Sorry Rodpad, I'll put it in 82yo language, I use VLM to develop my waypoint missions and do a Google Earth Fly path check each time.. I also use Litchi itself when I'm not greatly concerned with elevation.
Strange - last time I used VLM .. and actually demonstrated to someone (around mid August with my Mavic Pro) .. the altitude profile was definitely working.
OK - I have a key - and VLM is mainly working. Many thanks.
Initially I kept getting a strange ".. mission names must be alphanumeric .." which they are. But closing VLM and restarting seems to have solved that issue.
The only thing I'm missing...
Done that bit .. then it's all a mystery.
I did .. but not enough detail for my brain and skills.
Ooo - cool - I'll take a look.
I got to the Google Billing bit .. and my registered credit card was used.
Thanks both!
