David Partridge, in the UK can also do PCB repair work.

Fritz, Glad you got it worked out though you had to buy the replacement. The PCB components are machine soldered at the manufacturer and are extremely difficult to remove and replace by most people.

Alright, thought I’d close this out. New board installed and zero issue now with the mount. Swings the RC10 around easily and guiding last night seemed to be alright (bit of clouds and only initial

Hi Folks, An official new version of Gemini firmware Level 6.1 and Hand Controller firmware v1.63 are now available for your Gemini. A few ways to update to this version: 1. Use GFU app (

Thank you all again for the incredible amount of background and help! I talked to Michael Herman in detail on the problem and it was decided that likely the best course of action is a replacement

Paul is totally correct.?? In general all Gemini's are repairable, 1s and 2s. ?? The only thing holding back some repairs may be PCB corrosion or intermittent faults!??? Older G1s are mostly a

Chip, Really very interesting. I just learned something new from you. Thank you. John
