I have cobbled together a set of English instructions for the G7000T-sx gyro. You can grab them from my website http://www.rotarsoft.com.
They are not the "definate article" and are not endorsed by JR, Horizon or MacGregor Industries in any way and are purely my own work from having owned lots of JR gyros and having access to a G7000T-sx. Please feel free to use them as you please until there is a definative set of instructions produced in English.
Obviously any errors.. problems.. issues.. you can send lots of email my way to complain and I will do by best to fix things.. however I think the instructions are complete enough to assist most people.
Slight disclaimer/thanks to Horizon/JR and MacGregor for parts that I have ripped out of previous Gyro manuals to make up the G7000t-sx instructions.. No point reinventing the wheel...
