If pulling an aircraft backwards with a reversed tow bar, when the tail starts
moving in one direction, the tow bar will move in the opposite direction, thus
aggravating the situation. The idea might work if the rope is routed through the
tail tie down ring before tying it to the tow bar. Then there is the concern of
the rope damaging the com antenna.
If 120 volts is available, I like Jim Stricker's idea of using a hoist. Amazon has
a similar looking HOIST
for $80 with free shipping.
Using the pulley will reduce the speed and initial jerk.
