STD-50URR for standard size outdrives (TT01R style)

To get rid of the bulky plastic dog bones and out drives I used some old TL01 axles, the TT01 hopup outdrives (#53790) for the gear diff, and 39 mm steel dog bones (also old ones from a TL01). There are Tamiya Universals for the TT01 pn53792 (TA04/TT01 universal assembly)
