here is a hydro that i have built it is small and fast
there is a wite up on it some where on RCU but (lol) i cant find it
well i have a mini brushed peakradier motor in it and the -mini-t electronics and the servo !
the rudder is for expermental pourpouses only so it may look weird
and it is running on a 6 cell pack but will soon run on a 11.1 volt lipo and if that goes well i will be putting a hacker BL motor in to it !

here is a vid of it its just reving cuz i have no water ! lol

lol BTW in the vid i said it was a "tunnel hull" i dont now what i was thinking lol just disregard what i said !
