just to let you know , the carbon blades for the hummingbird are on sale for 10.00 (long version ONLY out of stock/discontinued of the "stock"size) i allready have two sets and the fit the falcon perfectly. just ordered another 2 sets last night. for 10 dollars they are awesome. but you will need a faster motor, or go to lipo batteries. less lift, faster head speed. stables out the heli somewhat decently due to added gyroscopic effect of headspeed.
