Tamiya Terra Scorcher H-Arm

thingiverse

Front and rear H-Arm/A-Arm for a variety of vintage Tamiya 4WD buggies (Terra Scorcher, Fire Dragon, Thunder Shot). This is pretty similar to the original. I did remove some of the fillets/chamfers on the upper/lower surfaces to make it easier to the print but otherwise structure is very similar. I did remove the upstop and downstop feature from the arm which should help with loading. Ream the hinge pin and shock mount holes with a 3 mm drill bit. Tap the stabilizer mount with a M3 tap. NOTE: I have printed and done a quick fit check but I have not thoroughly tested. The original arm is pretty flexible as it is made of nylon, so printing this in PLA/PETG/etc. will likely result in a stiffer arm - but may break more easily. I may design a more solid version that is more inline with the DF01 arms, but that may come later. There is definitely opportunity to make the inner mounts much wider. If there is a strong desire to add back in the upstop/downstop geometry, that could probably be done.
