    Big Boy
    Made a little flight last week to Medicine Bow, Wy to see Big Boy on its way to Utah.  These were some of the last steam engines and the largest.  The UP RR owned all 25 of them built back in the 1940's.  It is headed back to Cheyenne next week and we will fly down to see them again. The first photos are of Medicine Bow airport, part of the transcontinental mail route so a couple of pieces of transcontinental history, rails and planes.

    The Back Country Super Cub or carbon Cub are great planes if you have the need to carry loads into short strips but having test flown a couple, dang I still really like flying the Avid MK IV .  Maybe a Highlander with the Yamaha, they can carry nice load and you can sleep in it if need be.  But hey I'm happy with my Avid.  Sure would like to have a Kitfox SS and Highlander for a couple of years to really get the feel of them both for a side by side comparison but no one has offered so far.

    There was a pretty simple setup for that posted here or on the Yahoo sight I believe. Check the files section on Yahoo first.

    I just have used push lock hose and fittings on all of my installs.  Bought it local from hose supply store, fittings are a bitch to get on the hose.  Any hot rod shop will have the hose and fittings also.  I can take a look at the hose I used tomorrow but there are several brands besides Parker that are all the same. None of them are metric. Rotax use standard hose fittings.
    To be a little clearer the fittings are AN-8 and the hose is 8 or 1/2"

    Leaky tank repair
    A fellow here with a KF 4 had one of his tanks leaking and I suggested coating with Caswell Tank Sealer.  I an happy report that he was successful by removing the wing and rolling it for about a half hour with two people.  Long term will give the Paul Harvey to this operation, sorry The Rest Of the Story, for those of you that did not grow up hearing him on the radio.  This is the product that I used to coat my tanks before installing them.  It also makes them alcohol proof, not that I would put that junk in my tanks without being in a jam somewhere.

    It would be interesting to plot the KF 4 airfoil in comparison.  I know VG's have been tried on the lower surface but I have often wondered if they were placed far enough forward.  What are your thoughts on placement (% of chord) for them on both the upper and lower surfaces?  I have plenty of them around but I guess I have been to lazy to date to give it a try.  I do know that the KF 4 is faster than the Avid MK IV even with the added area.  It will be interesting to see if Manu's wing is faster also.  I install the KF leading edge on my wing and I believe it is a little faster. 
    PS I do have VG's on the top of the wing.

    Then of course the next step is to build CF ribs.  BCSC has such a set of wings setting in the loft built for a light sport super cub. I will ask Bruce about the weight and etc when I think of it.  I know the cost could take your breath away.

  12. wypaul added a post in a topic Cabane installation   

    That seems to be the common issue.  Here is how to build a simple tool and while you are at it make one for installing the wings. Take an old bolt (1/4") for the cabane that is long enough to fit all the way thru. Cut the head off and taper the threaded end.  This becomes a drive thru lineup pin.  Drive it into position and then drive the pin out with the bolt.  That will make the job doable but if the alignment is really bad you may need to convince it with your drill or actually tweak the cabane a little to make it fit.  Been there, done that, now I have different custom mounts and cabane that actually fits.

    I did find the Pro Strength aggressively removed the PolyTone and the regular worked with only slight lifting of the paint.  The paint thinner/mineral spirits worked without lifting the paint at all.

    I did try that but still managed to break one so then used aluminum channel that I shaped.  In fairness I only used thin boat glass and 2 layers.  Getting thicker layers to make the sharp corners is a problem.  I'm not saying it is not a viable option just my experience.

    I know this is an old thread but found out today tha mineral spirits removes duct tape glue without touching PolyTone paint.
