4.40 per minute = $264 per hour

Face it, that's what it costs to operate an airplane in Europe. We
charter the same plane for 180 an hour, and brake more or less even with
that. (I think we calculate our costs at 150 an hour, but I'm not sure.
Of course, we're calculating the full cost of operation.)

on an average of 4-5 tows per hour on a busy day,
that's 264/5 = 52 per average tow...

Wrong calculation. An average tow lasts about 5 to 7 minutes on our
field with average weather. When we have to tow further away, it gets
expensive.

no wonder you're making money.

Well, we're making money in our own pockets. Same discussion as above:
Somehow we must pay for our modern fleet. (Two LS8s, two LS7s, three
LS4s, two double seaters... with no hourly fees.)

Your 180HP Husky burns just a tad less fuel than a 235HP IO540.

But at approximately four times the price.
