Thunda Down Under launch 2015

Postby kitestring » Mon Jan 16, 2017 8:18 pm

Hi George, i was just reviewing some vid from 2015 and noticed quite a lot of flex in your rocket at launch. Seems only visible from this slightly side on view... We were situated at the far left of the range. The shot was taken through a DSLR L series lens so no chance of lens distortion Thought you may be interested?

Interesting, could that be lens distortion?

Awesome photo Jeremy. 8) Thanks for posting. I can totally believe that is flex in the rocket. We have seen this before in our smaller long and skinny rockets made from FTC (Fluorecent Tube Covers). In fact the bend was so bad that it sheared the nosecone off and deployed the parachute during launch.

Do you have more of the footage? It would be interesting to see how the flex progresses during launch.
