I have 1258's and busted one only because Jeremy Kortz put me in a board serveral times, and it took that beating for a while as I tried to get away from him during a race as he lapped me it was all fun and games so in order to stay ahead I had to run the sweeper boards full blast at Hot Rods and just bank-bank-bank the corner till I got on the straight. It was fun but I knew my someting would be in bad shape, unfortunatly it was my servo. But I am sold as a Savox customer, Oh and love the humming to I know when my car is on when my pitman forgets to shut it off.
