Spec-R TRF417 & BD-7 Version 2 front spools
Spec-R introduce their version 2 front spool axles for Tamiya TRF417 and the Yokomo BD-7 kits. Both build around an aluminium spool body with the axles now coming with hardened steel outdrives that are of a new design with machined sections for a lower weight while retaining the needed overall rigidity. The TRF417 variant sports a lighter Tamiya blue colour while the BD-7 part is available in darker Yokomo blue.
