SUPERSKIDS SUPER BLADES EZ

SuperBlades EZ excels at hovering and very slow speed stability and is designed to help beginners learn how to fly and encourage them to stay with the hobby. They are not designed for fast forward flight (FFF). SuperBlades XP is for intermediate and advanced pilots and excels at fast flight, yet remains stable at hover. EZ has lots of lift with stock motors and gears. XP has shallower pitch (less lift). It works with stock motors, gears and 2S LiPo  ONLY IF  the helicopter is light enough, but  flight times may be shorter. Normally we recommend using a 12T pinion with the stock motor, or a faster motor, or a 3S LiPo battery. 

Once you've learned to hover with SuperBlades EZ, flown some small, slow circles and practiced nose-in hovering, you may want faster forward speed but may not feel you're ready for the agility of the XP model. SuperBlades are made to be modified. On the bottom of the blades you'll see a 1mm wide line scored into the trailing edge and the tip, at 2mm from those edges. These lines can  be used as visual guides. EZ's will still be stable, but hands-off hovering may no longer be possible. In the video below, about 2.5mm was trimmed from the trailing edge and 6mm from the tips. How much you should trim depends on your specific heli and what kind of performance you want. If you're not comfortable trimming the trailing edge, just trim the tips.

SuperBlades™ are advanced performance blades for fixed pitch helicopters like the Esky

HoneyBee FP, HoneyBee FP V2, Walkera DF4 (HM004), Exceed Falcon 40 (V1 only), EF Sabre, Dynam Hughes 300 and Phoenix FP, Venom Night Ranger II, Twister FP and other similar helicopters.
