Finally got my Raspberry Pi Quadcopter stable but...

why have I had to add yaw PID gains that are much higher than I'd expected?

I would have expected that a quad hovering horizontally should require virtually 0 yaw compensation due to 2 cw and 2 acw blade putting out almost identical power.  But actual

Error compiling Arducopter trunk with modified version of the Arduino

Hi!

I have been able to build before but for some reason I deleted the IDE so I had to download it again and now I cant build. Doesn't give any error messages so I dont even know where to start.

I downloaded the modified version of the IDE and configur

Battery spark wiping out EEPROM?

Seems I am corrupting the eeprom on my APM 2.6 almost every time I connect my batteries.  I am using 6S 10Ah packs with XT60 connectors.  Every time I connect them, I get a large spark.  I am guessing this is what is corrupting the eeprom.  Should I

Losing Altitude in Loiter (ArduCopter)

Hi everyone,

I am an APM2.6 with FW 3.0.1 on my quad with T-Motor MT3520-11 Motors and 13 x 4.7 APC props.

When in Loiter mode and no operator instructions my quad sits perfectly still however as soon as I fly into the wind I lose altitude (2m loss ove

Camera triggering message through telemetry?

Hi all,

I use APM:Copter and the newer beta firmware to take advantage of geographical distance camera triggering. Did a test some days ago and it works. The downside is that this beta version seems to overburden the processor, causing telemetry messa

compensate the fall when fast throttle is applied to quadcopter.

hi all,

what's the setting to adjust to compensate the fall of the quadcopter after a fast thorttle is pushed.

it's like i want to quad to know that it's falling after a fast push up so it wont fall fastly.

Setting Failsafe turnigy 9x with frsky receiver

hi guys,

i have been trying to setup the failsafe by setting the pmw on the throttle. but when i shut down my transmitter the pmw remain the same. i think i should setup the frsky receiver right?

i was thinking maybe it's an internal failsafe in the fr

Indoor navigation using WIFI signal strength trilateration.

Hi,

i am currently looking at ways to implement a wifi based navigation system using an arduino uno in combination with a wifi shield. The shield is able to detect wifi signal strength and could possibly be used to reconstruct the position of an arduc

Settings to damp altitude corrections during a altitude-hold loiter when flying in windy conditions

The other day we were flying a QuadCopter with Version 3.1RC2 of the firmware We set a waypoint at an altitude of about 10 meters and then put the quad into indefinite loiter mode. We noticed that every so often as the wind gusted, that the quad woul

Mission Planner Geotag Tool info?

Hi,

Does the MP geotag tools tags the pitch, roll, yaw info on the picture? If not this will be a nice feature for some softwares to better process the data. 

propellers making a humming noise just pas mid throttle

So i just built a H8 copter today, as far as i know one of the fist H8's but anyways

When in a hover, if i throttle up to ascend, the props make a humming noise, similar to diving in a airplane.

like the props are oscilating besides teh rotation.

Hi Michael

I still have some 1280 APM1 boards, that I dont want to throw away  just yet, so want to use them for ArduPlane purposes.

The Previous code, 2.74, still works on the APM1 1280, but for setup purposes , I cannot use CLI for level commands, te

I'd like to set up a high speed off-road automated vehicle, and my initial concern is whether APM:Rover supports any sort of stability augmentation / ESP / traction control out of the box, or whether that's something that would require bespoke develo

Wrong Volt and Amp readings on HUD

This is a repost of Andrews previous post as he too is having similar problems. It almost looks like I have a bad reference voltage on the board. Is there a way to verify that I have a working reference voltage?

Any help would be appreciated.

Gopro Hero 3 suitable for photogrammetry with Agisoft Photoscan ?

Hi,

I know the Hero 2 is NOT suitable for photogrammetry. I just wanted to know if the Hero 3 is working for photogrammetry and if it does, how the quality of the Pictures compares to i.e. a Sony NEX 5 for typical Photoscan 3D models applications.
