I am building a plane for aerial photography. I don't want to add the weight of landing gear, but I think it will be too big and awkword to try and hand launch. I think a bungee launch would work well, but I have never ever seen it done before so I have a few questions.

What kind of bungees do I need?
How do I attach the bungee to the plane?
How do I attach the bungee to the ground?
Do I need to do anything special when drawing back or launching?
Any other tips you can think of?
