Windy Launch at Mullaley

On a recent trip to NSWRA's HPR launch site at Mullaley the conditions were less than favourable, and so we didn't get to launch our big Polaron G2 rocket. In the 30km/h+ wind conditions I don't thing it would have even been possible to make it stand vertically. So here is a highlights video from the rest of the day. 

Although a little dissapointed, we were still happy to catch up with club members and watch some of their rockets launch. We'll be back at the launch site in September for another try. (Hopefully also with a new rocket project we've been working on ;) )

How to measure the altitude of your rocket

Earlier this year we looked at 4 different techniques for measuring the altitude of a water rocket. We used all 4 techniques on the same flight so we could compare them for their accuracy. We repeated the experiment 3 times just to make sure. Here is a highlights video that looks at the results as well as the reasons for their differences.
