Relationshipware StratoLauncher IV Water Rocket Launcher + StratoFins

Relationshipware StratoLauncher IV Water Rocket Launcher + StratoFins

Q: Can you use without water?

Yes, our StratoLauncher IV is designed to use with various fuel sources such as: air only or air and water, as well as dry ice and water although the latter can be a little tricky and dangerous. Not recommended and messy would be things like air and flour, cream of wheat, and similar dry cereals although these do not perform that well and leave a mess behind unlike just air or water.

Q: Is there a way to fit a remote release? Also, what kind of altitude meter can I get? Thanks

We have plans to develop a remote release this year, but that may take some time. Currently the 10 ft. cable is as remote as it gets. We will be coming out with a cable joiner in the next month or two that will connect another 10 ft. cable making it 20 ft. and it should allow multiples of these if you want to be even further away. Concerning altimeters watch the video link below about mounting an altimeter to a water rocket: https://youtu.be/26iMMAWt3gw Under the description you will find a link where these altimeters are available.

Q: what is the bottle of blue liquid for?

It is 242 Blue Removable Threadlocker for sealing all the fittings that screw into the launcher body. You can see the application of it in the assembly video that is linked in the instruction PDF and it has been uploaded on Amazon as well. It does take 24 hours to cure and harden before you can use the launcher, so plan accordingly.

Q: How many nozzles come in a kit? (Not including strato fins)

Only 1 nozzle comes in the kit, which can be used on the StratoFins or used without the StratoFins. The StratoFins do not come with a nozzle, since they were designed and sold to be used on most any water rocket launcher whether it uses a nozzle or not. If you need additional nozzles they can be purchased on our site (StratoFins.com).
