The Next Evolutionary Step

After a bit of a hiatus I am delving back into the electronics for this again. The idea of using a commercial flight computer for this system proved I could get something useful working, but it was lacking in a couple of areas. Of particular concern was the autotune algorithm tuning out the vertical...

Starting a Rebuild

Time to Resurrect my Nike Booster For anyone who has been following this project you will be aware that it became the booster for my half-scale Nike Apache that I flew at Thunda 2019. While the sustainer made a nice flight to 37500’ the booster came in ballistic for an unplanned core-sample. This i...

Re: Lack of posts....

I have noticed the same thing. It has been getting less and less for quite a while before covid. Personally I have not been doing much rocketry due to work and lack of enthusiasm for lots of things. Last year was one HPR launch (O-M two stage) but not many other flights due to weather, crops and fir...

Re: AMRS Insurance

Can someone who directly knows anything about this confirm the status please? If the answer is unpalatable the members still deserve to know the status. Lack of information causes rumors to spread.

Re: Launch disappointment......

I can't believe they went that far for a launch and didn't have spare igniters. Beginner's mistake.

Re: MacPerformance Firestick XL - my level 2.5 build

Looking great! You could try vacuum degassing. You just need a small vacuum pump attached to a flat plate you can put over the mixing cup. I have been known to use this method, using a small two-stage diaphragm pump I have. No need to break out the rotary pump for that one! Worked well with West Sys...

Re: Hiya Everyone!

Hi Crabby. Welcome to the forum. Lots to see and learn here. Swinburne uni has a high-power rocketry team I think. One of our club (Tripoli Rocketry Association) is mentor to the group. I can point you at them when I find out who. Personally I am mentoring USYD, even though I am based in Melbourne. ...

Re: Modular Rocket

The overall method seems sound, though in future I would install the hard point before painting.


Nobody has ever done that before. :P

Looking good.
