I've gotten a lot of responses to my posting on wanting to buy the Inspire. Can any of you chime in on what to look for as I'm going to be checking a few out! Other than obvious physical damage, anyway to tell the time on the rig or battery time or damage? Any flight modes or anything I can check on the radio to tell if it's in working condition? I know it's probably less headache to just buy new; but looks to be some decent deals out there at the moment!
