REFLECTOR: Aileron Rigging 2

Fri Sep 9 23:36:21 CDT 2011

Alex, 

I saw your note and wandered out to the hangar to measure. In my 173 FGE, the hole in the keel is 3-3/16" wide. My control stick is 3/4" wide. 

Gently moving the stick side to side, the stick does not touch the sides... but it comes very close (maybe 3/32"). If I torque on it a little bit... it does hit the side. 

If you try other methods and don't get what you want, let me know and I will tell you what I did. It didn't take much... but it made a Big difference.

Thank you everybody for the assistance- I have re-rigged theapproach angles for the cables to the wing control horns to 90 degrees from theoriginal 105, but that just made the up and down equal, I still only have about4” total throw on both ailerons- about  2 up and 2 down- I am thinking thatpossibly my stick is hitting the keel prematurely ( keel hole us under-sized) wouldit be possible for anyone who has proper travel to measure the distance fromthe side of the stick tube to the edge of the hole?   The hole looks plentylarge, but maybe it just is not-  otherwise, I will resort to Kurt’s plan “B”and decrease the distance of the mounting holes at the aileron control horns.

I could not get any where near what was recommended for travel. MyDad came by and I picked his engineer brain to see why Iwas apparently losing my mind. Only took him a few minutes to findout that, with what was supplied from Velocity, and the instructions, itwas impossible to get the recommended travel.  

It was discovered that the only way to get the recommended travelwould be to get new cables with more travel, or change the arm on the aileronbell cranks.  I opted for "B" (changing the hole location onthe bell crank). 

I now get 2.5" up and 2.4375" down on both sides. 

I too had to change my aileron cable approach angle to 90% fromwhat  was in my book. I ended up drilling a second attach hole 90_degreesto the first one (watching proper hole spacing). 

Works like a champ now!

Interesting the manual now says 90 Deg angle from the cable to thearm  I know my manual did not say that . Next time I 

am at my hanger I will have to look at the manual  I am sureit was 110 deg. Of something close to that.

Per themanual  When the stick is
fullydeflected, you should get at least 2-3/8" of deflection at the inboardtrailing
edge of theailerons, both up and down. A properly rigged system will get approximately

2-1/2” of bothup and down travel.

I thought that it was better to have asymmetric displacement, i.e.More down aileron than up (equal side to side) in order to minimize adverseyaw?

I had the same problem worked on it for what seemed like forever.My problem was the push pull cable angle.

It has to be 90 degrees to the arm.   The manual gavesome angle of 110 I think that did not work for me  at all.

Once I got it to 90 both up and down were equal. Worked for me  good luck

For all those that have been here and solved this fun Geometrypuzzle:

I have just been around to checking my flight control throws,since

hopefully they will be put to actual use soon, and my ailerons area bit out

of adjustment-

Symptom: Both ailerons have 4" of throw (as measured at theinboard end) but

the right one has "normal" movement with 2-1/2"inches down, and 1-1/2

inches up. But the left side is exactly the opposite, with morethrow up

than down.

1) both ailerons are exactly neutral with stick neutral.

2) both aileron  control arms are at the same angle withrespect to the

wing/aluminum brackets when neutral.

3) stick throw seems to be identical right and left, but I don'tthink that

any slight difference in this would cause this particular problem.

The only thing I can think of is that the horn on the keel end ofthe

aileron torque tube is not exactly aligned with the stick,- I wasnot able

to directly measure this yesterday since there is a lot of stuffback there.

Any help would be appreciated.

Thanks

Alex
