I am running a cheap Amazon combo. A knockoff of surpass hobbies system. It's a King Val 35A ESC and 2435 6100kv motor. Way better than the 2 in 1 Dynamite or spektrum imo. I'm running Urgenex 1100 35C 2s lipos. Good cheap and reliable packs for 22 bucks. Running RadioLink RX/TX and a savox servo.
Losi Minis. (B, T 2.0, Jrx2)
