This may be a big problem with the summit... I know i liked going through water with my e-max and slash and never had any problems....But from looking at the summit i may have found a weak spot..... If water gets inside the front or rear gear boxes it may cause the lock unit to get dirty and sticky and cause all sorts of problems if it don't fully ingage it may get shreaded to bits! or may not work at all....If a little bit of dirty water enters in by the unit.....

Anyone else see what i am talking about?
