When I put the launcher together I discovered that the opening in the Quest launcher would not fit the plastic pop bottle opening, I theorized that the rockets must have a special adapter for the bottle. I purchased the 6 rocket set and sure enough there were 6 adapters for 6 rockets. As soon as I got back from the hobby shop I put one of the adapters on my 24 ounce bottle water rocket and did some launch testing. Unless you had a funnel with a really small outlet, it will be necessary to take the adapter off the bottle to fill it. The adapter has to be on tight or it will leak, by design it should leak after 80 psi to prevent putting too much pressure in the bottle.

Another thing I really hadn’t considered was how the stability of the rocket would change as the thrust nozzle was now farther down on the rocket. First couple attempts at launching and the rocket was doing spirals in the air, sure sign that it was not stable. The only thing I could think to correct at the field was to cut a slot in the top of the rocket and put some coins in through the slot to change the balance point. First I put in a quarter, then a penny, and finally another quarter. It did really help but the rocket was going too horizontal from launch. Changing the fin design might help my design but next I want to try to build the rocket with the included materials for fins and nose. The distance was pretty good on the last launch but it landed in really tall weeds and I was lucky to find the rocket.

As a comparison I took out my PITSCO Aquaport launcher and the same rocket launched near vertical. The stream that comes out the Quest launcher is smaller but still accelerates my rocket design really fast. If the included rocket is used I think it will be slower because of the greater drag in the rocket design, which might not be a bad thing. I plan to report on this again after I have new rockets to try but I am optimistic it will work well as designed.
|Large Parachute Rocket|
|Parachute Fails to Deploy|
|Pieces Shatter from Crashing into Road|
Since my testing was over tall weeds, I brought out my latest rocket with parachute recovery. This rocket was based on another one that had worked well but this one crashed on the first launch breaking the fins off. As my luck would have it this rocket went darn near straight up except a little behind the launch spot and did not drift with the wind at all. The parachute did not come out and it looks like it was going to hit my parked vehicle but crashed on the blacktop directly behind it. This time the fins didn’t come off but the rocket broke in several other places. Rockets aren’t always easy.
