Questions about circle and loiter mode

Hi,

as I understand, circle is supposed to be like loiter, just without GPS. Last weekend, I was out testing and switched my APM into cirlce mode (with the R/C) and nothing happened. The Bixler 2 just flew straight. At this time, no GPS was installed to the APM which is running Arduplane 2.7.

Am I missing something? Shouldn't the plane have started circling?

Then about loiter: I suppose, when I switch the mode to loiter via the R/C, the radius is WP_LOITER_RAD, right? Or is there a different setting? How about the altitude? Does it loiter at the altitude where it was when I activated altitude (aka ALT HOLD) or does it go to any preconfigured altitude? Same question goes for circle...

  • BTT: Which parameter sets the radius for  circle? Does it use the radius setting from loiter?

    I'm not an arduplane expert but i think that both circle and loiter on arduplane will default to attempting to hold the current altitude.

    I would have expected the plane to start circling instead of just going straight...
