when you say hardware, you mean just the electronics hardware or the strut and rudder as well?

if you mean strut and rudder, the rudder could be used, but the strut isnt the right type...you would need one like this

you would need a different motor mount as well

make sure when you mount it that you angle it downward so its pointed to where the strut will be....you can take a peice of wood and cut the angle into to do this...

besides that, all the other stuff should be able to transfered to the scat cat...you wont need the trim tabs or the turn fins though...
