For the past couple of months, I've been helping a friend with his APM 2.5 and APM 2.0 equipped octos and hexas and we haven't had success with getting rid of the often fatal motor hiccups on both the 2 and 2.5 boards. With some bench testin
My APM2 works fine connecting to windows and linux systems. I can read and write data to the serial port just fine. But, when I connect it to a machine running Mac OS X 10.6 or 10.8, it doesn't work properly.The Arduino Mega 2560 device appears, and
I was flying my 3DR hexacopter for the second time today. All went fine, loiter, circle, stabilize, alt hold etc. After 10 minutes I was loitering at 1-2 meters (3-6 feet) when all of a sudden the copter took off at 9-10 m/sec and cartwheeled i
I have read many posts about safety which I definitely agree and many posts with flights near, over top and around people and buildings.The recent post about the "pilot" hitting the building and crash burn brings to the question what is a pilot?I'm n
Hi, I want to assembly my own quadcopter and I have been seeing which parts are the better for my requirements but I don't know which battery I should use. I have seen the next
My team has a bone stock 3DR Quad-C with APM 2.5. We have successfully flown it after assembly but have recently had brownout problems and gyro problems. While hovering 3 or 4 feet, the motors suddenly die out and it falls flat hard.
My Futaba has a reduced power output function intended for range checks.
On a regular copter/airplane this would be simple, just keep walking backwards wiggling the sticks an make note when the rudder movements cease or become erratic. Since my hexac
Hi I have a question, if I buy the motor AC2836-358, 880Kv, what kind of ESC do I have to buy, the ESC 20 Amp or the ESC 30 Amp, why and why not the other?
I used Mission Planner to plan simple waypoints missions. But it was a problem to use CONDITION_CHANGE_ALT command. I couldn't set the Rate (1st parameter) more than 80 cm/sec. Also the Alt parameter (the last one) wasn't stored (or transfered) to AP
Can anyone tell me or point me in the right direction if it is possible to programe the apm 2.5 to trigger a camera when it reaches a waypoint, i currently trigger the camera from my transmitter through the receiver but would like to autom
I'm using 2.7.3 and noticed a strange behavior in RTL. If you engage RTL and then when it gets near try to push it away or hold it from arriving, it will continue trying to come home and you have to use more forward pitch to resist it. Then when you
I am adding an attopilot sensor connected to an APM1 board. The wiki seems to say I don't need to add a resistor to the board, but without one I am measuring 4.5 v on a battery with 12.5v. I am not sure if this is the cause. Any thoughts would be g
I'm selling my fully tested and flying 3DR Arducopter with 850 motors and standard ESC's. I will be removing my Rx & APM2 for my ArduPlane project. Just replace those with yours and you're flying. Never crashed, perfect shape and has GoPro mount o
I'm still trying to get the basic concepts into my head. What I can't really wrap my head around is the endurance, or better, which factors influence the endurance how?
Of course, it's clear that weight is a factor and battery capacity. Then probably,
