Interesting. You and I selected the same size battery for it with the 4s 4000. Mine is a 30-40C discharge.
I was running an 11 x 7 prop as I only had a 30 amp esc available but I think I may well up that to a 40 amp esc that I have available now for the rebuild.
In testing with an 11 x 7 APC I maxed out with 30.4 amps and right about 500 watts before with the 32.
It seemed to have lots of power even though I did not use much of it.
I had an experienced friend trim it out for me and he loved the plane so much he ran out and bought his own.
