no it is not covered under warranty... you stripped the gears either due to incorrect mesh, loose engine screws, bad crash or truck was stuck and you continued to floor it..... This is a great truck, but there are some things that you have to do before you go out.... Tighten screws.......#1 reason for gears stripping.... It is not difficult to fix... I can do it in about 10 minutes now... You will need a split ring plier..... Buy an extra set... You'll eventually need them.... and locktite any metal to metal screws.. Nitro engines are known to remove all screws that are not glued in....
