SAB Thunderbolt Blades were designed to grow the performance of your helicopter. The amazing design was developed not only for an asthetic purpose, but it also improved the visibility of the tip of rotor, higher visibility is necessary in very low maneuvers. The variable profile along the radius of the rotor makes the "SAB Thunderbolt Blades" 20% more efficient in comparison to the SAB Blackline Blades and gives great stability to the whole helicopter without compromising the agility of the rotor. The chord varies along the radius of rotor (Shorter at the root, larger at tip); thanks to the aerodynamic of the rotor, gives more thrust exactly where the rotor generates it, that allows harder and more precise maneuvers in flight. To improve the stiffness the "Thunderbolt Blades" includes double layer of unidirectional carbon fiber. In order to guaranty safety in the event of a crash, we include a steel safety wire alongside the leading edge of the blade.

SAB Goblin 420mm Thunderbolt Carbon Fiber Main Blade Set
Mine are junk. 5.2mm thick at the root and won't fit the SAB 420 grips, hazy areas in the finish and heavy. Didn't bother returning them but carefully sanded down the bottom root area small amounts at a time measuring with a digital caliper. Ended up with Alzrc blades. They weighed good / equal (8 grams less than SABs each), COG good and perfect on the balancer. The Alzrc had better lift and agility. Flat out the SABs are to heavy and flew like crap.

I will have to second what the first reviewer said. I have had to return two sets of the SAB 420 blades because they are most definitely complete crap. Oh well, lesson learned..
