No, the Focus II is a good match as long as the final package weighs in at about 10.5 lbs. The SAP would be way too big for a Focus Sport (which is no longer being sold as far as I know).

But it took some effort to keep the weight of the Focus II around 10.5 lbs. The big factors that kept the weight down were getting rid of the fiberglass pipe tunnel (which won't fit the ES pipe anyway) and making a balsa-lined pipe tunnel (see page 12 this thread), using much lighter control horns and linkages than the stock ones, using CF landing gear and wing tube, using the Syssa Ultra IBEC (Tech-Aero) and the Tech-Aero failsafe switch/reg.
