Just found this link from the Locostbuilder site, and had to share it here.

Makes you realise just how hard the engine wroks!!

Ouch, that made my ears hurt!!

Ok, That even surprised me and I know how hard these engines work

Just in case anyone doesn't know much about engines, the cams (as seen in the video) actually only rotate at half engine speed. So the crankshaft is rotating at twice the speed of the cam shown there.

Just imagine how fast those pistons are moving!

The amount of valve rotation makes you realise how important the valve spring seat is.  Great vidio

I didnt see any wrok Bri...It seemed quite steady to me.

Nice to see how the engine works though. lol    Nice one.

Its a wonder how the valve collets stay in place at that speed.   And think of the slap every time the valve hits the seat.   Wonder it works at all.
