Re: Cheezy Water Rocket Toy with Potential
have you tested it already? Or are you still stuck with the parachute?

No it is ready to go. Aiming for Father's Day since we'll need some space and have to travel to a park.

Re: Cheezy Water Rocket Toy with Potential
Here is the new upperstage. The rocket has been named Paso Doble

Re: Cheezy Water Rocket Toy with Potential
seems very nice!
It looks like a real rocket. ours looked more like a hotchpotch of pieces of junk and wasn't even straight. Only our parachutes looked good.

Re: Cheezy Water Rocket Toy with Potential
Thanks! It is a fairly simple design, just 1 2liter for pressure, The cargo bay is a second 2l bottle inverted with the bottom cut off. It screws into a cap glued on the first. The nosecone is the nozzle end of a 3rd 2l and is removable for access to the cargo bay. Using the USWR radial deploy, the shroud is made out of a 3 liter bottle. Kinda big for a second stage but that's just to make a point. The fins are balsa and are shaped to an airfoil so that along with grinding the nosecone was what took the most work.anoymous wrote:seems very nice!

Some pictures of Paso Doble ready to launch.
It is modular so it can launch as single or multi stage.

Re: Cheezy Water Rocket Toy with Potential
Hey so does anyone have experience siming a two stage rocket? My best guess is 400-500ft at 100psi. Total dry weight is 600 grams. 2l upper 4l lower.

Re: Cheezy Water Rocket Toy with Potential
I can't help you here. I never got past the single bottle rockets (at least not yet)

Re: Cheezy Water Rocket Toy with Potential
sorry for the double post, I forgot to mention that the rocket looks very good. Isn't there a recovery system for the first stage?

Thanks! First stage is "tumble recovery" or if needed I'll add a streamer.anoymous wrote:sorry for the double post, I forgot to mention that the rocket looks very good. Isn't there a recovery system for the first stage?

Re: Cheezy Water Rocket Toy with Potential
We have success!
And I have no idea where the upper stage is!
We had a false launch detect and then the alTImeter reported an error condition and wouldn't reset. So we launched with just the bare upper with no parachute, no beeping launchpad, and no blinking lights.

Here's the slow motion. There one second, gone the next.

Re: Cheezy Water Rocket Toy with Potential
Always look at the bright side of life: You can always make a new upper stage and you were lucky it didn't happen with the altimeter on board. you might have lost that too

I should probably start writing my phone number on the rockets :-)anoymous wrote:Always look at the bright side of life: You can always make a new upper stage and you were lucky it didn't happen with the altimeter on board. you might have lost that too
Onboard- HK altimeter with bluetooth dongle, 2 1s lipos.
Regardless of whether the upperstage is found, I'm happy because I just successfully launched my first two stage rocket, the airstart mechanism worked perfectly, and the glueless PVC coupling on one of the first stage bottles worked perfectly.
I suspect the alTImeter failure was due to low battery, so I will be checking on that.

Re: Cheezy Water Rocket Toy with Potential
How many launches have you used the battery? With us, after four or five launches the battery was low. We never had an error because of that, tough.
