I was just thinking the other day... What are the pros/cons of a boxer engine vs a vertical move (standard) engine? I would think that horizontal movement would be less stable (less robust) and more prone to failure as you have gravity allways pulling the cylinders downwards and off their axis of movement. How does the boxer engine compensate against this pull? Ideally, one would want the cylinders moving perfectly up/down to avoid this gravitational bias.

Could this also be at the root of the RMS and/or IM shaft problems we've discussed here? Just a cummulative effect of the slight gravitational pull over millions of cylinder cycles. Just wondering...

Disclaimer: I know nothing about mechanical engineering, so my question may be very stupid.
