Default Trex 500 Scale Blades

Hey everyone, I have a scale project that I'm trying to complete. I never thought I would have trouble finding scale rotor blades for a 500 size heli. Anyone have a source or a suggestion? The only blades I can find online anywhere in the US is RCAerodyne, and they are the 470 size blade for the AS350. Would 4 of them work in my Align 500 4-blade rotor head? Any help will be greatly appreciated. Thanks!

Those are actually closer to 450 size. I use these on my 500s: CarbonHobby (BL-425-C-4B) EP 500 Class 425mm Carbon Fiber Main Blades for 4-Blade Main RotorFlybarless / Multi-blades.

Glad to help! I run these on my Little Bird and Apache, and they work quite well. Just be aware that they tend to prefer a bit more headspeed than the wider 3D Blades.

Both the spin and helitech blades are excellent, but but be aware that they are only for CW rotation. If you are converting to run CCW rotation, the only options Iíve found are the carbonhobby blades, and Hobbyking plastic blades.
