Last year our pneumatics would do this. Part of it was our brain being goofy and needing to manually set the pneumatics port to digital out low before every match. However, our stuff worked fine during matches.
perhaps add a rubber band pulling up slightly on the wings to solve the pistons not being able to start bringing them back up consistently? cool wings tho
The reason they shoot up and down quickly like theat is because the Pneumatics have four stages of out, weird thing, wierd thing, then in. Its nothing wrong with the robot.
I mean, just alternate them and it be flyin! But really, just as rubber bands to pull the wings back better, and maybe secure the cylinders in place a little better and you will be good.
