I picked up another $1.99 piece of balsa wood at Hobby Lobby (the craft store - sadly there is no local hobby shop for me) and threw this together last night. It had balsa legs for about 10 seconds but they snapped off.
These zip tie legs are more durable and provide shock absorption. The quad in my above post had an all up weight of 205 grams - this one is 175. The difference in weight is noticeable in vertical ascent and I gained about 45 seconds of flight time. A word of caution to anyone who wants to try this - it is far from crash proof. It it falls from the sky it will snap in half, but the electronics won't absorb as much of the impact, and the frame can be repaired or replaced at little expense.
