Hello, I'm looking for a little help. I just posted this on wattflyer but I feel this may be a better forum.

My son and I received a pair of micro helis for Christmas. His CX takes off well and settles into a nice hover within seconds. My FP on the otherhand starts to get light on the skids and shoots left like crazy. I figured it was just ground effect but getting a couple of feet under it doesn't seem to change anything. Any thoughts or is this just a newbie problem I'll need to overcome?
