My husband is a radio control nut. This part of our pawnshop is his territory. He can build or repair any radio contol toy you could ever want. Right now he is working on a AUTONOMOUS UNMANNED HELICOPTER. A Autonomous Unmanned Helicopter (UAV) is used for aerial photography, surveillance, inspection, agriculture and many other applications. He has decided to sell this one so he can make a bigger one. Engine is also available for this-it is a twin cylinder.
