Hi Jon,
Thanks for taking a look and your direction.
Its is a complex project and one I'm sure I'll learn alot from.
I have a pro Mini on order to complete the actual drone conversion (just have to wait for Australian post).
I'm gonna carry on and do the mapping to see what I can learn from it.
Should be a pretty cool thing to do.
I also hope to be able to learn a bit more about the sketch/C/C++ language.
Thanks again
