Hi
I want to show you my last project.
let me know what do you think.
:)Thanks
Looks good, especially the logging shows you gave it really a good thought.
Is there a site with all the tech details, schematics, code, how you build it, what was difficult and how you solved things etc
Did you also get the other way around working? from phone to RC e.g. you could record all steering commands with your phone and replay them .... (in theory 
Take a look at ArduinoCommander app - https://market.android.com/details?id=name.antonsmirnov.android.arduinocommander.
For now it just only controls your arduino board, but in the future it will be available to bind android intents to actions, f.e. to switch LED on on incoming call or sms.
