Taking pictures continously

Hi
Don't know much about photographing and need some help with chdk. My camera is digital ixus750 and I want to use that to take pictures continously from radio-controlled airplane. Altitude could be something like 50-100 meters.
It could take pictures let's say every 2 seconds. How do I set it up...?

Just instal one of the intervalometer scripts from http://chdk.wikia.com/wiki/UBASIC/Scripts#Intervalometer in the CHDK/SCRIPTS folder on the card and start it just before you launch the plane.

Thanks a lot zeno! Interval seems to be 5 seconds in script but it is not. When I start script, camera takes one picture. I waited couple minutes but no more pictures. How do I change interval to 2 sec?

You didn't say which script you loaded, but you need to check the parameters - one of them will set the interval between shots and another will set the otal number of shots.  To do this:

1. go into <alt> mode (by pressing the print button)
2. select "scripting parameters"
    You should now see a menu which has "Load script from file ..." at the top
    scroll down the menu and below the dotted line you'll see a set of lines describing the parameters
3. select the one that sets the interval and use the left and right buttons to choose the interval you want
4. do the same with the "number of shots" parameter

Note that your camera may not be able to take shots as rapidly as every two seconds, particularly if you have
not set the Canon "Review" option "Off".

camera takes one picture.
On some of the IXUS / SD series cameras the shoot command may not work correctly,
the "Ixus shoot issue" - read more here: http://chdk.wikia.com/wiki/Talk%3AUBASIC/Scripts%3A_Ultra_Intervalometer#SD550_Intervalometer_not_working & here: http://chdk.setepontos.com/index.php/topic,2380.new.html)

I suggest either to replace shoot with click "shoot_full" (maybe also additional sleep & release commands are needed) in your script,
or simply use one of the following Lua scripts:
* http://chdk.wikia.com/wiki/LUA#Minimalistic_Intervalometer (minimalistic)
* http://chdk.wikia.com/wiki/LUA#yet_another_accurate_intervalometer (another one...)
* http://chdk.wikia.com/wiki/User:Fe50#double_intervalometer (double intervalometer)
* http://chdk.wikia.com/wiki/User:Fe50#fast_shooter (my fast shooter, for max. speed)

The script parameters (shooting interval etc.) can be adjusted like zeno described...

Don't forget to set the duration for your needs, the default value is only 20 seconds ;)
...also i suggest to set fix focus to infinity, maybe also a short, fix shutter speed etc.

Good luck !
