First up, I should declare I'm Losmandy's longest serving (perhaps "surviving" is a better description
) dealer in OZ and I have been personally using his products for over 25 years now...
That said the 2016 G-11 is not the same mount he launched over two decades ago. The product has undergone continuous refinement for literally decades!
The current series G-11's have ultra-reliable new G-2 electronics, high torque motors, more accurate gears (actually... more accurate everything), improved clutch material, more rigid bearings, are lighter yet just as rigid as the early models and can now be split into separate RA and Dec sections for easier transport, with extended tracking well past the meridian.
The optional one piece worm block provides better tracking (some users report raw PE's as low a +/2 arc sec) and higher rigidity over the standard
assembly.
As for the payload...I find this figure a bit senseless.
Sure, you can stick 60lb on it...but it would need to be a very short optical tube. But if you are hoping to use a 18kg 6" F8 refractor, I suggest you look at the Titan...a 5.6" gear can only hold so much...
It remains my mount of choice for a "luggable" mount that I can run stand-alone in the field (i.e no PC required) off a 12Vdc battery and will remain in my field rig for many years to come....
