I have an HDX-5016MDPL/TRX-100HD.  The tower doesn't quite
retract all the way, in order to allow for a TIC ring rotator.
I have a heavy prop pitch mounted and a 200 lb MontstIR.
I can still use the tilt over winch, although it is an athletic
event :-)  On the way down, the brake tends to overheat and
start howling.  My feeling is that retracting the tower all
the way wouldn't make much difference.  I had the same brake
problem before adding the rotor and antenna.  I am planning to
replace the winch with a W3000.

When doing rotor work, I extend the tower horizonatally to a
length of 50 ft or so.  Of course the tower is resting on
4x4s instead of being supported by the raising fixture.
