I wouldn't obsess over the gearboxes. The previous
design was quite solid and functional as well. And the CP3 is a
pretty-awesome controller that is behind thousands of awesome astrophotos out
Balancing an 1100 with a tandem bar and two OTA's w/o the
latest cam release levers isn't very hard. Before mounting the OTA's on
the tandem bar, I use a pencil on the floor to figure out the balance point for
each OTA separately by placing it's dovetail bar on the pencil and moving it
back and forth to find the balance point. I mount the cameras and other
accessories on the OTA's for the balance tests as well. I mark each OTA's
balance point with a tiny bit of painter's tape. Then I mount both OTA's
on the tandem bar, center their balance points on the tandem bar and then find
the combination's balance point with the pencil. With an estimated amount
of counterweights in place, I put the tandem bar on the mount and
center it on the marked balance point, crank it down really well and then mount
the two OTA's, centering each on their balance points. I then release the
RA axis locks (not the separation dovetail knobs!) and adjust the RA
counterweights. Put the whole thing in a known park position and then
start the electronics accordingly!
I hope that helps.
I got the 1100 with CP3 for a discounted price. But I
was not satisfied with the connection abilities of cp3 and so I purchased the
Cp4. Now I thinking about to update to the new gearboxes.
Sometimes it's better to check twice before you
purchase new stuff.
Do you know how much the new gearboxes costs? Because
I do Imaging with exposures up to 30 minutes p.pic. so I need a real perfect
My friend, unfortunately you got the old version of the 1100. I am afraid
you also got it with CP 3 box (you will have to check). There is nothing wrong
with this model however if you paid the full price of a GTO1100 CP4 then I
would ask for a partial refund.
It's like you are buying a 2017 car but instead
receives a 2013. In my case I'd be very disappointed and mad of course!
Good luck with the seller!

Here is one more picture.
There where the cover for the lever should be, is only blank metal. I
am completely confused now because without free moving axis I feel unable to
balance the system.

Could it be that my dealer sold me a GTO1100
with old gear boxes from the GTO900?

There's a cover over the levers that you just lift
