Based on the fact that a fully charged P3 battery will give you 20-23 minutes of flight. How many flights can/should a P3 owner expect his drone to last before it has mechanical failure? What on a P3 will have the shortest life expectancy; what can be expected to wear out first; the motors, the batteries, the esc's, the main board, the camera, etc? P3's have been out now for what, 3 or 4 months now? I doubt anyone has worn one out this soon yet. If one did wear one out, can they be rebuilt at a reasonable cost?
