How fast can the onda board go?

i have been longboarding for about three years now and im interested in maybe purchasing an onda board. im a speed demon and i want to know how fast these boards can go and if there good for downhill carving. everyone who has one of these boards says good stuff about them but i cant seem to ever find videos of these things going really fast. i also like to carve and make quick turns and do tricks so im kinda iffy on this board. the looks dont bother me and i kinda like the design. can these things slide? thanks to all :)
