I am using a 12x7 prop (per Horizon) and have tried with a few different batteries (3cell 1900-2200 range)25C cont/50C burst. I am running the same setup in a 260 EXTRA with no issues. I'm missing something

. All of my batteries are in good shape. I think that I will try a smaller prop and see what that dose. Not that it makes a difference but this is in a E-flight Taylor-craft 450.

I should go with a 40amp ESC
