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.

Mission planner CLI wont talk to AP 2.74

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

Off-road racing with APM:Rover

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.

90 Degree, 4-servo CCPM

I'm working on altering some elements of the Arducopter code to add support for 4-servo, 90 degree CCPM and could use some help from developers with experience with the code base.

It seems that the only files that need changing are in AP_MotorsHeli (.

Metrics for Arducopter Stability

Hello All,

In my research project I am asked to specify with metrics for platform performance i.e. 'how good' is the platform that I am using as compared to other platforms available in the market (APM:Copter, AR.Drone, HK KK, MicroKopter, etc), in te

Aux channels on APM 2.5

Hi,

I've got an APM 2.5 with the latest x8 firmware.

I'm using a ppm receiver. I'd like to control a servo from one of the auxiliary output with a PWM signal.

Is it possible to do this (map one of the ppm inputs to a pwm output on the apm?)

Thanks

Quadcopter Build assistance

Hi guys, ive been told off by some rather cocky arrogant people on this site for asking some simple questions not too long ago!

Basically I want to build my own quad, something that if I crash I can easily repair it. Then I was told I should buy a R

Is bigger better?

Say you wanted to build a glider to do the usual glider things. How big would you make it?

Given that fuel load is not an issue, and the mass of the APM is insignificant, would you make the wingspan 1.5 meters or 3.5 meters? Or bigger than full size?
