I saw this on the Stratux Facebook page and thought it was interesting. Apparently the new Sentry has this feature (
http://flywithsentry.com)....which is basically a Skyecho 2 with the ADSB Out removed and CO detection added. I think it would be a useful add-on if it's possible to integrate it into PAW but only offer it as a thought as I have no idea if there's space available/capacity to handle the calculations/power etc etc etc.
