I recently bought the Walkera Dragonfly #4 as a cheap way to get into the hobby. I had it on the kitchen tile floor and when I increase the throttle is slides to the left. Why does it do this? Then when I get it a foot in the air it travels to the right. I have been practicing on the clearview simulator but that simulator does not do this. Actually it seems fairly easy to take off and land helicopters. I was thinking about getting the Reflex XTR. Their web site shows a Walkera 34/35 connector. Does anybody know if this will work with my 4 channel #4 dragonfly helicopter? Thanks for any help.
