I have purchased the 4k but stalling pickup to 1st week in Jan. Still practicing with the Syma X5C to get ready for the big guy. I've been reading the manuals online and looking at as many vids as I can to increase my knowledge. Here are some general questions that maybe you can help me with. 1. Should I do compass calibration before every session? 2.Should I charge the remote after every session as well as the batteries? 3.I know it was said in another thread but I still don't understand why you can't shoot vid and stills in the same flight when shooting 1080 60fps. 4.Here's the biggy....landing! How are most of you handling the landings. I've seen vids of normal, cutting engines an inch or 2 above the landing area and last but not least, THE CATCH! Also what surfaces do you find best to land on? Any help would be most appreciated.
