Kbar/vbar tail setup

[josh h]

Just a quick question people
im using a kbar I'm not totally happy with the tail setup, when I set the kbar up originally I couldn't get the number within the limits wanted, can't remember what they are now but 1 way was way out, down to about 60 whereas the other way was about 110.

The Heli flies fine an the tail is fine but it's just bugging me really,

so can I just go back in and readjust the tail settings or will I have to carry out a total reset up?

Cheers guys

You need to adjust the mechanical linkage to get the travel % in recommended range. Try one hole in on the servo arm, then re-adjust the software to give full travel again. One hole shouldn't make any more than 10-20% difference

its the length of your tail rod thats the problem. Depending which was its off in, you need to lengthen or shorten the rod, re-centre the horn at neutral stick and you should be good after a few adjustments. Id say you are in the correct hole with those numbers, you just need to adjust the rod length.

Yes, sorry, i misunderstood the question. If the travel % is asymmetrical then yes, you need to adjust rod length and centre the arm to get the tail slider to be mid way in it's travel range at mid stick.

Ok that's great, thanks guys.
i will have another bash at getting it right this week

For the servo arm you have on set the end points in the middle, IE the difference between the 2 limits you have now divide the difference by 2 so in your case 110-60=50 Divide that by 2 and add/subtract to your existing limits giving you 85 both sides. Remove your tail ball link from your tail pitch arm and give full deflection one way then the other and adjust the link until the link will fit both sides. You may have to alter your servo arm to put the limits in the right area and you will need to check the limits once adjusted but this should get you closer and more equal.

thats the way to do it - works all the time
