I tested a launcher destined for Sweden today, from the last batch. At 40 psi the ball went so high I just about didn’t get it back. Most of my Field Day launching this year was under 50 psi, and that was with a CSV17!

NOTE FOR HOMEBREWERS and KIT BUILDERS – the Harbor Freight (newly manufactured old style) trigger valves are not doing very well. Most are marginal flow-wise. We have a few old type valves in inventory but will have to do something different soon. We shipped some of the newer (bad) HF valves before this was discovered, so make sure and test your launcher BEFORE CEMENTING THE TRIGGER JOINTS so it will be easy to swap out bad triggers. 

Thanks for your patience,
