I am braking a lot of stuff on my Losi XXXS, even though I do drive stock motors, and am not a big hitter. When checking the Graphite parts that brake I found out that it has a lot of air bubbles in it that extremely reduces the strength. I'll contact the Dutch importer on this. The things that brake, brake in a starnge way. Not a normal clean brake.
By the way, even with only one qualifyer the car took me to 7th in the B final, with over 50 drivers in totalk and the Dutch top racers at the start. Not to bad!
