Hello rocket raz,
wellcome here.

Bäckchen

Welcome Rocket-Raz.
Beautiful Model!
We have already a Scale-Thread somewhere here . You can watch there Robby's Tin-Tin Rocket (does'nt fly) and my V2 Rocket.
I had problems with the parachute too. I can't build a Tomy Timer in my V2, so it doesn't fly any more... I hope your next parachute-system works. Would be sad if not and your rocket lies around like my V2

Hi Rocket Raz
welcome to this WAROCKET community.
Thats a great rocket!!
Have you used simmetrical splice?

Hey Rocket-Raz! Welcome to our little Waterrocket community (I believe it's the best on this Planet) Your Rocket looks great! As I can see, you use the normal Gardena System, don't you think you could reach larger heights, if you'd use the Pro-System?

Wow,it looks really good.
How does your parachute-system works??
And what glue does you use for the Symmetrical Splice ???

Hallo vielen dank für die antworten auf mein erstes bildchen ich entschuldige mich gleich nochmal wegn der grösse aber das muss euer pc halt ab ^^

UND hier meine neuste mit gardena ( kleber ist UHU Endfest Plus 300)



So hinter der Kupferpladde verbirgt sich das Ventil der schlauch ist insgesammt 6 m lang und ich habe aus dem chemie raum bei uns nen gummiestopfen gepfeilt ( ja echt das geht) und dann in den 1/2 " schlauch gepresst und festgezogen mit dem ding da (habe den Namen vergessen aber erfüllt seinen Zweck).

Nun muss ich nur noch das auf die alte Rampe packen.

Tach!

Ich hab mal ein Video von rocket-raz´ Rakete auf meinen webspace hochgeladen,
da er selbst keinen hat. Hier ist der link:

Very fine, rocket-raz. But this fligth was not very high. It seems, that the chute
opened too early and stopped the rocket.
What kind of deployment system do you use? Could you make some pictures
of the details of your system. A lot of people are interested in that.

Greetings Robert

Sure, that might be the point.
But it got to a quite moderate height due to the short time of the actual flight!
Maybe a remote pressureing/starting-system might increase your partner`s health,
also you simply kept it somehow people call "KISS"

Hichi das sieht ja schon gut aus! Deine Finns gefallen mir gut! wie hast du die festgemacht? Wozu sind die Nieten?

Hi there

First. Thanks for all the kind comments, and help you have been giving me.

I use 90sec epoxy resin for the symmetrical splice. I have tested the bottle to 7 bar of pressure. Can't test it with a higher pressure since I am forced to use my dads compresser. In the flight shown in the video that robby has uploaded I filled the bottle with approximately 33% of rocket "fuel". The fuel is made of 67% water and 33% soape. I use this mix, since it leaves a breif foam trace on the sky. I pressurized the rocket to 6 bar via the Gardena system and launched. The entire rocket as launched is at the picture below. I know that I have teaken the nosecone of, so maybe the reduced highed is because of higher drag. I removed the parachute section off for this flight since I just cant make it work. Am going to work on it today, the problem is that the parachute won't come out of the chamber.
@ Speckknoedel, you talk about a pro-system. What is that??

The second photo below shows the rocket at the launchpad including the parachute section. The weight of the entire rocket including parachute section, but without water is about 190 grams. And the nossle diameter is standard Gardena I think about 10mm.
