It looks as though the champ at 1:00 goes forward a lot slower than it should, when compared to its backwards speed. I mean proportionally, as we all know that forward and backwards have different speeds.
I made that sprinkler work when I received it, it was not working nor would it move. I do agree I would think that the forward movement should be faster, but since it is a tube style PJ arm that I bent slightly to the right so that I might get a little better movement and also added a spring above the bearing sleeve to get the stability that I did not have as these sprinklers of which I have several, had issues besides they had been oiled or some sort of grease was used on the bearing nipple which stopped them all from working. I had to do some cleaning to remove that gunk. I focused my working with one to do my experimenting to see what it was going to take to get it working half decent. I took the spring off of a spoon arm model and that worked. The springs they use I think are too stiff. I took a spring off of a new sprinkler and feel it worked better as it was not quite as stiff. I am also learning to make my own springs that are a little less stiff on the bearing sleeve. More experimenting to come when the weather warms up enough.
Nice 👍
Nice compilation! I too like the champ at 1 min. It runs well on your setup
This is one of my favorites.
Nice compilation! The Champ, I believe at 1min has quite an extended distance control flap.
that Champ is one of my favorites. I like the timing and the way it moves.
