I've no personal knowledge of the following kickstarter. It could be totally legit, self-delusional vaporware, or a deliberate money-extraction-scheme. It promises some subset of ADS functionality at a very low price point and may therefore be of interest.

I'd guess that you'd want to use it with an Iphone in a glider not an Ipad Mini.

And just becasue I can't resist... this is a UAT only receiver. It won't see 1909ES Out equipped aircraft directly. If your aircraft is equiiped with the correct/compliant ADS-B Out and it is correctly fofigured to dvertise you have this receiver and you are in range of the FAA ground infrastrucure then you should recive ADS-R services that allow this receiver to see 1090ES Out equipped aircraft. The exact same applies to TABS (since it is a version of 1090ES and does not transmit on UAT frequencies) should TABS be adopted in regulation in the USA and in particular for gliders.

Bottom line on this is there are excellent low cost and well proven portable general aviation ADS-B receivers from Stratus and Garmin (GDL-39 series). All these products are dual-band, i.e. driectly recve ADS-B from 1090ES Out and UAT Out equipped aircraft, do not rely on ADS-R at all, will recive both out side FAA ground station range, and imprtnatly will receive both revgarless of wether your own aidcraft has ADS-B Out or not. This Bad-Elf product just sucks, there is no excust for a USA manufatuer to be developigng an ADS-N revciver today that is not dual-band/link layer. It makes no sense, and with any silgle link layer receiver the reuqirmnts to fully paricate int he ADS-B srvicesd are likely too confusing/diffiuclt for the market/many owners/piots to undertsand and configure correctly (anybody want to tell me how they can change the capavility code bits cnfiuguration on their ADS-B Out system when they mount this reciver in their aircraft?... ah no I thought not.

And in glider land in the USA, we have for better or worse, and I think for the *much* better significant PowerFLARM adoption.
PowerFLARM does receive 1090ES directly but not UAT and is not compatible with ADS-R . In an ideal world PowerFLARM would be also be a dual-link receiver, but it's ancestry is from Europe and I suspec tthe complexity of baking a cusotm system just for the USA glider market means that would never happen.

Did somebody recently suggest not over worrying about all this stuff and just waiting and seeing what happens? Ah yes I did :-)
