I purchased a used dx6i that looks almost new for only $85 shipped! It didn't have the datecode sticker anywhere, but I did the test for it. It seems to have a little jump in the throttle stick when it is at idle. It doesn't do it constantly or every time but you can see the monitor move a little without input. It works fine on both my blade cx2 and pz corsair, and all the other sticks seemed to be perfect. Should I send it in anyway?
