Despite I have (http://www.mobiflight.de/forum/topic/55.html) bad experince with your software , I want to try it again. I want to build an FCU for aerosoft airbus.
But I have question;
I am plannig to order (http://www.aliexpress.com/item/New-10pcs-12mm-Rotary-Encoder-Push-Button-Switch-Keyswitch-Electronic-Components-hot/1787766377.html) rotary encoder (x4) and(http://www.aliexpress.com/item/High-Quality-4-Bits-Digital-Tube-LED-Display-Module-Board-With-Clock-Display-For-Arduino-DIY/2038575854.html) led displays (x4) and some on/off buttons. Are those going to work normally with this software? And how many pins I am going to use on mega board? I may order 2 of them if necessery.

Thanks.

The rotaries should do fine.
The LED module must be based on max7219 chip, eg http://m.aliexpress.com/item/32265982428.html
The module of your link is based on another IC.
I hope you have more success this time with MobiFlight.
For each switch you need one pin.
For each rotary you need two pins.
For a LED module you need three pins but you can daisy chain up to 8 modules without needing more pins.
