Enthusiasts tuning the TRF201 will find the Tamiya 54245 aluminium rear upright a neat upgrade. It gives a 0.5-degree rear toe-in that improves traction in bends, while the robust aluminium construction and upsized 1350 bearings lower maintenance demands vs the smaller 1050 bearings.
The Tamiya 54245 is designed for TRF201 applications and also suits DB01 and TRF511 setups, making it handy for pilots who switch between models. The larger bearings smooth out rear-end behaviour and reduce the number of bearing services over time.
