T-Rex 450 RC Helicopter Rotor Blade

thingiverse

The rotor blades designed for T-Rex 450 RC Helicopters ensure stability, lightness and better flight experience. These blades can be printed with or without supports to maintain rigidity or reduced weight respectively. Balancing isn't required and these blades offer more lift than stock blades. Furthermore, upon crashes the blades break away to reduce damage to other helicopter parts. During printing, a raft is not necessary, infill can vary between 0% and 15%, two shells are recommended, and helper discs should be positioned at the tips of the blades to avoid warping.
