Hi everybody,
 
I'm a mikrokopter user now and observing your works from this group for a long time. Now I want to try your software on my current hardware, but...
I want to ask, is there anybody tried this before, or there are any technical (or?) restriction prevent this implementation?
 
Thanks
 
Erdem
