I'm a young guy, so I'd plan for the future.
I'd take the 5K, and buy a bunch of quality servos and receivers. Never seems you have anough of those anyway. Then, I'd buy a bunch of composite materials for Drela designs. Like enough spar materials to build 3 or 4 more Bubble Dancers and Allegros (I have already build one of each). And then some composite materials to build a handfull of Supras.
Of course I'd also have to order a bunch of tailbooms from tailboom.com. Then, I'd be set for building for a number of years.
