Pull-pull system
Hi Rezah,
I need some help with my pull-pull system, I use all the stock parts that came with the kit. My problem is that when I try full deflection to one side, the cables stay with good tension but to the other side some how??!!! the cables (both) lose tension and that of course create free movement on the rudder.
I don't understand how both cable lose the tension at full deflection.....I know that is weird....any help......
Thanks,
John

In that case the only way both cables can loose tension in one direction is if the geometary is such that the cables lengthen in that direction, sorry to ask a dumb question but have you the rudder cables connected at the hinge line i.e. 1 1/4" in front of the control horn.

RE: Pull-pull system
Thank you guys, I'm going to recheck but I'm almost positive that I installed that way....but also I remember now that there were two holes to install the control horn on the rudder....with one you guys use??

The one that's 1 1/4" away from the hinge line, if your cable pull point is in front of the hinge line when you move the rudder the cable will in effect get longer, I still don't understand why it only happens in one direction though, check that both control horns are the same length.

Mike,
Let me see if I understand you are saying that the point were I connect the cable to the control horn need to be align with the hinge line, because the first manual show something different.

Hi John,
From the two holes, the one that is more forward is the one you need to use. It seems to me you have the old manual. Please download the new manual from www.qqaircraft.com That would answer most of your questions. Let me know if you still have problems.
Thank you,
