I'm sorry if I seemed a little dismissive but we came on here to locate possible launch venues due to changes on our end. We are really glad that the comment about the G8 research status came up as it is very helpful to know we are on the correct side of the rules since our club flies under TRA rules and we were completely unaware of the possibility of a different status beyond just decertified. However the conversation turned into a discussion of our rocket instead which effectively derailed the thread and created half a page of unrelated discussion that anyone contributing has to wade through. I'll happily share our rocket design after we are done with everything in a separate forum thread but we are not taking modification suggestions from unknown sources here on the forum and I was trying to politely respond without ignoring or being too dismissive. I know this isn't my strong suite so I can accept some of the responsibility for this miscomunication. Nobody I've ever seen has launched weather balloons at a class 2 launch to establish upper winds for a rocket worth less then the balloon and helium.
