Blue Eagle LS: released in 1991 the Blue Eagle LS (Long Suspension) was an evolution that resulted in a nearly all new race truck. It sported a new .25in. longer graphite chassis with 30 degree kickup, longer suspension arms and accompanying components front and rear, Pro-Series caster blocks and shortened axles at all four corners, shallower cone dish wheels with spike rear and ribbed front tires, and a low-profile racing body by A&L mfg. The transmission, bulkheads, steering bellcranks, bearings, etc. would remain unchanged. Only available as an unassembled kit, less electronics.
TRX-1: Introduced in 1991 the TRX-1 was an all-new pro-level race buggy. Abandoning the premise of upgrading an entry-level car to race spec Traxxas poured all the race parts into a single model. The chassis was a new .375in. longer graphite pan with 30 degree kickup, longer arms, shocks, and hardware widened the car by .5in., bellcrank steering and new bulkheads were added along with new graphite shock towers and a new externally adjustable three gear Pro-Series transmission. The unassembled kit contained pin rear and ribbed front tires on revised 2.1 wheels, full bearings and a new aerodynamic lexan body, less electronics.
