1st flight with a Pixhawk FC and on my rebuilt Tarot Iron Man

This was my first flight with my rebuilt Tarot Iron Man 650, and the first time I have flown using the Pixhawk flight controller. It is very different from the Naza's I am use to flying. The "Loiter" flight mode is really mellow, but when I put it in "Sport" mode I got a surprise. It was very sensitive and very fast.
​

 

It seems that Sport mode is hard to control

 

That's why it's a 'sport' mode, for those who like to actually fly using their own skills.

 

I accidently put it in sport mode today and almost crashed it going about 50MPH. When I realized what I had done I flipped the switch to loiter and it almost turned over from the momentum.
