Hi,
I too got in around 30 mins of flying today. I didnt do as much mission stuff as planned as the wind was way higher than I was hoping for. I tried for some slow stabilised shots, I'll see how they came out.
I switched it up and flew at another oval near my local headquarters and gee did I draw a crowd, I had about 10+ people from various parts of the ovals stop and watched me. I had to make sure I looked the part so no major stuffing around.
Crispy, it sounds like your mission wasnt uploaded correctly. If using droidplanner I firstly save the mission, then I upload it to the APM / Pixhawk, then I download the mission from it to verify it got it correctly. It is also a good way to check that home is where you think it is :-) That should show you straight off if it uploaded correctly, if not load the saved file and try again :-) Also when you say fast speed, what sort of speeds are you talking.
I now take my Tri upto 65km/h, I had an issue earlier on where I would try to keep below 40km/h but it's handles the fast speeds well (it does a better job than the mini quad does) - it was due to a dodgy motor so I lost trust - it's now regained. I'm thinking since I've had 3.5 hours of crash free running on the Tri since the motor change, I'm thinking of putting my gopro on the gimbal :-) But I'll most likely wait till I've got the CF frame completed and have a few hours of running on it. I really want to get some 2.7K - 25fps footage, 1080p is good but, nothing like some real HD footage.
