Hi ! I was running 10.5t the other week with my R1 and was doing some fantastic laps. Even some of the A main drivers was amaze however after a few rounds I totally ran out speed and punch, thought was some ESC issue. Checked and the gear diff was totally gone. I open up the diff cups and found the gears totally worned. I've ordered a few packs of the gear set. I find that gears are smaller compare to others eg. Sakura. Is the new pack will be tougher ?
