- Quotes and other details: I just picked up my Sport after trading my Defender/Tactical for another crawl/trail truck. Swapped out electronics to Holmes Hobbies 1700kV sensored motor with Mamba X ESC and a stronger servo (with metal horn). Also put on some metal beadlocks I had from another crawler. Truck is great on 3s with 15t pinion and stock spur. The weight loss is so apparent (compared to Defender); this truck is fantastic so far! Can't wait to add a few other pieces here and there, but so far so good. Well done Traxxas! I basically never used my 2 speed or the remote diffs so it wasn't needed for me.
