Purchased this for my grandson for Christmas. Hasn't flown a single time. It's communicating, and starting up but when I press forward to life off it surges forward and flips over before it gets air born. Tried all the manual recommendations, re-calibrating, etc. Nothing seems to help. The only thing it's good for is display shelf duty. Can someone help me please???? Tried to post a video but too big I suppose. I've looked high and low for a place to post a question to Syma, but I suppose they don't feel the need to have support.
