The perfect addition to your small electric helicopter. Radix blades have an efficient, high lift symmetrical airfoil that gets maximum performance out of your helicopter as well as making auto rotations easier.
Their structural design results in a very controllable blade that is also quiet in aggressive flight. These 325mm main blades are perfect for T-rex 450 or other similar size helis. (315mm bolt hole to tip). Great overall 3D blade that flies quick and stable.
