RE: SAP 180 (Syssa Performance)
Wow! 22 lbs!! Perfect for a 3D setup - should yank a 12 lb plane out of a hover with no problem!
I measured my pattern combination with a simple spring scale (fish scale... not too accurate[&o]) and it pulls a bit under 15 lbs, but with much greater pitch speed (with the 15.5x12W) and much quieter.
