Hi All,



I've just bought myself a 582 blue top Kolb Mk.3 (not the xtra) as

I've always fancied one, but here in the U.K. they're like hen's

teeth, or very expensive.

I'd like some info as I don't have any basic info on the aircraft,

just the builders manual, no plans etc, I even don't know if there's a

pilots manual.

On inspection I found there were no aileron balance rods although the

mounts were there. Does anyone know what weight they should be please?



Many thanks, Norman

Greetings Norman, welcome to the list. 

The counterbalances are a solid steel bar 20" long, disconnect the aileron pushrod and slide the bar in and out of the mount until the aileron has a neutral balance. Secure the bar at that point.



Here is a little info:  http://oh2fly.net/oldpoops/Lexan%20rear%20enclosure.html

Boyd Young of the list sent me a PM, good question, he said: "Do you do this with or without removing the flap connected?    If with the flap, do you remove the flap pushrod? Explain Your answer..."



Wish I could, it's been long enough I don't rightly remember. I went out to the hangar just now and disconnected the aileron pushrod, and the aileron went to a neutral position, the counterbalance was pretty much aligned alongside the wingtip. Waggled the flaps and ailerons, and it kept going back to that general position. 



Which makes sense; where the flaps are attached to the back side of the aileron torque tube, they contribute a little weight to the ailerons, but at a very short moment arm.



I'm sure there was some info that came from Kolb, but I no longer have it, and obviously it was not in the original documentation. If I remember correctly (HAH) I raised the tail up so that the bottom of the wing was horizontal, disconnected the ailerons, and slid the weight in and out until the ailerons aligned with the bottom of the wing.



Why not call Kolb and ask them? Since they have been including counterbalances in the kits for over 15 years now, they will probably be able to tell you a lot better than any of us could.



I do remember that there was a lot of kerfluffle on the Kolb list the year before I installed them, which my airframe log shows as 1999. The list doesn't go back that far, it only goes to 2006, but if you do a search on "Aileron Flutter" you will see a lot of posts about it, it was still a big deal, but no specifics on how to install the counterbalances.

I experienced aileron flutter with all three of my Kolbs, US, FS, and MKIII.

I made up some counterbalance weights when I was building the MKIII because

I had a good idea I would continue to have flutter problems.  My weights did

more to aggravate flutter than prevent it.  First approach into Wetumpka

Airport went into flutter, snatching the stick out of my hand.  Got it on

the ground and removed them.  Anything over 80 mph and they would start to

flutter.  Could not get Kolb Aircraft to believe we had an aileron flutter

problem.  Miss P'fer was new, flew to Lakeland, Homer's in PA, and OSH.  One

eye on the ASI and one out of the cockpit.  Flew a photo shoot off a Cessna

210 at OSH.  He had trouble slowing to 80 and I went into flutter over 80.

Getting ready to do my first flight to Alaska.  Sun and Fun 1994.  Dick

Rahill was hauling butt back from South Lakeland to the UL strip with a

thunderstorm hot on his tail.  Turbulent air, WOT, all the sudden the FSII

went into violent aileron flutter.  Dick was white as a sheet when he

landed.  Got his attention.  Now they believed me.  Less than a week after I

returned to Alabama I had a set of FSII aileron counterbalance weights and

mounts.  I made them work on the MKIII.  Never had an inkling of coming

anywhere near aileron flutter after installation.  They work.
