Hi Guys



I'm installing the pitch control bellcrank 7-C-1-1 to the pitch  

control rod 7-C-1-3 and I can't seem to find a reference to the  

neutral position of the bellcrank. Is it meant to be perpendicular to  

the cabin floor? The rod will end up being a lot shorter than the  

685mm in the drawings. Jari, you had the same question back last  

summer...



And for that matter, the control stick is meant to be neutral  

according to taste. Without the seat cushions in I can't really get a  

feel for that. Where did you guys start from?

hello

I have built a couple and I just made them  perpendicular ,otherwise the bellcranck get tight or hits the back of the seat  and does  not reach full deflection

and yes it would be a bit shorter

I am at the same point as you are and have been considering the  

problem for about two weeks.  My pitch control rod (7C1-3) is 685 mm  

long and from the picture in the plans of the Horizontal Tail  

Bellcrank (7C1-1) I assume it is to be perpendicular to the cabin  

floor.  I just checked mine and when it is perpendicular to the floor  

the stick is full back and lateral travel is greatly restricted.  In  

other words, you would be not be able to bank the aircraft to any  

degree and would have no up elevator control movement left.  With the  

Pitch Control Rod at 685 mm and the stick at what I would like as the  

neutral; the top of the Horizontal Tail Bellcrank comes in contact  

with the seat back channel.  I have queried Zenair about this but have  

not received a reply yet.



I think you have solved my problem with your question.  I now believe  

I need to shorten my pitch control rod so that the Horizontal Tail  

Bellcrank is perpendicular to the floor when the stick is in what I  

want to be my neutral position.  That will have to wait until the  

cushions are installed or, at the minimum, their dimensions are able  

to be simulated with some degree of accuracy.



I stand ready for correction and/or comment.



Sorry to interrupt the stream of speculative comments about accidents.
