393 Motor Electrical Repairs


I have like 20 393s that are broken (wires come un-soldered from the circuit board). If I solder them back together, will they still be legal?

Thanks. Also, you don’t need to flex your regular powers by changing the title of a secondpost of mine.



You too @Xenon27



umm I beg to differ. fixing 393s are perfectly legal. now modifying them ex. replacing the motor inside IS illegal.



you would have to ask (or check for an existing answer) on the official Q&A at robotevents.com, for an official ruling, however, rule R16c says

c. External wires on VEX electrical components may be repaired by soldering, using twist/crimp connectors, electrical tape or shrink tubing such that the original functionality / length is not modified in any way. Wire used in repairs must be identical to VEX wire. Teams may make these repairs at their own risk; incorrect wiring may have undesired results.

so opening the motor and making internal repairs has always been considered to be illegal.

The only exception to making internal repairs is

b. Internal or external mechanical repairs of VEX Limit and Bumper switches are permitted. Modifying the metal arm on the Limit Switch is permitted. Using components from these devices in other applications is prohibited.

it was allowed last year at nationals



It shouldn’t have been allowed. It may have gone unnoticed (as the only way to detect such a modification is to actually open up motors), but it was still illegal.
