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

cannot connect any more to my APM2 board

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

Hello,

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

Hello,

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

Hello,

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:

direct feed of PPM sum signal into APM1

Hello.

Does any one already succesfully feed the APM1 with the PPM Sum Signal? It would save space, connectors and potential failure?

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 ?

I updated APM planner to 1.0.87, and now when I try to connect to my board I got the following message

PID parameter not exactly the same when Loading from a file or the copter

First problem, write or read parameter in the board:

I am using APM 1.0.84. noticed that when I set parameters (PID rate for example), then I fly, then I whant to modify them a little bit,.

I do not get the parameter I set in the copter , for example

troubles with 2.4GHz receiver and calibration

Hello, So far I used a 41Mhz receiver and I had no troubles. I use 2.0.49 firmware

I noticed that when I forgot to calibrate the radio channels, on startup all motors were beeping.

I got a 2.4Ghz for ma Radio (Futaba FF8: T8UHP), I calibrated the chan

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);

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

Hi,

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

4 )18Amps ESC. integrated into the arms (the oones selling by Gaui for the 500x )
I use firmware 2.0.45

Cannot do loop...

Hello,

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

Hello.

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

ArduPilot Mega board dimensions

Hello,

I wonder where can I foundthe ArduPilot Mega ATMega2560 board PCB design (Dimension)
