Hello group, happy Friday! I am posting this message today out of frustration in getting my Eachine250 in proper working order. I am experience in RC model racing however this is my first racing quality quad that I have owned and I am having trouble going through all the settings on Libre Pilot. I seem to be able to go through all of the calibrations and things without incident, however I just can't seem to get the controller to connect to the quad to control it. I have gone through all of the controller settings, confirmed that none of the controls are inverted....etc. But I am not able to "save" and finalize that section. The controller I have is the "Eachine i6". Is there some kind of instructional video I can follow from start to finish with this controller so I can properly set this up? I'm surprised I am having this many challenges but this is somewhat new to me. I consider myself to be handy and know my way around a PC, however I must be missing something in the process. I would even be fully willing to pay someone to do a virtual desktop session with me to help me set this up if it comes down to it. I sincerely thank the group for any help that can be extended. Have a wonderful weekend!
