Looking into buying a cat-twin electric. probably 34" or larger, and needs to be fast. Would like 70 plus mph.
Dont know the first thing about em and looking for advice where to buy and what hull,motors, batteries etc.

Check out screamandfly.com, they have an R/C boat forum on their site

I have a 2 stroke Hydro well into the 90's

54inches long

I just picked this up but have not run it yet. My friend is real big into Rc's and he turned me to this one. We were really inpressed with the fit and finish of the boat. It looks great and has the new brushhless outrummer motors..

do a google search for Hanspeter rotschi , very cool elect cats !!!! 70+ to 90 + inch cats .or swiss model powerboats

Cant believe there is a post inquiring about a cat and none of the usual suspects have warned about "INSURANCE"

I don't own...but have been intrigued with Bonzi Sports line of rc's. Looks like they've just added a cat line as well.
