Tamiya Boomerang/Hot Shot II/Bigwig/Super Sabre Rear Lower Arms

thingiverse

This is the rear lower H-arm for a variety of vintage Tamiya vehicles (Boomerang, Hot Shot II, Bigwig, and Super Sabre). This design is a modified version of the original. The original design was unique for the LH and RH side. This design is not - so it will work on either side of the car. It is also a bit more stout - so it will weigh more than the original thin walled (but still relatively stiff) design. There is quite a bit more material around the pivots - which should help with strength. Ream the hinge pin holes with a 3 mm drill bit (should not require much with the current clearance hole in the models) and tap the shock mounting screw with a M3 tap. The inner pivot may require a light filing/sanding. UPDATE 07/09/21: I have printed and test fit and made a V2 which has improved clearance to the drive cups at both ends. I have left the original in case someone prefers that design.
