Hi everybody,



While going over everything one last time before inspection, I noticed that I 

neglected to install the limiting washers on the pip pin for the wings. I did 

install the spring washer on the spar cup, but for whatever reason never 

completed the "washer limiter" on the cockpit side.



I fiddled with it yesterday and realized that my pip pin is hitting something 

before the balls exit the spar cup hole. I can't see what it is hitting from 

the access hole in the belly and I can't see it from the side either due to 

the way I attached the wing root fairings to the side of the fuselage. I think 

it's hitting the aileron belcrank, though.



Has anybody had any trouble with this? If so, what's the solution? I thought 

about just doing away with the pip pin altogether and installing a similar pin 

arrangement as the right side.



Thanks!



Regards,



John Lawton

John

Yes I did, and Yes it is hitting the aileron "rocker plate"



Wiggle the stick and you will verify.  I ground off a 1/4" of so and got it working just fine.

John,

I remember that flight Crafters did what your suggesting and did away 

with the pip pin. I didn't, but doing it makes sense to me and If I had 

to do it over I would have. Just my 2 cents worth.

Hi John and all,

The pip pin MUST be fitted on the Port side.

It is there to stop the end of the Starboard spar tang migrating aft under  

load, and pulling the rigging cup off the back of the Port spar,  and jamming 

against the aileron belcrank.

Under load testing, [ for the 1370 lb upgrade ] we established that as  G 

loads are increased, the tang will move aft. The initial mod was to put the  

strap on the Port spar, to contain the starboard spar, but that failed to  control 

the rearward shift [ admitedly at loads over 8 G], so the pip pin was  

introduced, this does, with the washer bonded to the rear of the rigging cup,  keep 

it all together.

The pin needs to be shimmed forward, with the thin washers bonded to the  

port seatback bush, so the balls are up against the washer on the rigging  cup [ 

slight play is needed to ensure the balls always ''pop''  out ]

The aileron quick connect belcranks will need to be trimmed, there is a  

drawing of that , somewhere in the Manual [ don't have one to hand] but once you  

have shimmed the pin with the wings on, take the wings off, and refit the pin, 

 it will be obvious which part of the belcrank is in the way.

Have fun, but do take care !

Cheers,

Nev.
