I would say 1606 is a perfect size for acrobat. Aparently it is not a normal 3 inch, it is much bigger. flight time, i didnt notice, tell you when next time i fly it.

I’m about to finish mine, with Emax RS1606... Planning to use 850mAh 4S on XT30, but I’m wondering if I better go for XT60 so I can run bigger batteries (1000-1300mAh) and avoid sagging & extend flight time. Sounds like you’re happy with yours, what battery are you using? Thank you for sharing, I appreciate it!

previously i use XT30 for my 3inch build for the sake of beauty. now I go all the way XT60 for any motor bigger than 13xx. On spec, XT30 is too small for any 4x motor which will draw more than 10A each.

i mainly use infinity graphene tech 850mAh 85c, 3S or 4S. but 4S will give significant noise to the fpv feed. So, i love 3S more
