All about rotary
 

Thanks for sharing those cool videos!

I liked how the last video had so much informative info... all about rotaries :D:

Yes that video was a demo of the rotational limits of the pelvic region. I found it quite informative!

Yeah I'm guessing that it's still in development because the pelvic area looked to haven been worn and lacking adequate lubrication :rofl: 5w20 won't cut it :lol:
