SpaceX Falcon 9 and Fairing Flying Model Rocket Kit

SpaceX Falcon 9 and Fairing Flying Model Rocket Kit Got a mate of mine to bring back some stuff from the SpaceX shop when he was visiting the USA recently. As part of the batch I got two of the Falcon 9 plus Fairing rocket kits. Cost was $29USD each: kit.jpg Assembly was simple, and probably a bit ...

Re: Screw Switches

D2HW-C212MR.jpg https://www.digikey.com/products/en?keywords=SW727-ND There are a couple of different variants, depending on whether you want the wires out the side or the bottom. Make sure you get one that has access to NC (normally closed) contacts for the pull-pin use. Some of the two-wire varia...

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. Something like this: AltsCompleted.JPG sledtop.JPG Details on the entire build here if you are interested: https://forum.ausroc...

Re: Screw Switches

I've gone to a pull pin setup now with micro switches, really minimizes the complexity and stress at the pad.


Tried a few things, and the pull-pins are my preferred method. Just so simple and easy to not forget.

Re: Hardware Choices?

So does it use a minimum of 20 hopping frequencies? The EggFinder is not FHSS. If it were it would fit under item 56 in Schedule 1 of the LIPD, assuming it used more that 20 frequencies. As stated, it fits in item 58 of Schedule 1. Does not need to hop. Refer to my earlier post for results. There i...

Re: Hardware Choices?

Some basic test gear is coming out at amazing prices these days. Specialist items now are trending towards commodities. I'll stick with the CXA. Not quite DC to daylight but 9kHz-13.6GHz is good enough, especially considering it is well optioned (I made sure of that :wink: ). Ours is used for intern...

Re: Hardware Choices?

Don't need to have other firmware to launch overseas. Just need to make sure you are on the correct frequency in the country you are using it in. I was doing some ground testing on the TRS whilst in Singapore recently. I made sure I complied with their requirements whilst I was on their territory. N...

Re: Hardware Choices?

I must stress this. Make sure you have the correct firmware loaded It does not necessarily need to be the correct firmware. Even with the incorrect firmware loaded there would be no problems using the system if the frequency selected puts your system within our ISM band . The class licence states 9...

Pretty sure those Pistons gave you an extra 50 feet on the nose cone.

Yep. Sure did. With an apogee of 624' we needed all the help we could get :)
