Battery Recommendations for Flyfish Volador 3.5 Build

Probably just try a couple of different sized 6s batts, from a reputable brand like tattu or gnb or something. Maybe something 600-1000mah, just see what combination of weight and flight time you prefer.

I've been really enjoying 650mAh for 3.5". The ones by Zeee are the lightest I've found by a good margin and have been very reliable for me.
