Bought 1st month out in Dec 2015,got two years running hard on it,have updated gears, drive shafts, center diff added this winter.still run 1600kv motor.plan on staying 6s now that I have upgraded drive train. also run stock aluminum diff housing an aluminum covers,tie bar supports.kershaw design tires are the best, change handling to the good,can keep wheels on ground, handle like slash 4x4. Way better tires for the drive train , cause they break lose easier,helps keep front end down to ecelerate faster.trying center diff with cush drive next year.my talion is for higher speedy stuff.
