Re: Model Rocket Survey

I filled this in for my high power rockets, if you would like I could fill it in for low powered rockets but I haven’t flown any for some years...

Re: Hoping everyone is safe

It is never good to see someone injured or worse due to rocketry. :(

This is why rocketry clubs have stringent safety rules which must be adhered to... and why everyone should join a club.

Re: Free Form Fins - CP Issues - OpenRocket

If your rocket is short and squat I think your design is just in the "sweet spot", but if your rocket is longer, SpaceManMat might be right. You can test for this if you make small progressive changes in each direction and graph the results of point location Vs. stability margin (say movin...

Re: 56er, ignite ork files?

Hi Pete, There are probably no pre-done model files. A simple rocket like that would not take long to model, Open Rocket will most likely have most if not all of the materials in the library. The most important things in a model are the CP, which the model will give you from the sizes of all the ext...

Re: Question for L3 flyers

My older sisters boyfriend at the time (called Walter) was into model rocketry and I went to a launch with him at Caulfield racecourse in 1973.

Re: Almost all motors on backorder

In my specific case I often order motors I want YEARS in advance. The L935 and M2245 I flew at THUNDA were purchased in June of 2015. TLDR; if you want something specific order it well in advance when AusRocketry announces a new motor order! I do this too Drew, I still have motors that are 5 years ...

Re: Square Mid Power Rocket

For flat attachment, you could always go TTW running the fin against the inside of the body. No need then to have the fin go all the way across to the other fin. If you keep the tab to about 10mm with roughened surfaces you would get a really strong attachment. :wink:
