Off season FRC quadrocopter build

[ferret_guy]

Thanks all the input the biggest concern I have is safety, I am aware that it can be done easier but I wanted to do it with frc parts. The only problem with it is the props, is that the prices make me sad . My idea was to simply fly it very low after performing extensive static testing and whatnot. However by changing the props as EricH suggested the result was unable to lift off, could you provide more info on this?
