Poor Performance: The increase in wheelbase helps in making those long jumps. The diffs are the stock ones in which CEN says are stronger this time around. Haven't broken any while street driving. I do not use the large heavy tires.... just Masher 2000s, Imex claw dogs and HPI Geolandar.

Scouser: The OS .18 TZ value over .18CVRX is about 7MPH top speed and guaranteed wheelies. I bought the CVRX for $95 and TZ for $139 at Tower Hobbies. The TZ just had a significant price reduction.
