0evildoctorbluetooth 11 years ago UAVs such as Herti are built to fly either with programmed instructions or via remote control. a large portion of the systems are automated. now if you want to make one, i would presume you would have to first build the plane, any way you like, remember its remote control, you can find plenty of advice about building RC planes on the net, including how to power it. now when you say unmanned, im going to assume at this point, that you want the commputer to control it, without you at the controlls, for this, you would need to somehow connect the computer to the remote control to the computer. as for the rest im afraid i cant help you.
