Dougs experience sounds almost exactly like mine.  My ordeal with RDD =
ended
about 12/07.  Replaced the alternator on arrival home (bad batch from
Kelly).  Replaced the accessory drive pulley soon after.  On board =
computer
indicates the system is working but the ice I've been in in 3 years has =
not
all been prevented.  Anyone know how to test the pads directly?
Since parting (unsatisfactorily) with RDD I've talked to Doug Goodrich =
at
Goodrich Aviation about my system.  Anyone had any contact with him?  =
He's
Kellys east coast installer.

I have had the thermawing system installed by RDD=A0=A0on my IV-P =
turbine a
couple=20
of years ago.

The computer controller failed within a few weeks and had to be =

The=20
alternator failed within a couple of months and had to be replaced
(involving=20
pulling the prop). I developed an oil leak around the prop after their=20
installation. Pulled prop and found that NO gasket was re-installed when
they=20
had reinstalled the prop. The wiring connectors were not aviation grade =

fact, they were not even OEM auto grade, but appeared to be K mart =
grade. I

and had to be replaced.

When the system is on, I have a very annoying alternator whine =
constantly in

headsets.

The heat units on the wing have many folds and uneven areas, =
particularly on
the=20
bottom of the leading edge. I brought this up to Dave McRae (one of the =

principals of RDD). He told me to my face "we did not charge you enough =

good job!!!" It seemed to me they charged me plenty, and I paid them =

I would advise that, if you consider having RDD install this system, DO =

leave your airplane unattended during any aspect of the work. I =

I hope that, if and when I do need it, it does not fail at the worst
