●Use for T-REX 550E Helicopter
●The 520 3G main blades are designed specifically for extreme 3D flying, featuring both high agility and excellent stability characteristics. The blades` have brand new airfoil design, coupled with new painted graphics. In addition, the blades rigidity have been increased for better anti-torsion characteristics during flight. The new airfoil design effectively minimizes turbulence at the blade tips, reducing blade noise and power loss.

●Shape: Symmetrical airfoil
●Length:520x48x6.5mm
●Thickness:12mm
●Shaft Diameter:4mm
●Weight:Approx 200g/set
