My fellow colleague vision 2 pilot, pointed out to me, that the props are designed for the vision one.. They are shorter than the standard for vision 2.. Perhaps this is what's causing the vibratory problems.. I've ordered a set of new props, unfortunately, they're on back order.. God only knows if and when I'm ever going to be able to fly my copter.. I even got a message from Jason today, from DJI, saying I have to phone their service dept. before I can ship the unit back to them.. --- Even though his March e-mail to me said to ship it back to them in Hollywood.. Now it's like they're trying to create hoops for me to jump through.. Jesus, I would have shipped it back, had they not been so late in responding to my concerns.. As it was I got in touch with my dealer: multirotorheli in Calgary, who told me to send it to him.. He kept it for more than a month, and ultimately made the problem worse.. AAR, I've also ordered a couple of motors, just to be on the safe side, if the proper blades don't solve the problem.. Jesus, I've spent over 1/3 the cost of the copter, and it's still not working right.. It's too bad.. Overall I think DJI has a great product, and would have bought the vision+ in a heartbeat, if the service I've received so far for my vision2 wasn't so crappy..
