[TowerTalk] HYGAIN ROTO-BRAKE

[David L. Thompson]

There were several different models of roto-brake.

The first was in the 50's and the was just a brake that sat on top of a
rotor.  They even gave you a world globe/map option.

The second was in the early 70's and it was like a model 300.  Was just
medium duty.  Then about 10 years ago they made a fairly heavy duty job.

probably need to find some numbers on something (brake etc) and call
Hy-Gain/Telex.
