    Actually I am building a full scale Super Cub replica. See it here:

    Status: offline     		Nice Cub replica.

    I have just discovered a missing item on the drawing. On the right hand end of the wing drawing where an arrow points to F15, there needs to be a rib installed between the ends of the open sheeting. If not there will be a big open hole there and the top sheeting will not be supported on the end. I believe a 2/3s rib made like W1 will work fine and I don't belive the shallow slant will make any difference. Of course the back end of the rib will have to be adjusted to meet F14. There may need to be a second rib glued to the new rib outboard with a 0.030" recess to allow the top window plastic to be installed.

    I waited to cut F13 & F14 until I measured the distance between F15s at F16 & F17 as built so that I would get a perfect fit. Since Wendell only generated half patterns on F13 & F14, I removed the correct amount in length from the pattern center line end. Now with a perfect fit at F16 & F17, I noticed that the W1 ribs were not the same distance apart at the front as the back. I placed F14 over F13 with the C/L matching and found that I needed to remove about 0.050" from both ends of F13 where the W1 rib shoulders up. Now every item fits perfectly and the W1 ribs are square and equal distance. If you don't check that the W1 ribs or equal distant you may find that the wing has a gap when you slide it on.

    I apologize for making you all sleepy reading this but it's getting late and I'm sleepy from writing it.

    Post more pics as you make more progress.
    Is that the Stokes pic in back ground of Corsair on carrier landing?

    Happy Holidays to all !

    Have you been making any progress lately?
    I just recieved my 3W today so I'm charged up!
    Should see regular progress from me again soon.

    Status: offline     		Hi All,

    Not much progress , fuse sheeted with minor changes to get better cowl fit.

    Lee what engine size ?

    Ken your wing center section method is the way to go, F-14 as shown on plans in F-3 cross sectional view is too short , use wing top view for correct lenghts.

    I'm trying to make some progress but time does not permit much !

    Happy Holidays to All ! Jeff

    Status: offline     		Jeff, it's a 3W78B2 with all the optional goodies. After looking over all the specs the price is right. It has a little bit of extra weight at 6.5 lbs but I've been planning for extra weight all along.
    Its like a computer. Two years ago it was the cat's ass. I'm pretty happy with it ; I even took it for a walk to my neighbors tonight.

    Word to the wise....DON'T TELL YOUR NEIGHBORS WHAT YOU SPEND DOING THIS STUFF.


    Later.

    Status: offline     		Yes Jeff, that is a Stokes painting of Corsair #13 on final. A little trivia, #13 is the CAF Corsair based at Lancaster Texas. However, when they repainted it about 3 years ago they chose to do it after a real Corsair, not the fictitious #13 one. It was repainted like the famous #530 of Marine Squadron VMF 312 (Checker Boards) flown by Lt. M O Chance. You can see my #530 on the last page of my gallery on RCU. It's powered by a Brison 5.8 and is exciting to fly and watch. When the Vought retired employees were looking for a Corsair to restore they acquired an FG-1D (Goodyear) and after restoration (#13) it was christened an F4U-1D.

    Back to the SD. The detailing out of the fuselage sure seems to take a lot of time. I think I'm just slow. This first photo shows the left side window construction. The outer surface is 1/16" balsa and is backed up with 1/8" balsa strips. The plastic will glue to the rear of the 1/16" balsa.

    I guess my next project is to try to build a cover for the upper portion of the instrument panel which will give the right shape to the panel. Any ideas?

    Status: offline     		Ken I was thinking about your idea of gluing the center section to the fuse in order to prevent vibration. I would like to be able to remove the center section in the future if need be, so I am reluctant to use glue here. I will fit and drill the j bolt holes so that the center section fits as snug as possible, then I will disassemble and apply a rubber gasket between the pieces. Once reassembled, the rubber will compress and there should not be any vibration. I will also attach the upper windshield in such a manner that it can be unscrewed from the center section and not destroyed in the event of center section removal.

    Status: offline     		Ken, regarding the instrument panel cowl, I'm going to block one out with balsa (and whatever else needed) and then vac form one from .030 acetate. This piece is quite complex in shape and really can't be made perfectly until you have temporarily fit your windshield in order to get proper shape and position. Once I fit the windshield I will scribe out the shape of the instrument cowl.
    If done properly the instrument cowl can provide a good surface to glue your windshield to.
    Bye the way I will be adjusting my windshield so that it extends within 1 cm of the engine cowl edge. This will give it a slightly more raked appearance than on the plans but the Cowl/ windshield distance will be correct. The new cowl fits the fuse as shown on plans so I will be extending the WS forward by about 1.25".

    Status: offline     		Lee, another reason for gluing the center section down other than vibration is structural ridigity since the door removes some of the fuselage strength. With the door open, there is more than enough room to get to any internal components. However if you choose not to build a functional door, you would need to make the center section removable. Without a functional door, it would be really difficult to get to the nuts on the rear of the "J" bolts. You would have to take the top window out to do this. I really don't see how anyone can get by without a functional door. To my way of thinking the only reason that the center section would need to be removable would be for repair due to crash damage.

    It would seem to me that moving the lower front of the windshield forward 1.25" would make the front end of the plane, when viewed from the side, look a lot more odd than not having the cowl come as far back as on the full scale SD. On the plans the windshield view looks correct to me. I really don't think that the cowl not coming back far enough is going to be an item that is noticable to 99% of the people. There is a tremendous difference in building a really good looking sport scale plane (which I'm building) and a competition scale plane.

    How is the cowl coming? Got a photo?

    I recently ordered 2ea 5 meter rolls of white Solartex from Balsa USA. I've never used used Solartex but from reading a lot about it, it seems that most people rave about it's good qualities. It's supposed to accept almost any kind of paint. White seemed best for whatever color scheme that I choose.

    Status: offline     		Ken, I like the idea of having the option of removing the center section if I want or need to. You are correct that most work should be able to be done through the door but the more options I have the better. I agree that gluing will offer additional strength but the wires and j bolts are designed to take the load in combination with the wing struts. If your wires fail, your glue won't mean squat.
    I may not build the functional door however I will be building in a functional left side hinged window for access and scale effect. This mod will offer me good access and take nothing away from structural integrity.
    As for the door, even if mine is not fully functional, it will look as if it is and full integrity will be intact.
    It has been clear to me for some time now that this bird can only be a sport scale model. There are too many little errors in outline for it to be anything more. I don't think extending
