Drive4fun just get the right screw size at your local hobby shop
and make sure you endpoint adjustment on the servo throw
doesnt exceed the actual limit on the car linkage.
RE: centax
Ive seen a few local guys running the mugen centax on the
Ntc3 just make sure to but the mugen .8 gears.
Also you will need to grind a little of the rear brace for
clearance.
