How to select the right motor for your multi-rotor (all types - Tri, Quad, Hex etc.)

This is a short video to show the results of my lessons building quad-copters to help answer those subscribers who have asked questions around this topic. In this video I explain how to size the motor and what ratios to use to get the right power in your model from my experience. Basically - you need to have a little over twice the weight of the model as thrust from the motors to have the model comfortably hover at the 50% point.
