Is it legal for me to hold one joystick normally and put another upside down underneath? (I would connect them with vex parts, no worries there.) The advantage is that I have 8 trigger buttons, which is plenty. Of course, I’d connect them with the partner cable. Is there any ruling against this?
Provided the Joysticks are not modified in any way, this would be legal. Please see this similar Q&A post: https://vexforum.com/t/answered-screwing-controllers-together/44360/1
