I read some things regarding the diffs, and I guess many didn't like the orings and had sealing problems. There are
Kyosho gaskets tho that are a perfect fit and keep the diffs sealed.
I just got one too

but...... I screwed up the 10% coupon on ebay I had and didn't get it applied before I paid....

<----me to myself.
i'm hoping he can cancel the sale so I can rebuy it. I was trying to hurry as my wife was giving my boy a bath and messed it up.....DOH!!!!!!!!
