The TR gearboxes were impressive for the size. The B2B isn't all bad.
I tried to buy the ones off the crashed one, but they wouldn't let me.
Like I said, if they weren't housed in 2" galvanized pipe fittings,
then they were in something else that exact same size and shape. If
you have the blueprints of the gearboxes, I'd like to see them.

SNIP. There were
two gearboxes on the tail boom. One was at the apex where it makes a
45 degree turn upward. The other was at the tail rotor.

This extra 45 degree gearbox seems to be a waste. It adds a lot of
extra weight and doesn't buy you anything. I will have to admit that
I was fascinated by the gearboxes themselves. They appeared to be
made out of 2" galvanized pipe elbows. I'm not sure if they really
were, but that's what they looked like.

I have to come to the rescue of the B2Bs T/R gear boxes, having overhauled
many over the years..
It is a brilliant system that will happily run to it's (1200hr) overhaul
life with no maintenance other than checking the oil level every 100hrs.
Then most of the time at O/H will require virtually no replacement parts to
put it back in service.

Mind you our ships did pipeline patrol so did not sit around to corrode.

The Brantly T/R drive system of cascading oil lubrication is the BEST of any
helicopter.
