I've seen tests were the other pulley is installed on voyager (higher top speed) barely looses any acceleration and gets closer to 40mph. I think the lingyi ESC adds more amps as the load increases.. the motors on the voyager are beasttt.. and the esc.. meepo doesn't mess around and knows the power of AMPS... You should do this test in your video, leave the hurricane as is and race with both pulleys , same wheels!
