The drivetrain holds up pretty good, not a single problem yet with it :)
Although previously, i had the stock Drift Package chassis with only bearings and the Ti screw kit.....


I ran the uforce and a lehner XL5000 in this on the IB3800 packs in the pics..... the motor mount loosened up, causing a stripped spur gear - replaced the gear, and ran it again.... 3 minutes later, the same thing happened -lol-

Tried the same setup in the SSG, and no worries at all... but i did only run it for around 5 mins only...
