Hi all my 450 naza arms the motors as per normal start up ie both corners of sticks after powering up on landing the motors are still spinning at quite a rate but not enough to lift up. Tonight after landing life in my hands just about got her up and unpluged the batterys which are on a Y leads. Is It as simply as triming back on the throtle trim but it was getting dark other than that Is It a set up problem.:upset:
