Used a smaller wingtube just for the photos.
I hope so, but I don't know for sure.
With my C50 with 22x12E prop I can fly the F11 sequence with ease on a 4000mAh pack.
Hope the Advance will use the same amps as the C50..

They forgot your wing tube? [&:]
How did they assemble it in the photos you posted?
Do you think 4000mAh will be enough battery for the Advance in-runner?
Cheers,
Jason.
