Hi.
I have just built my first quad having installed Pixhawk on board,
Have just flown it for the first time in my small garden. It lifted of really smooth and took it just above fence height to try and keep out of prop wash, had it in Alt Hold and was very impressed how it held its position it flew for 15 min, having let the battery rest for 5 min it still had 15 volts left. Battery is 4s 8000 weight of quad is 2162 grams. Hope to use the auto tune as soon as the weather picks up. What I would like to know is i am only using 16% throttle for it to hover as soon as I increase to 17-18% it starts to clime is this ok or is there something I should alter, any help would be great full.

Tarot 650 ( arms extended to 680 )
Motors MT4108 KV: 370
Props 15.5
Battery 4s 8000
Minim OSD
Gimbal not fitted till tests are complete
This will add 300 more gram Total weight of quad 2462 grams.
