Hi Couple of questions: Does the motor and current indicator flutter when the clutch is disengaged and the motor is running??? Does the Scope move cleanly with...
Hi Interesting, the ones on mine are 8 x 32. I wonder if they didnt bother to drill and tap for full size screws if they were not to be fork mounted. They...
Don, Bud & Phil! Thanks for the replies so far! Your answers seem to differ so I am still confused .... Maybe it is different on different models? Notice I...
There may be differences as a consequence to when the scopes were produced, and what fasteners supplies were on hand. Try taking one of your fasteners...
... It looks like you have a #10-24 in the picture. The diameter of a #10-24 is 4.828 mm and the pitch is 1.058 mm, which makes it slightly smaller than an M5...
Hi, the answer to both questions is yes. the flutter is only noticable when slewing west but when it's happening it will do it with the clutch disengaged. all...
Carsten, Looks like a 10-24 to me. One way to be more certain is to take a metric ruler and see it the threads will come close to each mm marking. If it does...
