Had a lot of fun playing with Symas and UDIs but got tired of losing them in the wind. I realized the $ I'd put in these would have bought a 'real' unit.
saw a Holystone HS700E on Amzon for about $300. got one.
wow. what an upgrade.
POSITIVES: flies like a dream. automatically hovers. very responsive. powerful motors (I flew low and blew leaves off the ground!). nice long battery life.
RTH functions well. handles little wind well; haven't tried in *real* wind yet.
NEGATIVES: startup is quite a ritual with buttons to press and turning the unit in circles twice (awkward with the props).
I've tried two different chips and can't get a picture.
anyone getting into quads--I'd recommend a cheap starter (like a Syma) to develop flying skills; then move up to the Holystone. very nice unit.
took it out in the public land today. long walk. used two different chips, no pix.
did research. guy on Yutube said it needs 'class 10' type TF chip. went shopping and found a couple mid-price chips that said 'class 10'. set up the unit in the kitchen without props; pressed the button and saw the camera icon so it should be good.
did not see this anywhere in the Holy Stone info.
nice open space near the water. a bit of wind. unit moved more than usual but didn't drift away.
