Question 1

What is the difference between the deluxe kit and ultimate kit, other than cost?

Accepted Answer

Both the Deluxe and Ultimate models are exactly the same other than the Ultimate includes 4 additional parts, which can be purchased as an upgrade kit separately if you buy the Deluxe model. These 4 additional parts are a mini ball valve, a Quick Release M Plug, a Quick Release connector, and a 1/4" NPT barbed fitting. This creates the Quick Connect Water Fill System that attaches to an inexpensive 2 gallon tank sprayer, which you would need to buy from a local hardware store. Our water fill system fuels a rocket very quickly yielding about 30 launches with a 2 gallon tank and makes transporting water to the field easy without having to drag additional jugs or bottles of water along. Thank you for asking the question. If you have any more questions, we are happy to provide answers.

Question 2

So i see this uses Gardena style nozzles. I know that standard Gardena nozzles do not fit bottles, so where can i get addtional nozzles??

Accepted Answer

There a few shops online that sells them, you can also 3D print them

Question 3

Do I really need the 2gl tank sprayer to properly operate this launcher?

Accepted Answer

No you do not. If you are doing many sequential launches, it does make it easier/quicker to hook up a tank sprayer to the launcher to fill the rocket. If you are using a tank sprayer, you just lock the empty rocket onto the launcher, turn the ball valve on the launcher to open the water inlet that the sprayer is quick-connected to, and close it when the desired amount of water has flowed into the rocket. If you don't have the sprayer, you just have to fill the rocket each time using the funnel before you place it on the launcher.

Question 4

Can I use a higher tank spray?

Accepted Answer

Not sure what you mean by a higher tank spray, unless you mean a higher than 2 gal. capacity, which is what we typically recommend. If that is the case, than yes you can use a higher volume tank or a taller tank or even a higher pressure tank sprayer. The restrictions are not on the tank sprayer, but on the amount of water that fills the rocket, which should be limited to about 1 cup of water. A 2 gal. tank sprayer will yield about 30 launches. The other restriction would be the max PSI for pressurizing the rocket, which is 120 PSI and the safety valve will release at 125 PSI. I hope this answers your question otherwise please provide more detail when asking your question.
