Hello good day to all-I upped the head speed from 2275 to 2325 and its a little better -any more and it will kill the flight times-getting four and a half mins now-I might have better luck if I post this in the v-bar forums-c ya

I would double check that your geometry and linkages are all correct and the vbar is set up properly. You shouldn't have any wobbles, I can take my Headspeed down well under 2000 without any wobble.

I am using the blue vbar and running an Align 700mx 510kv motor.

What are your parameters in the vbar?

v-bar setup

Hi Shortman-moved the balls in one hole for a total of 20.35mm
--collective travel 98 percent at 12.5deg
--cyclic travel 95 at 8deg
The style is at 60
The ag is at 106 and the rotor gain right now is at 85
Once I moved the balls in it flew a lot better and as other people form the forum said to run less pitch so I dropped it down to 12.5
The links r as per jr,
I switched 2 wide cord 620 blades and it seems to like them the best,it a little harder on the packs but it not that bad-everything comes down a little warmer-iam using the 700mx 610 kv like u and so far its been nice-any thing u c here that u would change shortman-thanks for the help.Erik
