Calculating hovering of an electro plane

  1. Apr 27, 2015 #1
    I am trying to calculate the necessary amount of power (watts) for a RC plane to hover or to move vertically up. The electro engine has an efficiency of 80% and the propeller efficiency is 50%. The plane weight is around 1 kg.

    I have calculatet that i need 9.8W and with 50% and 80% efficiency I get around 25W. In real life this types of planes needs around 200w.
    So what am i missing?
