ultrix safe fight

My first flights were poor so Ive been trimming my ultrix 600 to get it more to my liking..
Its now how I want it, using an 800 3s Ive been seeing how long a flight I can get... This video is part of a 10mins 30 sec flight and the lipo showed 63% remaining..
Take off is nice and flat, switching over to as3x the trim is fine.. The glide power off is great.. It flies level on very low power
