X50 12s battery choice

[Fishingmadman1]

I'm running this x50 on two 4300 opti 6s battery's at the mo and find it to be to heavy can anyone recommend if I should go for the 2700 opti or 3500 opti ultras for weight and best flight performance for mild to hard 3d and possibly what difference in flight time might be
thanks

[GIXERMAN]

Never had one, but believe similar to fusion 50, which was good on 3300-3500 packs.

[Fishingmadman1]

And do you think 2700 would be to small as for flight times

[GIXERMAN]

Will fly very light and short duration, unless you won't to run a lowish headspeed.

Agree with Gixerman, best choice is 2 x 3500's! Will give you the best combination of weight and power capacity.

I run my X50 on 12s 2600 and 12s 3000. 2600s give four mins thirty,five mins on the 3000s of 3d.
