Keen to know what systems you mod guys are running in your B4's. Wanted to upgrade from my current 17.5 set up and have a go at mod. I though may be this http://www.amainhobbies.com/product_...-Connector-85T Seems to fit the bill while still being very afordable. Any thoughts? Alternative suggestions welcome. I'm aware it depends on track conditions, but does anyone find 5000kv too overpowering for the B4? Cheers fellas
