Need Help DJI F550

[Mikegearin]

OK, just looking for some help.

Here is my ecalc link.

Can someone look at this and make some suggestions. The total weight includes my Sony NEX5. Just looking for someone to say if Im doing this correctly or going about this all wrong.

eCalc looks OK. 3kg is pretty heavy for an F550 though.

I can cut a little but not much. Was thinking of adding a second battery....What do you think?

Or what would be a better setup? Prop change, motor change?

Personally, I'd look at a larger airframe.

Im using the old Naza controller. Can you go with a larger airframe with that controller? I thought the F550 frame was the largest you can use without having problems. I had the extension plates with this frame and it just wouldnt fly stable at all
