Upgraded Dual Pickup Traxxas Spartan.This is an effective way to add a second water pickup to your Traxxas Spartan. Now you can run separate water lines to both the ESC and motor, resulting in better cooling. There are a lot of different ways to add a second water pickup to your boat, but all of them will add drag. That's why we developed our dual water pickup rudder blade. The dual water pickup rudder is a direct replacement for the stock rudder assembly, so we are not adding any extra parts to slow down your boat and reduce performance. A wider blade will help with lower-speed handling. Includes: Blue or Silver Rudder Assembly (everything in picture) Requires: OSE 7/32 water cooling line. Anything thicker will not fit the fittings. Specs: Color: Anodized Blue or Silver Aluminum Material: AluminumBlade measures 100mm from top to bottom. Mounting bracket: 20 mm wide x 25 mm high.
