Wow sweet combo. I don't know though I have come to love the 1406 motor I have. It has plenty of power for the tracks I race at on 2s and is outright balistc on 3s. Guess it depends on the driver but I find it harder to drive a 4wheel sc with too much power. My lap times are inconsistant. To each his own I guess the 1406 works so good on my setup and is lighter than my 550 motor so I'll stick with it for now.
