REFLECTOR: Fwd: Aileron Rigging

Tue Sep 6 19:08:19 CDT 2011

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

It was discovered that the only way to get the recommended travel would be to get new cables with more travel, or change the arm on the aileron bell cranks.  I opted for "B" (changing the hole location on the 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% from what  was in my book. I ended up drilling a second attach hole 90_degrees to the first one (watching proper hole spacing). 

Works like a champ now!

Interesting the manual now says 90 Deg angle from the cable to the arm  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 sure it was 110 deg. Of something close to that.

Per the manual  When the stick is
fully deflected, you should get at least 2-3/8" of deflection at the inboard trailing
edge of the ailerons, both up and down. A properly rigged system will get approximately
2-1/2” of both up 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     adverse yaw?

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 gave some 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 Geometry puzzle:

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

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

of     adjustment-

Symptom: Both ailerons have 4" of throw         (as measured at the inboard 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 more throw up

than down.

1) both ailerons are exactly neutral with         stick neutral.

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

wing/aluminum brackets when         neutral.

3) stick throw seems to be identical right         and left, but I don't think 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 of the

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

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

Any help would be       appreciated.

Thanks

Alex
