The v-bar needs a shorter throw as it needs less deflection at the head, not sure what the settings might be for the 700, however on the Logo 500 the balls move in from being 19mm from centre to 14mm (5mm difference).

I'm picking up a new 700le with the new V-bar with in built rx ad i was speaking to a mate at our club he has a velocity with a v-bar in and he said i need to put the linkages from the servos to the push and pull further in on the wheel?? is this true and what PCD are the balls you are using?

thanks in advance

Yes, it is true. The mixing levers on a flybar heli introduce approx 2:1 ratio between swashplate & blade grips so since in FBL this mechanics are removed, it is necessary to significantly reduce the cyclic servo throws. It is worth noting that this is true for any FBL set-up and is not unique to VBar.

Although it is possible to electronically accommodate I would not recommend it as servo resolution is lost so your friend is right and you should move the balls on the cyclic servo wheels by one hole inwards.

You will easily see if it is right or wrong when you begin the VBar setup as the collective slider position will show the error at full pitch +/-.
