Hi XJet I think you missed that part.
Nope -- it's the 1/3 throttle to full throttle transition that seems to be the main problem (in my experience) with many cheaper engines. 1/2 to full is often okay. When flying 3D, 1/3-full and 1/3-2/3 is a range of movement that's used quite often and you can't afford any hesitation or stumbling.
