Re: The Magic Pre-Launch Check List

Developing a checklist is part of your growth in your rocketry, similar to working your way through the HPR cert levels... Possibly true in some cases, not so much in others. Depends entirely on the individual. Some people need more assistance than others. The way I generally approach a task like t...

Re: The Magic Pre-Launch Check List

I have a nice checklist for my L3 which I will attach to my thread when I get back to Oz. A general purpose list will not work for all rockets as the different configurations have different needs. Having a general purpose list will reduce the chance you have forgotten something important! It will wi...

Re: Difuminar: 9500 feet and Mach 1.5 on a CTI G150

Looking good. Remember to treat the GPS unit to some glue on the antenna (epoxy to the PCB) so it doesn't come off during the savage boost. The ceramic patch antenna is only held on with double-sided tape and one solder joint normally.

Re: Looking for some advice - new to rocketry

Welcome. Not sure where you are located. I suggest approaching a local club, and maybe going to a local hobby shop (or Australian Rocketry) and getting a small model that perhaps flies on maybe D motors or thereabouts. Follow the instructions and build the rocket (ask questions here too if you need ...

Re: MARS April Launch

Looks like everyone had a great day! Sorry I couldn't make it guys. Rocketry is dead in the water for me currently, and my car is in pieces. :( Hopefully it will be back on-line in a couple of weeks (after returning from a work trip). I might even make it to the May Tripoli launch if I am lucky. Fin...

Re: Aerotech Afterburner

That's amazing footage. Looks like some unburnt fuel makes it through the nozzle into the exhaust plume. Maybe it is that the particles are hot enough by then for better ignition/burning.

Probably makes for a great sounding launch :)

Re: Where to buy 2302 igniters in Dandenong/Melbourne?

Most of the LED replacement bulbs, like the one pictured earlier in the thread, have the resistor integral with the assembly. That makes life easy!

You can add a LED youself, and you will need to put a resistor in if you are just using plain LEDs, as Raaahbin explained.

Good to hear you are back in the air!

I like the idea of changing your globe out and putting in an LED. V.simple!

Re: Where to buy 2302 igniters in Dandenong/Melbourne?

I very carefully insert the igniters into the motor, and with it off to one side then push the plug in. Don't make the mistake of thinking it has to be absolutely in the middle. They are fragile and I have suffered from broken ones in the past, and also the odd shorted wires as mentioned above. They...

Don't really want to trek all the way into the CBD just to pick up a $10 pack of igniters.


They also have a good range of kits, so you can enlarge your fleet :D
