Get sharper steering with Tamiya 54121 aluminum servo horn

For drivers seeking improved steering feedback, the Tamiya 54121 aluminum servo saver horn offers a straightforward upgrade. It replaces the Hi-Torque Servo Saver Q5 component to reduce flex in the linkage and deliver more direct wheel response.

Which kits and how to fit

This anodized blue horn fits a variety of Tamiya kits including TB-03, TA05, DB01, DF-03, TRF501X, TRF416 and TRF415. It can be used together with Spare Parts 50473 and 51100 for flexible mounting options. The aluminium build gives added stiffness while staying lightweight.

Yes, the horn is made to fit TB-03 and TA05 platforms as well as DB01, DF-03 and the listed TRF cars.
No special servo is required, but pairing it with a high-torque servo will maximise steering precision. The horn itself replaces the stock Q5 saver part.
Check the mounting screws and linkages after the first few runs. Re-tighten hardware and inspect for wear to keep steering consistent.
