Thanks for the nice link.
I was good with home made kits as a kid, may be this is a nice experiment as well. I am sure my wife is gonna love it if I loose a few camera and tools as she desperately needs more room at home.
I am looking at commercial potential here for example those several million dollar houses that are going to be put listed for sale and need aerial picture at a rather high cost. Only if you get the right wind every time
