The BFlight210 quad is the lightest 5" prop quad I've ever built. It flies completely different than my heavier quads like the Purple 215. It is a balancing act to select parts that keep it light but don't sacrifice on too much power. You don't want to end up with the lightest quad ever but have no power to make it fly fast.
These are the parts I used on my BFight210 build:
