Mission Planner Circle Tool Center

The Auto WP circle tool in MP is awesome, but how do you determine where the center will be? It seems to go off generally in a NE direction for a random distance and then draws. Is there a rule?Continue

John Hanson posted a discussionWARNING -- DANGER -- FOLOW ME MODE TESTING
I recently posted my test of follow me, and it ended very poorly - basically, after trying to get out of follow me mode it just hovered and eventually fell like a rock.I have been testing for over 2 yrs now but this is the first time among countless versions and crashes that it ever just hung 100' right over my head (very unnerving!) and I had no control at all. In the past any bad situation could be recovered by flipping to stabilize, but not here. There was no autorotation and it smashed…See More
12-HAK replied to John Hanson's discussion Follow Me Problem"I also found a similar issue when I tested it. Its very clunky switching between the GS and the transmitter. Luckily I got the throttle back up and recovered."

Inspired by Marco, I just tried 'follow me' mode, with latest Andropilot and 2.91b.First I loitered (very smooth) and then flipped to 'follow me' on andropilot. Like magic it started following me, but kept rising. I flipped to stabilize and was able to come down.I foolishly tried it again and it started rising so I went to stab, and had no throttle control, it just loitered. I turned off follow me and it just sat there. I then switch modes, and it stopped and fell like a rock. I got a little…See More
John Hanson replied to MarvinS's discussion APM2.5+ Gone"I have lost 3 Night Vapors - they are incredibly fun to take up way high when there is no wind, but you hit a layer and off it goes. They look incredible on a windless starry night."
John Hanson replied to Randy's discussion ArduCopter 2.9 released"thanks Randy! I was used to keeping the throttle at the top of the dead band in previous versions and now I am getting used to Lowering it a bit. Altitude hold is hanging in very good.

John Hanson replied to Randy's discussion ArduCopter 2.9 released"So far seems stable - the only prob I have is under sonar, alt hold works fine the first time it engages, but then as the flight goes on it starts to rise in spurts and keeps going up. Sometimes if I disarm and rearm it settles down but then starts…"

"When the Circle mode triggers it sets the current location to the center and starts North. In a mission it uses the WP as the center.

Excitng First ArduCopter Mega Mission!
Posted on May 18, 2011 at 11:04am 2 Comments 0 Likes
I finally got up the courage to try a mission with 2.05. I set up a very simple mission - takoff to 10 meters, loiter time 60, land. All the coords were very close to each other so it should land about where it took off. The first two times I started the mission, it went up a few feet and then bounced around the ground like it was at altitude and loitering. The third time was very different - Up it went very high - seemed like more like 100' rather than 10 meters - and I was sweating bullets.… Continue

Hi John,
I know this might seem random. But I just got a quadcopter myself and live in Denver. I am having some issues getting mine to take off properly and was hopping you might be able to help me out. This is why I made the friend request.
