Oh, I didn’t know that! Either will work very well if built correctly, but I’d say a 4-bar is more reliable. @infinitechVEX congratulations and you’re welcome!
A little late but a 3:1 does not need any rubber bands if built well. My old one could pick up a mobile goal along with 7 cones without any elastics.
I had 1:3 and mine was built well, but since we used a X drive the lift had to get the mogo over the wheels. So the arms were very long, so the motors needed 1 rubber band each side.
@meng @Baguette123 Sorry, I forgot that there were multiple lifts… It’s a rack-and-pinion lift, like 8059Z’s old one
