Clifton Hipsher replied to Jason Greening's discussion Throttle mid/hover. in the group ArduCopter User Group
"That chart still does not tell you what the thrust values are at 50% throttle, and because the physics are not linear, you cannot interpolate thrust at 50% based on thrust at 85% or 90%.  In fact, full throttle thrust is pretty much meaningless…"

Clifton Hipsher replied to Jason Greening's discussion Throttle mid/hover. in the group ArduCopter User Group
"Well, if the real wold motor data is even close to what is published here:Mars Power 2212-920Kv, the problem with the current power system is the props... To hover at 50% throttle each motor must make at least 325.25 grams of thrust. According to…"

Clifton Hipsher replied to Jason Greening's discussion Throttle mid/hover. in the group ArduCopter User Group
"Well, yes.  But more importantly MP is telling you the aircraft is under powered.  65% throttle just to hover coupled with an effective maximum throttle of 95% or so, leaves a scant 30% throttle for maintaining stability and…"

Clifton Hipsher replied to Bob Smith's discussion APM 2.8 landing gear retraction in the group ArduCopter User Group
"Yeah, what Craig said.  BUT, if you  really want automated AND manual control, get a Pixhawk.  You can use the radio to manually retract and deploy the gear and you can use LAND to deploy the gear automatically.  This works…"

"Check THR_MAX parameter.  It is supposed to be set to 1000 (100%) and I bet its set to 80 (8%)..."

Clifton Hipsher replied to babak's discussion VTOL birdseye view firefly 6y frimware pixhawk in the group PIXHAWK
"From reading the manual it looks like the FireFly is a CUSTOM system with its own firmware and ground control system software and remote controller. With that being the case, logic would suggest that you cannot use qGroundControl or the…"

"Cala wrote: "z axis is the most important not to have troubles and affects baro so, with a Lidar you solve altitude hold but no vibrations, try to solve them or you are going to be always flying near limit to crash." Would you care to…"

Clifton Hipsher replied to Anjum Shariff's discussion Follow algorithm implementation for a UAV (PX4 firmware) in the group PIXHAWK
"So what we need to find out is the OP's definition of "car."  Is he talking about a full sized passenger automobile, or is he talking about a model and a "flight controller" that is running ArduRover firmware. As for…"

Clifton Hipsher replied to Anjum Shariff's discussion Follow algorithm implementation for a UAV (PX4 firmware) in the group PIXHAWK
"You are reinventing the wheel. A Pixhawk or an APM with a GPS and telemetry radios will follow either an Android device or a laptop.  Its called "Follow Me".. http://ardupilot.org/copter/docs/ac2_followme.html"

Clifton Hipsher replied to Biswajit's discussion Facing problems while calibration in the group PIXHAWK
"A common mistake is connecting the receiver to the S.Bus port on the Pixhawk. The S.Bus port on the Pixhawk IS NOT a receiver input port.  It is actually an analog RSSI input port. Connect the receiver S.Bus output to the Pixhawk RCIN pins.…"

"The vibrations are within limits: http://ardupilot.org/copter/docs/common-measuring-vibration.html To get a better idea of the actual levels you need to review the log, and in the browser select Vibrations 3.3, right click in the graph pane and…"
