Rookie / Centax: have no idea what partnumber Ofna has on it, the original Hong Nor number is: #336 though.
Initial: No, I first did it for me... then I made a version for Serpent, then AE.
The gear chart is only AE NTC3 though!
Do note, since page 195 in this thread I've been posting some tip on some things: an easier adjustable front swaybar, foam+foam front bumper, new partnumbers for the new version 2 Nitro TC3 cars (including the Factory Team) and also posting some tips on the building of my own FT-NTC3 with version 2 rear suspension etc. If you just jumped in this forum, you might want to jump back ta page 195 and forward...
