Thanks mate, much appreciated. I'll have a look at the data sheet and order a handful for testing!

Re: Screw Switches

I buy Omron micro-miniature microswitches with arms (and wire pigtails) from Digikey, then build some structure around them. I get the sealed ones for improved reliability. Cheers OTT. Do you mind sharing which model you use. I did a search on Digi-Key's web site and they have 109 different Omron s...

Re: Another interesting find...

This was the only one on display in the store, but the bloke who runs it says he has a contact in eastern europe who can supply him with things like this. He has a lot of old deactivated soviet hardware, deactivated AK-47s and the like. I don't know what the law is like in Australia regarding deact...

Re: Multi Level Wind plugin for Open Rocket

Not quite sure what you mean by site specific. The wind models are constantly updated so you have to set your model for the hour and location you will launch and ideally obtain data as close to the launch as possible. A live web update feature would actually be fantastic but that's a future may pos...

Re: Screw Switches

So do y'all design your pull pin switches yourselves or are they COTS hardware?

Screw Switches

So I've been looking into screw switches recently. Basically I'd like to stop using the cheap push button switches I normally buy from Jaycar. Whilst they have worked flawlessly for me in the past (all the way up to Mach 2.2 in fact) I'd like something that's in a smaller form factor and a bit more ...

Re: Multi Level Wind plugin for Open Rocket

Not my work, but thought someone may be interested to try this new Open Rocket Plugin that allows you to set multiple wind levels in your simulations. I've not tried it yet, but with Westmar coming up it could be handy. http://www.rocketryforum.com/showthread.php?140619-New-OpenRocket-plugin-to-all...

Re: Hardware Choices?

On other tracking news it looks like there will be a new feather weight tracker, apparently Adrian has been working hard the last couple of months on this. No idea about an Au version or freq etc. Also you should all probably be aware the Raven 3 has just had its last production run due to its comp...

Re: Fin Thickness

Yea, what OTT said. 1/8 inch thick G10/G12 will be perfectly adequate. Make sure you use a healthy fin fillets and you'll be fine, no need for any FG or CF T2T work.

Re: Wallops - Sounding Rocket Mission May 16

I love the youtube video demonstrating the SubTec7 payload system undergoing final testing at Wallops. I'm also wondering how they're going to get Harold (yes, I've named that guy in the video Harold) to assist with shutting the door when the rocket is 220km agl. :lol: :lol: :lol:

I like Proline 4500 and if you have some laying around I'd recommend using it over the JB Weld. That said given the maximum speed this rocket will see you'd be more than fine with West Systems. In future you probably want to save JB Weld only for bonding motor retainers.

Anyone know what happened to Stanbridges

As many a WA resident knows if you're in Perth proper and want to visit a hobby shop that had more than just Estes kits Stanbridges was the go. I say was as it seems things have taken a turn for the worse over there. Last weekend I happened to drive by the shop on the way to the city. Historically t...

Re: What is your project for Thunda Down Under 2018?

I think you've got the right idea. However while I think I should be able to do an L3 with my current experience, I don't have the MD experience id like to do a MD L3. That's a fair call then. I had already flown MD airframes heaps of times before I did my L3. That said I'm sure you're more than ca...
