The only significant difference between a GRII and a GRIII is the addition of a teflon bearing on the azimuth axis.




The GiroIII picture in the post following yours seems to show a teflon (or plastic?) bearing on the altitude axis too. Is that the case? My GiroII is metal to metal (plus grease) on both.

Doc,

Markus has one on the APM Germany site.

I have emailed him to find out more and will get back to you tomorrow.

I got your PM and will respond to that too.

The Tech2000 Giro 2 modification by Dave Masters is needle bearings which make for a smoother/balanced ride. You can increase the strength of the stock shaft with undercuts by using a solid shaft. Tech2000 machines all the modifications in house.

Included is a picture showing carry weight with the above modifications.
