Ok guys it seems there are serious problem with the control stick programing on the ST16's.. I have been told by Yuneec my st16 needs the control sticks replaced and then the repair shops get it and they say its not the sticks its a firmware problem.. 3 times.. each time it comes back and works good for a few weeks then here we go again.. This time its the forward and back stick movement... When I got it back I went out to give it a test flight and it would only creep forward and back so when I got it back on the ground I went into the Hardware Monitor and sure enough the forward and back stick gage shows the stick response moving real slow again and only going to 30% throw at full stick... I called Yuneec and after only a 30min wait I talked to a repair tech who went threw all my work orders and due to not being under warranty any longer he agreed he would send me a set of control stick units so I could replace them and at the same time have a look to see if we can figure out what's going on with the potentiometers.. I received the control sticks in 4 business days and set down today to change them out.. Before taking the transmitter apart I decided to watch a few of the YouTube videos showing how to disassemble the transmitter and also stumbled across Richard Gilmore's video showing how his K1 Pan knob some how got mixed to his J1 up and down controls.. So I went back in to the Hardware Monitor and tried moving each control and low and behold I found that when I move my J2 yaw stick left and right my J3 control gage moves real slow also.. Full left yaw J2 stick causes the J3 stick gage to move forward to 25% .. This mixing that keeps happening to everyone could be a major cause of fly aways and crashes... Like you said Richard if you had turned K1 a little farther she would have dropped out of the sky!!!!! So now the question is what can be done to stop this from happening.. Does anyone know how to turn on and off mixing in the ST16?? I will be calling Yuneec on Monday morning and will post what they say here on this thread.. If you have control stick problems we could all post on this thread and maybe we can keep track at what's going on to solve this problem....
