When giving these examples, you should include field altitude and density altitude to give us an idea of what was actually happening. At out field elevation (6,200 MSL) and a density altitude often over 9,000 in the summer, I suspect a 160 HP towplane with two occupants in a G-103 would only be doing taxi tests.

I have made several hundred tows in the 180 hp Pawnee with a 103 and ASK21, no problem! If I had my choice the 180 hp Pawnee would be my favorite.
