Exotek Racing Flite 72T 17.5 13.5 Spec Center Spool Set Black For Xray XB4 #1795
This is an optional Exotek 72 Tooth XB4 Flite Center Spool Set. This light weight spool greatly reduces the rotating mass of your XB4 for that extra boost in 13.5t and 17.5t spec racing. The Exotek spool set weighs 18 grams with the spur gear and the included coated hard steel outdrive cups. Machined 72t pom spur gear is included and bolts on to the lightweight alloy spool.
