CenterStage Specific

From a conversation with John Collins, a Guinness World Record Holder for paper airplane design.
A new resource from FTC elaborating on the rules for what makes a legal CenterStage drone, along with examples of allowed and prohibited designs.

FTC Hardware

Instructions for how to run more than four motors from a single Control or Expansion Hub using a REV Spark Mini. Westside Robotics have a number of other tutorials available as GitHub repository wikis.
The information on this site is not very current, but it does provide some insight into different parts of the hardware system.
This document from REV identifies the actual gear ratios for ultraplanetary gear cartridges. The naming of each type of cartridge is based on a nominal ratio, and using the exact ratio may be important for things like calculating distance based on motor encoders.
