Skywatcher Skyliner 200P FlexTube GOTO drive slipping

[scruffy74]

Can any one help me my Skywatcher Skyliner 200P FlexTube GOTO wint drive the scope up when it gets to a certain angle. Has any experienced this before or know how to compensate it. The drive seems fine it's almost as if the scope is to heavy when it gets to a low angle. Any advice or help is welcome.

My old 12" Flextube used to nosedive if I put too big an eyepiece/barlow in, or had too many accessories at the front end (Telrad, wixey, finder, handle, dew strap, etc). It all adds up and the simple solution was to add a counterweight at the primary mirror end of the tube. Hth

As mentioned it needs to be balanced.......

Thanks for the replies. Where did you get the weights from if you don't mind me asking as can't find any for a dobsonian. Cheers.
