Double reverse four-bar

Hi, this year I am going with a double reverse four-bar. Does anyone have any tips on how to make it fast but also stable and strong enough to hold the weight of plenty of cubes. I plan to have four motors lifting on it.

Aluminum screws are your friend, box screws are your friend, aluminum C-channel is your best friend, stable support towers are your best friend.

Well yea I can see that being pretty obvious. The big question is if I should change the inserts in some or all of the motors

Are these v5 motors? If so, you do not need 4 lift motors, that is completely overkill.

-Do not use 4 v5 motors, use 2.
-Focus on having seriously reduced friction so that the motors do less work.
-Do not use shafts, use screw joints.
-Make your lift as skinny as possible.
-Use rubberbands.

Don’t put the towers that the whole lift sits on at the very front of the robot or your going to run into some tipping problems.
