Pros / Cons Multicopter PROS Good in rugged terrain, where a fixed-wing would be difficult to operate. Landing a fixed-wing = DAMAGE. Auto-takeoff and landings. Very stable in hover. Optimal for small site mapping. CONS Short flight times. More expensive than fixed-wing. More complicated. Parts failure can be catastrophic.
My Project - Maps The use of Drones for High Accuracy Photogrammetric Mapping: Orthorecified images DEMs (Digital Elevation Models) 3d Models Fixed Wing: Small area mapping Typical 1-10 km2 (5-30cm GSD). Multirotor: Site specific Ideas to Explore: Brushless Gimbal Systems (Alexmos) – worth the trouble? Optimal Camera + Fixed Lens
