I just found something on Aliexpress to balance 3 (I think) axis on a telescope. I've often seen the question asked and have the same issue with both my Newt when I attach my full frame camera and my RC8. My RC8 I re-purposed the counter balance weight off a 12HP B&S ride on mower engine and a dovetail clamp so I can add some weight forward. I need more weight if I attach my full frame Nikon, hmm, I have dumb bells here (or am one).
Has anyone tried this system?
To buy the whole system bit by bit it would add up and I didn't see and mention of a complete set but I'll have another look.

It's still an interesting concept.
