I loooove this little thing. Super quick and agile on my intended high power setup. The HQ bullnose props defy gravity, no matter what you put on or hang under. Even 3S kinda works, but 4S really puts a smile on your face.
The nanotech 850 45C is actually not up to the task; on punch out with fresh lipo voltage alarm instantly goes off. Probably need the 1300's. However, in the second part I tried 2200 and a Gopro on top. This works amazingly well as long as you pay attention to diving speeds ;)
Probably entirely not as MayMayDay intended, but this is my favourite setup now:
Morphite 170
Dys 1806 2300 kv
Kiss 18A
Naze 32 acro
HQ 4045 bullnose
First part: Nananotech 4S 850 45C
Second part: NT 4S 2200 25C
Immersion 600 mW
Aomway mini cmos (I really don't like this cam, has to be changed to CCD asap)
First part: Runcam HD
Second part: Gopro 3 Black
