I've been using a pre-production skyBeacon for about 4 months and the unit itself has performed flawlessly. Installation is "as advertised" and only takes a few minutes in most cases. However, in my particular installation, I don't have a symmetrical wingtip and the mounting position was high relative to the center line of the wingtip and my all-metal wing seemed to partially block the skyBeacon from receiving the transponder's squawk, resulting in PAPR "baro-alt" errors. I resolved this completely by fabricating a mount to move the skyBeacon forward to clear the wingtip. This had a second benefit in that I could continue to use my nav/strobe in it's original position. (The skyBeacon I have has no strobe.) I now have 100% error-free PAPR reports!
I believe in a more conventional wingtip shape as in a C-172 or Cherokee where the nav/strobe is either on the center line of the wingtip or slightly below, the skyBeacon would do fine in it's intended mount replacing the nav/strobe. Certification is pending and they are also developing a unit with an integral strobe. For those who already have an ADS-B in solution, this would be a quick and easy installation and it doesn't require any additional antennas or cabling. Once certified, it would definitely save a lot of shop time and installation expense for those with certified production aircraft!
