Yes, I've tested both the Clarity and the iLevil, early production units. Both ADS-B units are functioning on the iFly 720. Weather, Traffic and AHRS. The Clarity is a smaller unit than the iLevil.
The iLevil has weather, traffic and AHRS, but has an external antenna so you will have the option to connect a wired remote antenna, it comes with a standard 4" antenna. Something else that is cool about the iLevil, is that it has a Solar trickle charger, so if continually is trying to recharge. It's also several hundred dollars less than the Clarity SV.
Both are great units. We had to send our Clarity SV back for a software upgrade, should be back in a week. I think you'll be happy with either.
