Well, don't want to make this long drawn out post but, I recently started flying again and my alias has been acting weird as in, if you let off throttle it will just fall or at times turn upside down. I have changed to MMW motors black edition. Changed gears, shafts, replace lens, replaced some bearings, all props look fine with no cracks or bends just some scratches. Also did transmitter reset and factory reset. If you stay on throttle it will fly ok. Just, not the same as out of box. Was wondering if anybody had anymore suggestions. Thanks in advance
