Leadfinger Racing have introduced the new A2.1 Tactic body for the HB Racing D819 and E819. The A2.1 Tactic body is a one off design that delivers a tuning option in between the original LFR Assassin, designed for low grip surfaces and A2 Tactic bodies, designed for super high bite surfaces. The idea for the A2.1 body was spawned by Doug and Justin Fales when they were looking to gain more stability and slightly more down force to the existing A2 Tactic. The A2.1 Tactic body features cowl scoops on the side pods. Depending on the performance your looking for, these can be left alone to add to the overall down force of the car, or you can choose to drill them out for additional cooling. When opened up, the pipe side of the cowl pulls air directly past the block and manifold of the nitro motor. The A2.1 Tactic body sports also a fin on top of the roof. The advantage is more stability in high speed sections of the track and a more precise feel under hard cornering. The body features also an additional down force on both side pods and rear swoop. The new A2.1 body is available both in light weight or standard thickness and it comes in clear, including window masks, stickers and a front wing.
