thx a lot for all of your suggestions and code.

But I'm afraid I'll disappoint you both...

What happens is, this discussion started as a request for a solution (which I most thankfully got, indeed !!), and then it grew up a bit more with all manners of suggestions and snippets... which BTW I must shamefully admit that I DID ask for.

However, since my initial test and report yesterday, which showed that things were working as expected (on a number of repeated & controlled test flights), I didn't have any further time to actually PLAY - which would translate into mere flying and shooting, while forgetting all log checking, programming, math & physics for a while...

So, at the end of a busy day (yes I know it's Sunday...



Anyway, I suppose your suggestions will remain here in this thread, and I might revisit them in the future with a somewhat more investigative attitude... for now, they look just a bit, erm... too serious for me.
Thx a lot again, folks - and cheers !!!
