Folks,I narrowly avoided a flyaway with my newly finished Flame Wheel 550 with an APM2.5.  From what I've determined so far, the issue seems to be related to mounting the APM between the top and…Continue

What causes an APM 2.5 to save the home location?  Power up when GPS locks, or arming?I'd really like it to remember the home location when I arm it...Thanks for the information.Continue

Optimum ArduCopter motor shaft to motor shaft distance?

First, what is the span or distance from motor shaft to motor shaft on the shipping ArduCopter? Second, is it better for stability to reduce the span, or increase the span. I understand that yaw…Continue

"I won't debate you, but we can't win this fighting it as individuals.  We need the resources and leverage of the AMA to carve out a niche where we can enjoy our hobby.  My statement about a quad over an active runway may seem…"

"Everyone is free to file their own comments, but if folks are stupid about it, it will do us no good.  Clearly at this time we need to support the AMA, who is trying to support us. If we make make "in your face" comments to the FAA…"

"So you have a problem with the FAA trying to stop someone from flying a quad over an active runway at an airport because it's out of their jurisdiction?  You might feel different if you were on that aircraft. If we play by our own rules,…"

"So... if you have some of the nose of the aircraft visible in the FPV camera, then as the operator, you can see the aircraft all the time...  :-)"

"Hi All, I'm having the same problems with even more compiler errors.. I have checked the path... and it does contain the AP libraries.. There must be another issue??? Any other idea?? "

"Hi Bill, all, Hope you are yet following this thread, I have rather similar issue, receiving same set of errors, and HAL setting did not fix it, yet I get errors starting from the following type of errors; In file included from…"

Bill Sanford replied to Randy's discussion ArduCopter-3.0.1 released!
"Agreed.  Every issue I've has has been my own doing.  There is a steep learning curve and knowledge is required to set these up properly.  The flight controller and software is very stable and works well.  IMHO, I think that…"

"Hi Rick, Great points.  I need to run some more tests to be 100% sure, but I'd bet money this is what is happening.  When I had the issue, there was a pretty strong headwind and I had a long upwind leg in the mission plan. When…"

Bill Sanford replied to Randy's discussion ArduCopter-3.0.1 released!
"Yes, I already slowed it down a bit in auto mode.  This certainly helps.  The fact that speed takes priority over altitude in the flight control software seems backwards.  That said, the 3.0.1 software is AMAZING and works very…"

Bill Sanford replied to Randy's discussion ArduCopter-3.0.1 released!
"The reason I want to set this is because when flying in auto mode, if it's windy, when flying into a headwind, the copter will lose altitude and crash because it tips so far into the wind that it doesn't have enough lift to maintain…"

"How can I set the maximum angle the copter will tip when it's flying in auto mode? Is there a parameter for this?"
