Product reviews for KBDD 5304 Main Blades Neon Orange for Blade Nano

These blades will withstand impacts better than the stock blades on the Nano S2\3 however that comes at the cost of weight which translates into flight time due to spinning mass.

If you're starting out I would suggest swapping the stock blades for these then putting the stock back once you stop crashing all the time.

~1.27g each vs the ~1g for the stock blades.
