Our launcher will generally not stay at the set angle – even with a lightly loaded straw attached to it. I see a couple of rubber o-rings – is there any way to tighten it up a bit so the kids can set it consistently? It continually lowers down.
Pitsco suggested that the coach remove the tube (it just pulls out), and wrap a few wraps of teflon (plumber’s) tape around the tube where there is the obvious mark on the tube caused by the slipping. They report that this solution has tightened things up for all of their customer’s so far. If it does not work for you, please let WESO know and we will continue to investigate solutions.
