2.4.1 is actually smaller than 2.3. It should fit into a 1280 if you explicitly define the GPS type.

In APM_Config.h make sure these lines are included:

#define FRAME_CONFIG HELI_FRAME

#define GPS_PROTOCOL GPS_PROTOCOL_MTK16 (or #define GPS_PROTOCOL GPS_PROTOCOL_UBLOX depending which GPS you have).

Arduino tells me Binary sketch size: 126714 (of a 126976 byte maximum).

The error you have seems to indicate that your folders aren't set right.

It should be set up like this:

C:\...pathname to whereever\sketchbook folder

within that make sure you have:

C:\...pathname to whereever\sketchbook folder\arducopter

C:\...pathname to whereever\sketchbook folder\libraries

The short answer to your real question about installing old version with mission planner, is no, you cannot.

Are you using the Arduino relaxpatch version?  Do you have the APM libraries copied into the arduino libraries folder?

@Robert, yes I'm using Arduino-0100-relax, running on windows XP SP2. I followed the exact procedure suggested by Don, and tried also to put APM "libraries" into Arduino libraries folder, but nothing. Anyway I succesfully uploaded the 2.4 version of Arducopter on my board, using mission planner, but it's very important for me to manage the code since I have a 90° swashplate on my test helicopter, so I have to upload "manually" my modifications.

I apologize for my "stupid" question...but I'm a Finite Element aerospace Engineer and it's the first time I play with this stuff...morevoer if you suggest me a "dummy proof" tutorial to understand more in detail Arduino I will appreciate it very much :-)

Thanks to all!

Ok, here's a "for dummies guide" ;)

1)Download this:

http://code.google.com/p/ardupilot-mega/downloads/detail?name=ardui...

2) Unzip it

3) Download this:

http://code.google.com/p/ardupilot-mega/downloads/detail?name=Missi...

4) Unzip it.

5) Put both of those into a directory somewhere.

6) Go into the Libraries folder of the Arduino folder, and delete everything except the SPI library folder.

7) Go into the Arducopter/libraries folder, and copy all of the library folders, and paste them into the Arduino/libraries folder.  Make sure the SPI is still there.

8) Load up Arduino, set your sketchbook folder, Open up Arducopter.pde. Go into APM_Config and set that up.

9) Compile.

This should work.  If it doesn't let me know.  I've struggled with it before, and it's always the libraries that trip me up.  For some reason over-writing the libraries doens't work.  You have to delete them, and copy the new ones in, but you have to keep SPI.  I don't know why.

Ferruccio, do you have a workable program for the swashplate?  Are you talking about H1, or a 90° CCPM?

Robert, THANKS a lot! Now Arduino is running well!! My test helicopter has a 2 servo swashplate (H1), so collective, roll and pitch are decoupled each other. I currently have some ideas on how the code should be modified in order to configure this (old) kind of swashplate, so let's try... :-)

Do you have Skype?  We should talk.

Try downloading this and giving it a shot!

I don't have an H1 to test it on!

Hi Robert, I will try it ASAP... and keep you informed how it does work! Thanks a lot

Oh, I have to tell you, don't install my current clone.  It got broken on the weekend when I merged the latest trunk back into it.
