The only complaint I have with the Ifly700 is sunlight readable. Happens I need to put it on the dash and with a full greenhouse on the L16 there's a lot of 'sunlight'. Not supposed to be a problem with the 720. I still have most of the features of the 720: alerts, terrain, etc. Chris: a friend of mine just bought a four place Bearhawk kit with a 540 (I think) engine. We're located at the Strum airport (3WN9) not that far from you and you might fly over some Saturday morning if you want to socialize and maybe talk to the owner of the kit. Sharp young man and he'll get it done.
