If there will be any life in this thread, I could post some instructions and files how to bring qx3 to life. As for worn out gears, it easily could be fitted with 3d printed ones. To me to make it shine, this scopes need to be upgraded with modern camera module. digital blue never managed to update intel native softwave, so basically you have to use 20 years old program. Last time I used this scopes was win7 times. I own intel qx3 and digital blue qx7, which is essentially the same, qx7 is just much cheaper version.
