It's only an update number rather than a milestone. Perhaps we can do something on the 5th anniversary of our first rocket launch? That's coming up mid next year. :)George Katzhttps://www.blogger.com/profile/05735356042927822858noreply@blogger.comtag:blogger.com,1999:blog-38795037.post-15708312249512978132010-10-12T21:19:58.630+11:002010-10-12T21:19:58.630+11:00Hi Charlie,

We really need to have the fins as stiff as possible as there will be significant forces on them when the rocket is traveling 350km/h+. (as the simulator says)<br /><br />But reinforcing it with fiberglass may work. I think we have some 3mm stuff on hand, so we may give that a go.George Katzhttps://www.blogger.com/profile/05735356042927822858noreply@blogger.comtag:blogger.com,1999:blog-38795037.post-65069205665998321392010-10-12T21:00:33.133+11:002010-10-12T21:00:33.133+11:00Last comment - I also note DAY 100 is something sp...Last comment - I also note DAY 100 is something spectacular going to happen???? water rocket fireworks - Apogee air explosion with confetti (LOTS). The new Big Rocket?? What about a glow in the dark silume charge instead of water??Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-38795037.post-36018311740891807642010-10-12T20:56:49.866+11:002010-10-12T20:56:49.866+11:00Air Command - Another thought.

Also if the jet is is directed through the ring fin - any air on the top side may be sucked through by venturi - further reducing drag on the rocketAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-38795037.post-80595332457585006052010-10-12T20:43:33.389+11:002010-10-12T20:43:33.389+11:00Air Command,

Does not need to be strong. You can superglue to the bottle - and it it has a hard landing - it just breaks off at the bottle perfectly intact - and can be glued on with superglue again in ~2mins with little effort. ie. you could also just fibreglass the 2mm corriflute if you like a better finish. Or dip it in a hardener if you wanted to harden up the internal ribbing..This material would be hard to beat frf lightness.<br /><br />Charlie HAnonymousnoreply@blogger.com
