I have been flying in Naza mode since my 4th flight and like the control and piece of mind it provides. However, today I noticed the S2 switch doesn't do what it is suppose to do. IOC doesn't work and neither does Home. I have my S1 switch set for Atti and Failsafe, which both function normally. Personally I guess I can live without the S2 switch working, but I really do like the home position when I am out pretty far, get disoriented, and want to bring it in a little closer quickly without putting it in Failsafe. Has anyone else had their S2 switch stop responding? Beyond a loose connection in the RC does anyone have any suggestions what might be going on or trouble shooting ideas? Thanks!
