Profile Information

About Me:
I am a licensed home Inspector in Illinois with experience as a private pilot. I also have a limited amount of experience building model RC planes and assembling electronics on PCBs.
Please tell us a bit about your UAV interest
I am looking to build a task-specific drone that is designed to do inspections of roofs without the need for ladders and actually walking the roof. I am looking for the optimum flight controls and camera sensor / lens that will make roof inspections safe and result in quality photographs that will be included in my inspection reports. Video capture is not a priority, and speed and distance traveled is also not part of my criteria.
