Your LED status seems to be normal for the USB mode (see http://wiki.bitcraze.se/projects:crazyflie:userguide:index for a list). There might be something wrong with your 4th motor, but that should not prevent you from testing the sensors etc. With "powering on" you mean that you gently pre...

Do the LEDs blink if you plug it in or light up steadily? Do the motors spin at all after you plug the usb in? Where did you buy the crazyflie?

This is really strange. You can try to see if it works with a custom pygame joystick script. For example the one here: http://yameb.blogspot.com/2013/01/gamep ... ython.html. Just a step to figure out if it is an issue with the bitcraze client or not.

You can try to switch to the pygame backend. For that, open crazyflie-clients-python/lib/cfclient/utils/joystick/__init__.py and remove/comment out lines 33 to 39.

What are you trying to solder? Just the motors? In general I would recommend 0.8 to 1.0mm.

Great. Yes, you should flash the cradio.bin. There are instructions in the wiki: http://wiki.bitcraze.se/projects:crazyradio:programming.

You would need to clone my repository and build the crazyradio firmware. After that you flash the resulting hex file to the crazyradio. This firmware has the option to change to PRX mode at runtime. By default, it should show the very same behavior as the original firmware (i.e. you can still use th...

I added support for the PRX mode a while ago: https://github.com/whoenig/crazyradio-firmware.
However, keep in mind that if you do make a mistake in the crazyradio firmware, you might need to get a JTAG programmer to reflash. (Entering the bootloader is explicitly part of the crazyradio firmware).

The ID of a button is defined by the joystick driver. If you use Linux, you can install jstest-gtk and see the mapping for your joystick. I am sure there are similar tools for Windows.

I wouldn't do it from scratch either. Step 2 in my previous list was more or less only there to understand the rest of the firmware. If you already understand how FreeRTOS works etc., you can go ahead and replace the controller code only. I don't know what an LQ controller includes exactly. However,...
