I built a quad with Xproheli XPX frame. I used all of the recommended parts, motors blades etc. Tiger Motor MN4012 480kv Navigator Series, 14" APC props Naza m V2. I've tried recommended gain settings and experimented with others. The quad wobbles bad on descent and in wind. Way more than any other multirotor I've had. Xpro tells me it's how they are. Doesn't seem right to me. Any ideas or thoughts would be appreciated.
