a little tip I found out for the motion link of gears, sprockets, and pulleys with odd ratios is to put the teeth of gear (or sprocket or pulley) A as the angle of Rev2, and the teeth of gear B as the angle of Rev1.
Thank you so much for making this playlist of videos. This has helped me so much in the preparation for the next FTC season (which starts today). I hope to see your team at some point! Thanks!
