I apologize for making a second question about this, but I was unable to edit my previous question to include the following details because the edit functionality on the Q&A is currently broken and has been since it opened.

In Q&A 823, it was ruled that the VEX clutch was not legal because it was attached to the servo. However, the clutch was also available separately in packs of 3 under the part number 276-1098. Previously it was common to harvest the springs from these clutches for use in mechanisms, and previously it was ruled that this is explicitly legal since the clutches are not necessary associated with 3 wire servos.

This excellent forum post outlines some of the reasons that this should be legal: www.vexforum.com/t/answered-removing-springs-from-clutches-r15-r5/24736/5?u=sazrocks

Additionally, there are several other cortex products which are now of questionable legality. Yaw Rate Gyro: www.vexrobotics.com/276-2333.html Analog accelerometer: www.vexrobotics.com/276-2332.html LED Indicator: www.vexrobotics.com/276-2176.html

While some of these products have been superseded by the V5 Inertial sensor, they are still perfectly functional on V5 and are even officially supported by official programming environments such as VEXCode. I do not see a reason these parts should be illegal for use with V5, and keeping them legal would help teams who are on limited budget to continue to use the advanced functionality that they provide. Is it the GDC's intention that these products be illegal?

In Q&A 823, it was ruled that the VEX clutch was not legal because it was attached to the servo. However, the clutch was also available separately in packs of 3 under the part number 276-1098.

As noted in the response to Q&A 823 - rules R6, R7, and R15 all reference the fact that the VEX product website is the most definitive resource for specific product legality. In addition to the 3-Wire Servo not being legal due to rule R18-a, both the servo and the standalone 276-1098 clutch are considered discontinued/obsolete products and have long since been removed from the VEX Robotics website. They are not intended to be legal.

Yaw Rate Gyro: www.vexrobotics.com/276-2333.html Analog accelerometer: www.vexrobotics.com/276-2332.html LED Indicator: www.vexrobotics.com/276-2176.html

These are intended to be legal. We will be sure to make this distinction more clear in a future Game Manual Update.
