Hi There,
Been flying quads for last year. Mostly building my own and racing, tuning etc. Hopefully not considered a total noob.

Flying the Vendetta without issue. Swapped the cam out for Hs1177 to enhance the joy.
Problem i'm having now though is:
When I change the VTX channel via the OSD, the channel takes but when I un-plug the battery and re-power up, it's reverted to default frequency. The mw changes stick but frequency keeps reverting to default.
Any idea's?
Have reflashed dfu and hex files to FC from the powercube link. Is this an issue with powercube of core?
Any pointers would be great. I can work around it for now but some race day it'll be a pain.
Thanks in advance,
Ty
