I have an ECX Ruckus With full metal transmission metal spur gear and a 4000kv brushless Onyx motor. I have some metal hex's coming in because my plastic ones melted. Its heavily modded and almost indestructible under its own power. The only problem is my Pinon gear is striped and I need help figuring out what to get because this one was no good. I need to find help on what Brand, Teeth, and material to get SOOOO Please help me out so I can continue bashing.
