Alright, so this friday i went out on the track. Some wet spots and plenty of
mud, no problem! took the maiden voyage for making a few backflips because
even if i intend to make my revo into a racer i want to have some fun with it
as well (gonna get another truck for bashing later on, tips anyone?).

Anyway, by the end of my session i start to hear funny noises from the car,
and by funny i mean noises you do NOT want to hear from it.

Brough it home, took off the engine and checked it best i could for cracks and
the like, checked the piston and arm and everything where still whole and shiny.
Proceeded to the tranny, alright there were a little rock who got stuck
between two tooths on one of the plastic gears (#5395) but hadn't made any
major damage which could cause the funny sounds. Going to get a
replacement for the gear soon enough since its still usable.

And as for the end of the story, proceeded to spin the tires a bit and
hearing the sounds again from the rear diff. Oh great....To my surprise upon
opening the diff case i find that all the gears inside are whole and well, just a
bearing who had broken and the bearing balls were scattered around inside it.

Is this something who happens alot or am i just a unlucky fellow who will need
to spend a $10 or so for a new bearing and grease? And while I'm at it and the
truck pretty much in pieces, should i check something else? Already spent
$300 on it this week alone and would like to be able to drive for more than an
hour before next thing happens.

Some bearings just last longer than others. Its a good idea to have replacement bearings on hand when then need arises.

Check out Avid RC, you can get almost any non ceramic bearing for $1.00.

I have had that happen only once on my savage. Could be either the result of a worn bearing or a factory defect.

Probably, but since i live in EU things costs alot more due to shipping and all that jazz.

Yeah, most likely worn out or factory defect but who knows. If it happens again then the
fault might be with the driver himself. :p

Ordered a new gear and some bearings so i've got a few laying around, damn i need either
A) bigger desk or B) another desk which is dedicated to the hobby because this is taking
up more space than i imagined.
