I have succesfully moded the Tamiya Sand scorcher steering and would like to share it with you
here we see a futaba bls servo mounte on chassis using some old kyoshos inferno radio tray mounts
the servo rod is from stack reinforced with some old fluo yellow antenna tube
yellow antena tube bolted onto servo saver and ball link onto top
i also drilled and bolted the servo saver backwards as when the vehicle steered right, servo savers arm would bump to front limiting right turn radius
i hope i gave the solution to the tamiya ss steering problem.Enjoy this great rc car
