Sorry, I miss read the original post (damn phone screen and tired eyes)! My answer was for the more common FS2 Vs FS2-sp question ... ooopppsss
Yes, FS & FS2 are both supplied with small bores.
There are quite a few differences between FS & FS2;
Chassis :- no cell slots and beefed up around the point the rear most front hinge pin holder bolts to the chassis (this was the place were chassis cracked if they were going to in a big cash or coming up very short on a gap jump)
Rear wishbones :- FS had the short wishbones, FS2/FS2-sp has the mid length wishbones
Rear hubs :- FS & FS2-sp have the UM519 hubs, the FS2 (and RB5-sp/sp2) have the UM519-2 hubs which have both camber link holes moved out 1/2 a step (so basically the outer and 3rd in position on the aluminum hubs where as the UM519 has the 2nd & 4th in hole positions)
Driveshafts :- the FS & FS2-sp both use the longer axle & the 62.5mm shaft (part number UM510) but the , the FS2 uses the short axle + 65.5 bone like the RB5-sp/sp2 which is part number UM522
Rear hinge pin holders :- the FS2/FS2-sp have the adjustable ali LAW36/LAW37 hinge pin holders where as the FS had the plastic holders.
Body shell :- the FS2 was the first to shipped with the drop dead Shoot shell the previous version had the Cannon shell which is much tighter for brushless + lipo instals.
There where lots of subtle hardware / plastic material changes between the two cars as Kyosho upgraded their specs on certain parts.
I think that has it all now, sorry about that.
Handling wise the FS gives the most rear grip but at the expense of some natural pivot, the FS2 has loads of pivot at the expense of some lateral grip and the FS2-sp has plenty of both grip & natural pivot = the perfect balance for a 4wd IMHO.
