Hi Ed, Interesting... I have been towed by a Supercub and that was indeed phenomenal. Behind an Archerokee it was always a case of keeping your glider down so that the tug wasn't hampered. Behind the supercub it was a case of doing your best to keep up - God did those supers pull (by comparison). They even made short work of the Bocian!
It's easy to imagine, then, another eighty horses in a stripped Bird Dog. Pawnee...? Heavy tank? But I did read somewhere that they make good tugs with a four-blade. Even though they were built for ag-work.
Mind you - my best tow was behind a Super Chipmunk - but what a waste. It's like putting Arkle and Red Rum in the traces of a milk float.
Anyways... slipping the dog...
