Out of RAM space

Well, the Arduino SRAM start to be too small for this application (no surprise). I coded too many static objects in a first implementation, so it went out the 1kbyte of memory. After some new lines of code, it's much better. No more RAM problem. But now, Flash memory space is reducing a lot. There is only less than 5kb left and only few more features will be integrated.
So few features implemented: servo neutral, servo course high and low, and transmission type (RC@Home, O24RCP) so that O24RCP receiver can be used.
I'll provide some pictures of the screen soon. But the story with this hardware will finished shortly, I believe I can't do much more without rewriting a lot of sofware.
