Re: Green Tree Frog

Animals can behave unpredictably sometimes. I was zeroing a scope on a rifle at a friends farm many years back. There was a calf in the same paddock as me, probably about 20-30m away, and the target I was shooting at. She would watch me, and when the trigger was pulled she then looked towards the ta...

Re: Lost rockets page

Hi Kopius. I am still missing the Apache sustainer from my O-M flight. Silver, 75mm airframe. I would say Thiokol label on the side but M2.14 may have ripped that off.

Re: Large and Dangerous Rocket Ships

Don't forget that your local library usually has funds for new books. If you ask them nicely and provide the details they are quite likely to purchase the book :) . I actually donated a copy of Modern High Power Rocketry 2 to the library, and asked them to purchase two other books. Let's spread the ...

Re: Free Form Fins - CP Issues - OpenRocket

Make sure you fly with a decent size chute, as fins out the back are more prone to damage on landing.
