The first time I used a GoPro, I took 24, high resolution photos, up my nose and missed the whole flight.
If you put the GoPro on the flyer, tape the little micro SD card in place with a bit of masking tape. Those little cards are hard to find in the grass.
I find that if I am having trouble keeping control, I likely need lower rates or have a balance issue.
Congratulations on the flight.
I like what you did with your TT. I don't think I have seen that solution yet. Pretty cool.
