Micro air vehicle has attracted significant attention on its potential application. This report studies the possible combination of selected available commercial batteries, propellers, motor, transmitter, receiver and electronic speed controller to provide maximum lift force under present restriction of micro air vehicle requirement. The possible combinations are suggested. All systems of unmanned aerial vehicle with strict limitation of weight and size must accomplish the mission in the conditions of low noise, long-range flight, and fast response. The requirement for accuracy is pretty restricted. This study explores the combination fulfilling the requirement, and utilizes power supply and micro components of transmit system available in the market to carry out optimal combination. We planned to select battery, motor, propeller, transmitter, receiver, and electrical transmission to carry out optimal combination to be used as power supply system of MAV (Micro Air Vehicle).
