    how to enable course lock?

    OK thanks, this is resolved, thanks for all your suggestions. The bit about hitting ENTER before leaving the page is news to me, I'll try that next time! Yes, CL is supported in GPS mode.

    toilet bowl effect after firmware upgrade to 4.02

    Looks like that fixed it. Maybe nothing was selected...don't know what it defaults to in that case. Regardless, I checked 'quadrotor x' per your suggestion and then took it on a 30 second flight. Smooth as silk. Thank you!

    newbie - here's my plan tell me what i'm missing...

    I'm interested in FPV flying in a tight mountain valley in central Washington State. GPS is easily available but we effectively have no southern horizon at all, so for example Iridium satellite access for phones is sketchy. No RC flying experience, and the area I will fly in is steep and...
