hi Karl,

i`ve Rocksim 5 and 6 and I`ll sim it tomorrow, the outside diameter of the bodytube is 63,5mm and the fins are 3mm thick I`ll give her a 29mm motormount, that will be enough, i think she will be light enough to fly on F or G motors and if she isnt i can put a G75 or H238 or something like that in...
I`ve already the casings for this motors, i won them on the tombola at ALRS in September

hi,

the pic you`ve posted is the rocket Vision III, it flew on a Selfmade-Candy motor(K-Impulse)!!! you could fly your rockets there!!! Here in germany the AT and other motors aren`t certified, but we can fl them on this meeting, without any certifications, so everbody can fly L2 there, for example, that`s really great...

Marxi and me, were on ALRS this year, the Ariane was the biggest rocket flying i ever saw, I flew my MIMAS on a H123, i`ll fly it next year again at BC-Days 2k5(the link i`ve posted)

okokok, my sister won the casing, but she cant use them so she gave them to me,...

hi,

i`ll change some things on the rocket, i`ll make new fins made of Balsa(3mm) and then glass it, this time the fins will be TTW(through the wall), not to waste the work/material of the old fins, i think I´ll build 2 Jayhawks(for dragracing)!!

Only in order to get this right:

but we can fl them on this meeting, without any certifications, so everbody can fly L2 there
with this meeting isn't meant our ALRS, but a launch in germany, where they have instead of TRA/NAR their own certification system.
In Switzerland as a TRA prefecture you have to be certified for level 1/2/3 flights!

@roman: please clearly differentiate!

@karl: we would be pleased if you and other people of UKRA (and everybody else) would visit ALRS VI next year.

I've actually asked my parents about it, and they are considering it :D I would have to pick up motors & rockets over there because I think that the residue that ejection charges leave behind, Airports don't let pass.

(Ich habe wirklich gebeten, daß meine Eltern über es und sie für es:D halten, das ich Motoren u. Raketen dort würde aufheben müssen, weil ich denke, daß der Überrest, dem Ausstoßen Urlaub nach auflädt, Flughäfen nicht Durchlauf lassen. Karl)

In addition to Andy´s post:

In Germany it is absolutly forbitten to manufacture or modify motors without a permission (which is really! hard to get).

The K-motor was flown on a german EX lauch on a military area, with a special permission.
The owner of the Vision III is one of a handfull fellows, who made the long, hard and stony way throug the germany law-jungle to get this rare sheet of paper...

Roman,

The RockSim file from the Gates Brother web site for the Jayhawk is not very accurate. I made a better one for Martin Vrstal visit thread:

http://www.rocketryforum.com/showthread.php?s=&threadid=9918

or see the attached sceen shot. If you PM me or post the details I will create a RockSim file for you. If you have RockSim version 6 or greater I can even place the asymmetric fins on it for you.

hi,

I`m gonna PM you all details in a few days!Thx for that!!:D

everything i wrote about the launch, was about the EXP launch(BC-Days :D )

@Karl: you could send your rockets to someone(by DHL/UPS/etc.) who goes to the launch, i know someone who already did that...
