Thunder Power Z3R-S Stock Spec 540 Sensored Brushless Motor (13.5T)
Bought this motor from my buddy Dave Merry and watched him tune it on a dyno for me. This thing puts out some power now and runs really cool! I have it in my 13.5 latemodel paired with a Hobbywing Justock esc, i replaced the esc wire with 12awg and i do run a WTF fan and integy heat sink to keep it nice and happy. After a 40 lap dirt oval race of basically fun throttle action it comes off barely warm to the touch. I am very happy with this motor performance and really want to get a mod motor to see how it will perform also!)

Thunder Power Z3R-S Stock Spec 540 Sensored Brushless Motor (13.5T)
This motor Burned up on me the very first race with it in my Kyosho RB6. Run it on my viper V10R ESC got it little hot one time durning a club race and it was done! Thing is my dad runs the exact same setup RB6 with the exact same gearing and ESC and everything except with a Shuur speed 13.5 motor and that motor stays cool and runs awesome. This Thunder Power was 100 bucks up in smoke...)

Thunder Power Z3R-S Stock Spec 540 Sensored Brushless Motor (13.5T)
I have raced this motor a few times now and every time it just blows my mind how quick it is, I havent even maxed out the timing yet so it still has a bit more performance left in it to go. I actually bought it based on how cool it looks but the looks match the performance and then some. This is a quality american built motor you wont be disapointed . A couple of the other features I like about the motor is it is shorter and lighter than other brands like LRP speed passion etc. My favourate feature is the way communication fits into the motor)
