I am looking for someone knowledgable with rigging floats and adjusting flaps on a 1967 PA-18. Something is not right as I must constantly hold right rudder and if I let go of stick right wing will dip. does anyone know a supercub specialist in the north Idaho area? Thanks in advance, Royce
 
There are TWO SuperCub Gurus in Hood River, Ore. if you'd care to fly out there. HUGE river & lots of docks there, :) These guys can accurately diagnose & prescribe over the phone, they know stuff!!

It's also where the WAAAM Museum is, which would be worth the flight in itself. www.waaamuseum.org & contact either Tom or Terry.
 
Call Jay at Norther Sky Air Center in Coeur d’Alene (208-762-9200, or cell 208-641-7707). He does alot of cubs on floats and you can't get more local than that. He is usually at the cabin on Derr Island on the weekends and can fly over.

I was just in Sandpoint last month. There is a guy from Alaska that has set up shop there at the Sandpoint airport and has a lot of cub experience. I don't have his information with me, but I am going to be back up there at the end of August and can get the info then. If you want it before that, let me know and I will try to contact my friend up there to get the information.

My friend had him do an engine change and Thrustline install and was very happy with the work/price/results.

You might try Keith at Montana Float Co. in Libby, MT...he's got plenty of experience in both SuperCubs and floats of all kinds.

The Cub is a very simple airplane. Borrow a smart level and take a few measurements yourself.

From your initial post, it sounds like your problem is only with the flaps extended? Any mechanic who can wire a turnbuckle can fix that.

One insidious problem is the aileron wash-in. Steve Pierce can tell you how a good aileron is washed-in - He has a post somewhere that explains how the trailing edge of a good aileron differs from the spar. The Smart Level is accurate enough to alert you of this problem.

The rest of the Cub is simply not difficult, and can be adjusted by any mechanic who understands the basics.

The person most on top of Cub rigging specs on this forum is Mark Englerth, and I know he will be glad to share Smart Level numbers with you. Steve is likewise willing, and is on top of this stuff.

Are you referring to washout that is adjusted by the rear strut or is this something different?

Edit - Never mind - - I just found this post that explains aileron wash-out http://www.supercub.org/phpbb2/view...&start=0&sid=aa621e8e870cd81f791c1fd6cb443412
 
did the plane fly good before floats???? Have you tried lowering your water rudders in flight to see if that makes a difference? If that does it, change the rudders only.

If not, then you really may have two troubles.

My plane, the beauty it is, flies a full 5 mph faster when the tail of the floats are off center 1".

Has your plane been wrecked???

Start by measuring from a marked spot on the bow to the center of the wing/wing strut attach bolt on each side. Use the same location on each side. write the numbers down.(use points that give you the greatest distance, this makes it easier to rig, two people needed!)

Now go from the strut/wing spot to the outside of the stabilizer on each side. Write them down.

Now adjust the fly wires to make each side the same, (1/4 inch is good, some trial and error may be needed).

If the plane is not perfectly strait, you may need to adjust the floats out a widget to get her to fly correctly.

Remember to write down where the final rigging was, or you do it again next year!

Kelly Mahon is in Sandpoint. I would look no further. Aweome pilot, a/p, and super good guy. PM me for details.
 
Guy's this doesn't have to be so hard of a deal to fix.

If the a/c flew straight before the float install, and now needs a little bit of rudder to fly straight, it's an easy deal to rig the water rudders so they have a 'trim tab' action on the air rudder.

It's impossible to fully-diagnose Royce's problem over the internet with the short statement he made, but, like I said, if the a/c flew straight before floats.........

PS. When a pilot/customer tells me his a/c doesn't fly straight, I quiz him and try to trick him with his words to see if he meant what he said. I usually end up flying the a/c so I can get it right......not everyone means what they say, and I hate to go tuning an airplane the wrong way because an owner told me opposite of actual conditions.

Royce, any more to add to your statement? That was Right Rudder Pressure required? It flies with the wings level and ball centered like that? What does "Right Wing Dips" mean? (a/c rolls to the right?) What's up with the flaps? A long straight edge on the bottom of the wing should line up with the bottom of the flaps when they are retracted. Is the flap issue something you had on wheels? Was the a/c on wheels? What else changed?

Anyway, ain't this fun? DAVE
