Re: Rocket tracker & monitoring thing

Nice work strud. Increasing Tx power on the bird will not gain you much extra range without significant power increase. You need a 6dB increase in power to double your range. A 3dB increase (double power) will increase your range by 41%. You are fare more likely to improve your link by a better grou...

Re: Derek's Level 2 Build

I just use a bit of recovery wadding (crepe paper party streamers from a reputable supplier, for fire retardancy) and the cap that comes with the centrifuge tube. Do your tubes come with caps? You could also use a layer of Kapton tape over the top. I am sure masking tape would suffice too. Another a...

Re: Rocket tracker & monitoring thing

Nice progress.

Anyway, there is only 1 cut track and 2 wires...

That's a good outcome for a first revision PCA.

Re: Battery isolator

Don't forget if there is any risk of the phono plug shorting anything out you could machine up a piece of plastic, like nylon or something, and use that. If you want low-tech I think 1/4" dowel is "made to fit" perfectly. That's what 1/4" phone plugs are about :D

My L2 rocket (also flies on L1 motors) is the Binder Design Velociraptor. These have a cardboard airframe.

Re: T-Bolt Rocket Kit vs Super DX3 L1 Certification Kit

Welcome Stefan, As others have said, fiberglass is not a requirement at those levels but can make for a more robust rocket. You can certify both levels with the one rocket but I would recommend maybe building two, just to add another to your fleet! It also adds a little more experience. Keeping thin...

Re: Electronic flight cards

Call me a Luddite if you want, but paper sounds like a great way to do this. Technology needs to be designed, implemented and maintained.

Re: GPS, APRS, and serial (or how I came to realise that redundancy and data are both good things)

That FT3DR looks seriously neat. If I were not spending so much on upgrading my 4WD currently I would spring for one of them instantly. Maybe I can get one as a Christmas present to myself! Having redundancy on Rx is a nice feeling. I have been doing that for my past couple of flights, but with dual...

Re: What’s everybody up to during the lockdown?

Not sure yet, maybe a H225. I’m a bit concerned about the stability and may need to add some nose weight. PML claim it should fly as is, but OpenRocket is telling me otherwise.

Do a swing test :)
