For whatever it's worth, N0AMI (Jim), located here in Des Moines
recently replaced his Tailtwister with a G1000SDX rotor. The
tailtwister had finally failed after six years of turning the large
KLM Log Periodic (with the 40 meter kit). This antenna is on a 42'
boom. Ths antenna, however, is well below the maximum wind load
specified by Yaesu.
We installed the G1000 with high hopes...we all thought the control
box was rather nifty but we questioned the very light weight of the
rotor itself. Upon the 100th day of operation, the G1000 failed. Jim
has a weather station at his qth and had recorded no winds over 50
mph. We pulled out the new G1000 and replaced it with a spare
Tailtwister. After we got down on the ground, we discovered the
problem. When you shook the G1000, it sounded like there were scores
of loose pieces inside (probably bearings?). We didn't dare open it
up!
Sooo, based on that experience, I would think twice about using a
G1000 to turn any heavy loads or antennas with long booms.

P.S. The spare Tailtwister is still in place and working.
