TopCap ARF pull-pull setup question
 

Hello Folks

This is my first experience with a pull-pull setup so please be nice :)

Just finished putting the pull-pull system on the rudder and elevator of my new Morris TopCap ARF.

Using Hitech HS-425BB Servos with Du-Bro Super Servo Arms, nice thin braided cable, and standard control horns.

The cables are tight ... very tight. I trimmed the control surfaces and when I give input into the radio then re-center the sticks, the rudder and elevator are out of trim again. Always out of trim in the direction they are returning from. i.e. ... if i give left rudder then re-center the stick, the rudder is out of trim to the left.

Will this problem correct itself with wind traveling over the control surfaces or will I constantly have to trim the plane in flight?

Please advise.

Your cables are too tight, they need to be taunt not tight. its pull pull not a band saw, just kidding.

LOL ... I will loosen the cable tension then. Here I was, all proud of the fact that they "twanged" like a guitar string and it was toooooo tight. Just when I thought I was doing good, I did it toooo good :)
