Could it be the transmitter ?
I tried 5 to 8 channels
5 is "selection mode"
6 is " pitch control "
7 is free, but can be activated ( just as an on / off control )
As for 8, I do not understand how it works ( 8 on the transmitter seems to be an " on / off " switch ? )
Sorry for asking so many questions, ( and for my English style )
ps: I purchased and received my iris on March 2014 … but only achieved my first flight 2 months ago …
… and enjoyed it - Worked perfectly.
Curtis who posts often on the 3DR IRIS users Facebook page has the FY-G3 Ultra on his IRIS, he’s just tweaking and seeing if it’s suitable at the moment.
