RE: NEW DLE 20cc Gasser! (Data & Links 1st Post)
I believe Jody stated previously that he was getting 13 lbs 10z of thrust with that prop, if I recall that information correctly, transporting an 8 lb plane. Did I interpret that right?
Knowing that 1) drag is the opposing force of thrust, 2) weight is the opposing force of lift, 3) every prop has a different thrust and efficiency at given engine rpm and 4) various wing types (symmetrical, semi-symmetrical, flat bottomed, etc) have different lift characteristics ... in general, what thrust is required to lift and moderately propel a 10 lb plane? Assume normal flight and light aerobatics, not 3D.
