Exhaust Bottom of exhaust pipe has oil on it

Inside of my Grubee and this was just a small part of what was in it. All this wiped out and was very gritty. But some do not have a clue as they thing it is break in oil. I do not want grit going throw my motor.

It will come out.... Eventually ;)
My skyhawk didn't have any grit or dirt in it

So you took it ALL apart and checked it? Both my eBay motor and Grubee had way too much in it. I will never run one of these motors without taking it apart.
