Ok did my research and ordered Vbar and RJX head.Stuff arived Friday got it installed and updated to 5.1pro. Did all the pc setup. Set end points and centers in radio.cyclic pitch is 8 deg. As soon as I unhook from the PC it overdrives the cyclic to the point the ball links pop off. Watched Mr Mells vids twice nothing seemed to help. Do I need to change endpoints after already setting them in Vbar setup page?
Thanx B

You need to center the servos.

You need to lower the cyclic ring value. It's under the expert parameters menu (blue/purple icon) on the swash tab. Drop it by 20 points or so and work your way back up. Remember to press enter when you change the value. You can test the effect of the change once you get back to the main screen. Modify the value until it doesn't overdrive the servos.

The first thing he needs to do is center the servo.

Still working at it
Thanks guys,
The servos are centered and all linkages squared up. I was looking for the cyclic ring in cyclic tab but its in the swash tab.I have to set cyclic ring to 50 and then I still get 11 deg. of cyclic travel.Some of the binding came from the newer swash style being different from the old (less clearance for the elevator ball link) Will this be too low? It has push pull setup so I cant move the ball links in on the servos even.

Mr Mel
It is a preddator gasser with RJX head stock swash. My collective value on setup is 80 for 11 deg. My cyclic value is 80 for 8-9 deg. When I exit setup full cyclic throw is over +12 and the swash ball links pop off.
