### ⭐⭐⭐⭐⭐ Powerful
*by R***A on April 22, 2025*

Great for 7th scale

### ⭐⭐⭐⭐ Unnecessary power button!
*by A***L on April 6, 2025*

Comes with a power button that will need cut out of the harness and wires soldered back together and heat shrink applied. This should be an option like the adapters for JST to 2s or 3s balance leads.
