Hello from a fellow Aviation/Robot/UAV enthusiast. Noticed you were a member of the DIY Drone forum and located in the central KY area. Would you be interested in taking the hobby to another level by getting an area Drone/Quad Copter group organized? Maybe some joint projects or mutual help. Who knows, could branch out into other things. If your interested, give me a shout at my main e-mail address: mthompson@uky.edu . I’ll get together a distribution list and contact information with the intent of an organization meeting somewhere here in the Lexington area by early Fall. Thanks for your time.
Mark T.
