Hello,

I have YS63 S in a 3kg plane. I have flied with 13*6APC with 20% nitro, but I'm not satisfied to vertical perfomance. Max rpm is about 11300r. It doesn't go vertically high enough, speed finishes too quickly. And I can't hover it, it hovers barely at full throttle, it should pull out from hover. Should I try some other prop, or is this just one "feature" of glow engines? With 13*4W, the plane would fly poorly at level flight, there wouldn't be enough speed. Or is this motor too small for this plane? With an electric motor in this plane, 16*10apc would be good. So it is maybe better than glow engine's small props, there is more torque but still it flies quite fast with that prop.
