X-3D Funpilot :

Hi there.

Here is my Funpilote based copter, so few thins home made here.




This is not a Arducopter plateform, butI like it. Mostly because this is real pilot stuff. Here are the features:

  • 376g without battery nor Gopro
  • The protective hull is from a Gaui

Hi there .

I just tried to connect to My APM2 usin APM planner 1.1.48 and connection failed every time.


Then I try connect in Terminal but cannot enter CLI mode, the board is initializing and then send all MAVLink info on the serial, but cannot enter C

Configuraing Elevon Mixing on APM2


I have a Multiplex Xeno, and I succesfully  confugured Manual Mode (Radio elevon mixing), and the Stabilize mode respond correctly to pitch/roll perturbation (Elevon configuration in APM mission planer).

But the elevon input mixing changes betwe

Arduplane Mode


I am looking into Arduplane Mode, and I noticed one mode might be missing: Manual&Filtered.

Several product exist to stabilize RC planes suche as the FY30A RC Gyro. I think it should be "just" a PID filter between inputs and outputs for Roll&Pit

Log & Debug info


Last time I flew I noticed the PPM led stoped blinking 1 second. so I detected that the connector was faulty.

In the log I can See the GPS fix so tere are several things that I would like to be able to check in the log:

  • PPM signal "quality" or "a

Language in APM planner

Hello all.

I recently notice that APM planner was translated in foreign language.

But it is hard for me to ave the interface in french, because i am used to Roll Pitch, throttle....

Is there a way to force the interface language to english ?

The french part of the message says: "Offset and length were out of bound for this array or the number is bigger than the element numbers of t

PID Rate computation

I am wondering why rate PID is computed like this in STABILIZE mode

get_stabilize_roll(long target_angle)

   // Rate P:
    error         = rate - (long)(degrees(omega.x) * 100.0);
    rate         = g.pi_rate_roll.get_pi(error, G_Dt);


but like thi

Motor Arming: should start turning

Hi I just experienced a situation which probably happened to most pilot, I land my copter, someone talk to me and I forgot to unarme the motors.

Then when I went to check the copter I accidently push a little the throttle. Nothing bad happen, but I re

Stabilisation methode


I have a Arducopter integrated in a Gaui 500x (900g) and before I had a X-Ufo (500g)

As far as I understood, the first PI stabilisation loop, which is the only one used for ACRO mode should be the fastest and more responsive loop.

So far the most st

Ardu copter In Gaui 500x frame


I integrated arducopter in a gaui 500x frame see the photo attached. It has :

  • 4 980 kV motors
  • 4 )18Amps ESC. integrated into the arms (the oones selling by Gaui for the 500x )
  • I use firmware 2.0.45
  • The Setting are the followings:

Cannot do loop...


I was wondering why The arducopter could not do loops in ACRO mode?

When I try , The copter don't bend more than 80° and I must abord the loop and recover from this situation.

Current ArduCopter2.0.39b PID Settings


Here are some statement I think are correct, the parameter name are from the APM planner V1.0.63, and the arducopter code from ArduCopter2.0.39b

  • Derivative term of all PIDs is now always set to 0
  • Parameters RATE_###_P, RATE_###_I: only impact ALL

Motor LEDs Behaviours

Hi, I had a look at the codeof update_motor_leds(void), and I think it might be usefull to code some logic in order to have visual signification from these motor LEDs.

I will try this, which test Motor arming ang GPS lock. I have a quad in X configura

Ardu copter first flight


My Name is Sylvain. I had a x-UFO for few years and it was a master piece of stability in ACCRO mode.

Now I integrated aarducopter in a gaui 500x frame see the photo attached. It has :

  • 4 980 kV motors
  • 4 hobbywings 18Amps ESC

So I installed 2.0.39 c
