Listers,

Need to fix a slightly heavy right wing on a new

rocket. Please correct me if I am wrong here.

Seems one should squeeze the trailing edge

of the light wing.  Correct???

Thank you, Stewart Bergner

That's correct, Stewart.  Gently squeeze the trailing edge aileron of the 

light wing. I simply used the pliers with the wide lips with some cloth to 

prevent scratching the paint.  I would squeeze a small amount and then move 

it down the full  length of the aileron doing the same.  Then I repeated the 

process. Did it three times.  I didn't want to distort  the metal by trying 

to squeeze it down all the way in one location the first time.   Did just a 

little bit each location before moving the plyers.



 I did it  on my right wing (Left wing heavy) and it complete corrected the 

problem.  I suggest  to do it in stages so that it's not over done.

Van's has a useful document on this subject.  It should be read  

before you do anything, as there may be other causes for the heavy  

wing, and you ideally would attack the root cause, rather than just  

treat the symptoms:

My fix for a slightly heavy right wing was an aileron trim tab.

The "tab" is a wooden wedge from the hardware store, intended to  

secure the head to a sledge hammer.

I bonded it on using double back tape, test flew it, trimmed it for  

neutral roll, painted it then bonded it with a dab or epoxy.

It's on the underside of the left aileron, unobtrusive and completely  

effective.

Later I installed Van's aileron trim kit and think I should have done  

that first.



BTW, my fix for a half-ball yaw caused by my imperfect installation  

of gear leg fairings was to align the fairings using washers stacked  

to 1/8 inch between the trailing edge of the fairings and the bracket  

on the fuselage.

I have found that the aileron brackets have not been installed exactly the same for what ever reason and one end of the aileron hangs lower than the other.

You are correct the fix is to squeeze the light wing's aileron.
	




I have done this successfully.  AND I did this very carefully.  What others 

have said here on the list is very true.



First, check all other things per the Van's document/instructions to see if 

anything major is at fault.  Then if that does not give you resolution, very 

very very gently squeeze the light wing's aileron all across the length of 

it.  I mean squeeze it so you do not even think you are doing anything.  Go 

out and fly.  If the wing is still heavy, tighten the adjusting tool about 

1/128th of an inch.  Resqueeze.  Test fly.  Keep doing this until you find 

the right amount of squeeze.  After I corrected the problem, I cannot even 

see that I changed the aileron one tiny bit.  It is very very suttle.
