Until recently I didn't have a new motor that listed gauss strength to test on my rotor master but my Exalt Gold 17.5 tested, to my surprise, right where Exalt said it would, 1786. The highest gauss rotors I have are almost all Hobbywing: 2 - 13.5 (HUS) G4R rotors, 1785 and 1787, 2 - torque rotors (JUS, which I picked up last year when the G4Rs came out), 1775, 1796, 3 - torque rotors (JUS, just came in over the weekend), 1801, 1807 and 1810). I'm going to re-test the rotors I've been using to see where they are, then play musical rotors to see where they end up (2whl, 4whl or stadium truck)
