I am in search for a new drone. I need a powerful drone which can tow a payload of 3.8 kg. It is for a research purpose. I have ordered an airbird for geological survey. I want the quadcopter to be able to tow it and it should have a good range and flight time. This is what I would want. http://www.gemsys.ca/uav-magnetometers/ This is how I will be flying the instrument. So, which drone would you suggest for carrying a heavy load? Please share your thoughts. Thanks for your time.
