Picco Otto .21 On Road Nitro Engine with DLC coated crankshaft Ceramic bearing for my BMT 984

I found this engine on eBay for $160. This is by far the best engine I've seen so far. DLC coated crank and ceramic bearings. The engine is a 7 port high revving engine. I'm still trying to dial in the carb. Seems to run better on my Byron's 30 percent nitro fuel.

Nice Synthetic caster oil race fuel
