This is a pair of All Terrain reinforced 2.75 inch wide tracks for the LT2 Treaded Robot. These are the generation 4 design. They have 4 ply mesh reinforcement, molded rubber with no splice. Different lengths can be ordered.
The Spektrum AR620 air receiver is a full-range, 6-channel sport receiver with DSMX/DSM2 compatibility and a compact footprint that’s streamlined to fit in a wide range of models. Great for Robots too!
