Well, my first full test flight today

Roll P4.0 I0.022 D21
Pitch P4.0 I0.023 D21
Yaw P6.0 I0 D0
Alt P8.0 I0 D12
Vel P4.2 I0 D14
Level P9.0 I0.045 D0
RC Rate 0.99
RC Expo 0.65
Just as everything was going great - the battery ran out of charge

I sat and charged and balanced the battery and ventured back out.
This time quad seemed very responsive, but managed to get it to hover again - then....
Gust of wind hit me, i pushed throttle and then quad shot off. I managed to cut the throttle in my panic and then promptly found out that the legs of my quad have very, very sharp edges as i managed to catch my quad before it dived into the ground.
Now sitting here with my right hand covered in a bandage and plasters

I wasnt going to be beaten, so I went back out - tethered the quad to the ground and tried again.
This time the quad is very responsive, so responsive infact that I am finding it very hard to control never mind hover.
Is it possible to make it slower to respond? I am new to RC flying, so all I can think is that the battery has never been fully charged while I have been learning.
Many thanks for any advice.
Cheers
Iain
