Kyosho 92922 adjustable servo saver arms

thingiverse

This is a replacement arm set for adjustable servo saver shaft. Kyosho part number 92922. These same arms are used in several Kyosho models such as the Ultima ST Type-R/Evolution, SuperTen, PureTen etc. Print with 0.20 layer height and 100% infill. After printing, slightly sand the surfaces that move against each other so the layers do not bind together and the servo saver moves smoothly. I ran in my own servo saver by twisting it several times once fully assembled. I also used silicone diff oil between the surfaces. The servo saver tube/spring/nut part number is 92921. However, I do not know if newer versions are compatible with this design. UPDATE! Kyosho DBX shaft is identical to the old 92921 set. I can confirm this because I ordered it and it just arrived. So the replacement part number is TR133. This is much easier and cheaper to get than 92921. The bearings used in this design are the stock Kyosho recommended 5x8x2,5mm. You will need four of these.

I just got my original Type-R parts and they differ from the ball joint locations of the Racing Sport version. Compared to the Racing Sports version, the Type-R outer ball stud locations are almost 2mm inner, so the Racing Sports version ball stud location causes excess TOE-IN. I have now corrected it and uploaded the fixed design file. So these updated arms are "with the real Type-R steering geometry". When installing the steering links to these arms' balljoints, do not force the ball joint ends in the balljoints. Use pliers to snap them in. If you bend these arms too much downward, you will break them. I can reinforce them if people want it, but the idea is for them to bend a little in big crashes, but not on normal use, so you do not break or bend something else like those rare Type-R king pins, or hinge pins, or steering hubs.
