I've received my two cats to help grow my fleet, A rtr Mean Machine that I've already stripped back to a bare hull and plan on decking out with a 1717 and running 6s with a M545 for my driving and 4s with a de tounged x442 for the kids to drive as a learner boat. The other is a 42" Aeromarine sprint cat, this will have twin 1717's and run 6s2p per side, I'm a little dissapointed with it as I ordered the hull with a carbon fiber reinforced bottom and got a hull with 5" stringer rail's, oh well, I'll make it work.
