You might study the method used to build the newer Kolb MkIII
wing...I think they use Bowden cables to actuate the ailerons and to
preserve the wing fold option...This method allowed the aileron to have
a bell crank in the middle.. That was years ago...and from my
memory...Saw it at the factory at Norm Labhart field...and haven't heard
if it was just a one off or if that method is still being used...
I suspect , in your case, it might set off a series of changes? Herb

Hi Bill,
I hope that I can clear some things up for you.
My Kolb Firestar plans are also dated 1993. This date is when you could no longer purchase a Firestar I and only the Firestar II was available from the factory. The 1993 plans reprint was made to cover both Firestar I & II. Actually, page 1 is still dated Dec. 1991 and was reused, but MOST other pages had been revised in 1993.
Do you have page 24 with copyright date of Dec. 1993, Rev 1? If not, you should have it. Aileron construction is shown on pages 10A & 10B. Since the aileron counterbalance was added at a later date, it was shown separately, on page 24. You may have missed this detail or may be missing the page entirely.
Forgive me, but I must also caution you about unintended consequences of your proposed aileron control modification. Where are you going to attach your pulley brackets? You need to be careful where you place extra holes in the wing spar and also be wary of any concentration of stress.
With the addition of an aileron counterbalance, the Kolb aileron controls are trouble free and no real benefit will come from their modification.
Now after that sermon, maybe it will make you feel better knowing that I made a "few" changes myself, including adding a flaperon control system taken from the Kolb Firefly. Good luck, my friend.
