I've tried everything, including a new gimbal. Performance is inconsistent at best. Actually got in touch with Live Help w/3DR and they suggest only the 3+Black or 4 Silver/Black. None of their literature excludes the 3+Silver, however. Is the 3+Silver compatible or not ? Thus far it looks like a resounding NO. Any suggestions, please ? Camera works great with the Solo's non-gimbaled mount, and works just fine in stand alone mode.
