I saw the Losi's for the first time at Phatdads and I was really impressed with them, they're way bigger than the Baja. As to the OP, I would put money on the Baja beating the 5ive-T in a hill climb, especially in sand. Baja is lighter and the 4WD will bog the Losi down, too much rotating mass. Power to weight is the key and the Baja takes that.
