Ryan replied to Dimitris Tripakis's discussion Are the Pixhawk or APM or other auto-pilots fully programmable ?
"Be advised, it won't be as simple as just changing the P parameter in the PID controller. There are values that are stable and those that are unstable. Also, having zero correction means it won't hold it position at all without input from a pilot.…"

Ryan replied to Manny Martinez's discussion Looking for a AGILE 1000mm Quadcopter build
"If the only reason you want it big is for a target, the quad doesn't have to be built that big, just has to look that big. Large arms to support the motors are much heavier that a stick to hold a sensor. You could also probably make it…"

Hi all,I am curious about the option in the mission planner to "Point Camera Here" (Right click on the map under flight data). I am assuming that it will, using your gimbal, point the camera at the specified point in space regardless of the…

Ryan replied to Markus Horeld's discussion APM 2.5 says: No dataflash inserted
"I'm, having this problem as well. Has anyone contacted 3DR about this?
The problem is that I'm having trouble with my APM consistently climbing when in loiter regardless of throttle input but I can't really diagnose it without logs."

I am interested in adding a video link to my multirotor. In looking at the frequencies available it seems that 900MHz seems to work the best. Best range/watt and does not get blocked easily. However, I would like to keep my telemetry link 915MHz…

Hi all,I recently bought and built a y6. All seems to be working well except in auto mode. After it reaches each waypoint, it turns towards the next and loses a lot of altitude. It ends up gaining it back on its way to the next waypoint only to lose…

Ryan replied to Ryan's discussion Fixing a Damaged Chip
"I eventually got the chip soldered back on, and the multimeter is giving a solid 3.3v (no O-scope). I can get stabilize mode working but only with USB connected. I read the excerpt in the troubleshooting guide about this problem but it worked before…"

I had the unfortunate circumstance of crashing my APM head first into the ground. Upon testing the board, everything seemed to work from the CLI but it would not work (No Mavlink, no stabilize mode) in flight mode. When  I looked closer at the IMU,…

"Does anybody have an idea of the range you get with this compared to the standard receiver setup?"

Ryan replied to Michael Foersterling's discussion Gyro/DIP problem
"Try switching the servo leads. That is, plug the left servo where the right one is on the APM and vice versa."

Ryan replied to karl m's discussion IMU Gyro Problem.
"I am having the EXACT same problem. The funny thing is, is that I had a successful flight (I was able to use stabilize mode), then I uploaded some way points to try out the autopilot function when the aforementioned began. Now I can't even get it to…"
