i just finished building my m18 then, when i tested it theres this clicking noise(souds like gears slipping)esp. when i gun it????anyone experienced this problem????
That seems to be a very common problem with the Xray. I just run it till it breaks. It seems like the stock gear diffs just aren't strong enough for a mod motor. The ball diff will be out soon they say and it will solve that problem for sure. In the meantime there was an extra shaft that came in the kit and you can use it to make the front diff the same as the back and the clicking will go away.
