley on the motor size
