Picco JL .28 Nitro Engine Ceramic Bearing Upgrade, Install in Mugen Truggy

I picked up this Picco nitro engine on offer up for $200. Picco .28 engines are hard to find. This one looks pretty new. The guy said he ran a couple of break in tanks and that was it. I decided to put in some ceramic bearing to give it a little more top end. I don't have me driving on Camera but this thing is insanely powerful.

The Ceramic Bearings I used.
