Uploading software erases the bootloader on ArduIMU+ V2

I have an ArduiIMU+ V2 that seem to lose the bootloader every time I upload a sketch.
Is anyone out there experiencing the same problem?

Uploading a sketch from the Arduino IDE (v0018) gives me this error message:

  Binary sketch size: 16080 bytes (of a

Quad assembly

So I almost have my quad up and working. My quad looks almost like like Jose's quad copter part ii. It's built on the ArduPilot Mega with OilPan. I'm trying to figure out what I need to do, in order to have the left and right spin CCW. I'm using the

Will This Work On A Conventional RC Helo??

Will This system work on a RC helicopter like it does a plane??? Is it easy to install?

Thanks,

Joystick Instead Of TX To Control UAV and Camera???

Does anyone know of a joystick control that hooks to a laptop so I can control the plane or helo plus the camera?? Similar to the unit on this page (Scroll down to the laptop control): http://diydrones.com/forum/topics/705844:Topic:46265?id=705844%3A

Calibrating ESC

Quick question I am ready to cal my ESC’s again. But I do not want to blow it up again. I was thinking of unsoldering SJ1 and powering the board with usb Also I would be able to see the cal with the configurator. Then power the ESC’s and receiver wit

GPS (uBlox) Setup

I'm trying to run the Raw_GPS_tester program listed on the website, but can't get it to respond beyond "Begin GPS Test".

APMega - 1.0.1 alpha now in the repository

Jason and I have just completed a major update to the ArduPilot Mega code.  We have updated the version to 1.0.1 to reflect the change.  It is in the repository and ready for alpha testers.  Look for revision R418 or later.

The change you will most ne

BlimpDuino old Hat?

I look through this forum and I think all posts are from 2009 so i hope BlimpDuino is not old hat.  As I am new to all things 'Duino" and all of RC I have a couple of questions: How can one test a servo without hooking up to the board?

I'm pretty sure

NMEA gps with AP 2.7

I tried to use NMEA gps with AP2.7 (svn revision 1272) and run into a strange problem:if I set GPS_PROTOCOL to 0, and load resulting code into AP, then AP failed to init.In the serial monitor I can see only few first lines of the initialization outpu

hi everyone,

Weird stuff with MTek and ArduCopter.

Has anybody seen this behavior before.  When the MediaTek MT3329 is hooked up I see some sort of noise in the read outs.  Several of the indicator jump at a specific intervals. I’m able to run both the NMEA and MTK Binary test code ok and reports bac

DCM Algorithm vs Direct Integration

Hi Everyone.
I am new to this forum... long time reader, first time poster. I hope to contribute to the community.

My question is regarding the DCM algorithm:
I have simulated Bill's DCM algorithm in MatLAB/Simulink, and it seems, that direct integratio

Perfectly in the exact opposite direction to the waypoint

Hi All,

I was flying my plane today and found the following:

Stabilize was working nicely. Especially with no throttle, it would glide beautifully.

FBW_A: worked well.

FBW_B: worked well when I turned off the air speed sensor.

Auto: I had to reduce the

Some problems with servo APM

Hello, I found some problems with some units Towerpro servos used for the APM, the servos are GS-90 and MG-16, Towerpro.

The problem I found is that they go mad and out of control, both manual and any other way.

However, in other units installed in the

Ardupilot 2.7 Beta 3 out

This version includes some great bug fixes - thank you beta testers. I've included a new feature for managing altitude changes. Expect to see smooth lines between waypoints instead of the full throttle approach right after hitting a waypoint. This wa

Im not sure if this is in the right section as its to with mechanical things but is used in aerial photography and atmospheric circles.

You have your platform attached to its balloon and you release them into the heavens but you have no predetermined

Moment of Inertia

Hi,

Not sure this is the right place to post this, but has anyone calculated/estimated the moment of inertia in pitch (Iyy) of the easystar.

Thanks.

Flight modes

The Ardupilot allows you to have multiple flight modes of which I would actually only need 2 and downsizing has already been discussed but downsizing irrelevant code is not what I want/need.

Could I have two sets of autopilot code one setup for fast

Arducopter Startup

Hello,

Yesterday I setup my quadcopter electronics without frame. My setup is:

• ArduPilot Mega

• IMU Shield (Oil Pan)

• KDA 20-22L brushless motors

• Electrifly 35A Brushless Electronic Speed Controls

• Futaba 6EXP 6 Channel FM Tranmitter/Receiver
