| as of now, we are thinking of getting astro flight's cobalt 40 direct drive motor to be used for our project coaxial rotor helicopter.
here is the link to the motor's specs:
http://www.astroflight.com/e/env/00...products:af-640
we have estimated our helicopter's weight to be at 4.86kg (maximum) including the cobalt 40 motor. we will be using two motors for the coaxial setup.
based on the 100w per kg to hover. The cobalt 40 motor is rated up to 660 watts.
other than the astro cobalt 40 direct drive motor, what other dc brushed motors can you suggest we choose from which can be a good candidate to carry our helis weight?
thanks! |
