    Nice wing and build. A suggestion on zip ties in the wing area, they are nylon and over time in heat they will degrade and become brittle and break. I would suggest you replace them with waxed rib lacing cord. Love watching your build, its awesome.

    A bit concerned about the "up elevator" cable cutting the LE of the tailplane. Is this as per the original. I don't think leather pads will last long. A small roller would be much safer.

      Elevator cables are as per original, I might slacken them off a bit. Please remember you are seeing them in the full down deflection most of the time. It is how the designer of my kit intended it to be thanks

    • @Graff-Art

      No, look at the original drawings, the upper cable should exit just under the upper longeron. And further back compared with the lower cable. This will make it last longer.

    Hey, Scott!
    Progress! It's a wonderful word!
    When covering the wings and center section for my SE5a, I estimated the shrink length of the dacron (along the direction of the treads) was up to 1 inch per foot. In other words, each 12 inches ended up being about 11 inches (or less) after shrinking at three temperatures. Thus, over a five foot length, the fabric could shrink up to 5 inches. Apparently, the forces generated are quite large!
    This shrink rate places a lot of pressure on any straight tube that forms the outer edge of a shape, such as a rudder's leading edge (as you've found), and also on the relatively straight lower component of each wing rib. Because of this shrink effect, I added short vertical braces between the upper and lower components of all the root ribs - on the center sections and each wing panel. To prevent the upper and lower components of the root ribs from bending inwards, I used diagonal braces, as trapezoidal structures are more rigid than square ones. I made these vertical and diagonal braces like the "U" shaped intermediate ribs used on the tail feathers.
    How will you drill the holes in the wing ribs to attach the fabric? There's a lot of 'em!
    Keep it cranking forward!

      Will you make that 'window' in the upper center section?
      I elected to drill the fabric holes in the rib components before assembling the ribs to the spars for my SE5a. Here's some short RUclipss about it - I hope they work. Thinking up the process and making the jig took a while, but made drilling roughly 1300 holes much easier!

    Suggestion? get rid of the zip ties and replace with the same metal material as the cables (to prevent electrolysis ) the zip ties will breakdown over time even under covering. For those tail brackets use nuts on a threaded rod and spin in a drill against the grinder to make tube height spacers. Incidence of wings is always measured against the lateral line on a chair etc is as you sy nonsense . Tailplane 0-2degrees seems the go but You may get the correct incidence by looking at any particularly larger scale sopwith kits say 1/4 scale try google I found ""The Triplane’s tail assembly followed closely that of the Pup, in construction and profile. The adjustable tailplane employed a long leading edge with inwardraked tips; incidence range was between -2° and +2°, the usual position being +1.5°. ""

  • @curtreimer2150
    @curtreimer2150 Месяц назад

    Hi Scott, when I asked Robert about setting the angle of incidence (wing) and the decalage angle (horizontal stab) a year ago he told me this: Block the tail up until the top longerons at the sides of the cockpit are dead level fore-and-aft. Also level the plane laterally across the top longerons at the cockpit. (Many light planes are set up this way to start the rigging process.) At that point you fabricate the rear spacers on the HS to get the HS also dead level, same as the fuselage longerons. That's your decalage angle, zero degrees. The wing angle of incidence is already built in by the welded lower wing mounts. The rest of the wings (outer lower wings and top wings) should be set to match the angle of the lower wing roots so both wings will be untwisted and parallel to each other. I attached the wings, and then used a level across the spars at the root to measure the angle of incidence (around 2 degrees if I recall correctly) and then I set the rest of the wings to match this angle. At least that is my interpretation of Robert's verbal instructions. I'm also building a Camel with the steel tube fuselage. Cheers, Curt (Winnipeg, Canada)

    • @scottmatthews5280
      @scottmatthews5280  Месяц назад

      That’s the problem, he told me to put the tailplane on all four 1” spacers which sets it up at 5 degrees. Nowadays with digital levels you don’t have to block up the fuselage, you just set zero at the top longeron the measure the tail etc. I guess we will see when flying it. Have you flown yours?

    • @curtreimer2150
      @curtreimer2150 Месяц назад

      Yeah, I don't know why he gave me four equal spacers and then said to do it a different way. I ended up making my own long delrin spacers for the aft of the HS and bolting the trailing edge directly onto the fuselage weldment. I think the goal is to end up with a wing incidence of +2 degrees or so relative to the horizontal stab. At least that is in the range for most flying models and full size aircraft I have studied. The original Camel is a different airplane with a different airfoil, but if you check out the profile view on the Kiger plans you can see the HS is parallel to the cockpit top longerons. Another consideration is where you positioned the wing ribs relative to the rear spar. I positioned my spar at the midpoint (vertically) of the rib, but that puts the trailing edge lower than the spar to spar line. So the true angle of incidence will be greater than the angle measured across the bare spars. If only we were given actual plans with the kit, this would be so much easier! No, I have not flow yet. Currently working on the forward cowlings. There is a flying Airdrome Camel at my field but I'm not sure I can get any valid measurements since the wings are, of course, already covered. In any case my kit is from 2019 so who knows if he has changed the location of the various wing and tail fittings between my aircraft and yours. Best of luck going forward. She's looking good! Cheers.

    • @curtreimer2150
      @curtreimer2150 Месяц назад

      Some additional info to add to the confusion - I checked a picture I have of the flying Camel at my field and it definitely has four equal sized spacers on the HS. Mind you, this is the prototype Camel (i.e. kit #1) and has a number of differences from our production kits. I also checked a picture I took when I picked up my kit at the factory in 2019. This shows a partially built Camel and it definitely has long spacers in back and no spacers in front. I can send you this picture if you can give me an email address.

    The elevator cables over the leading edge: on upper and lower leading edges, put a low profile bracket riveted over a doily onto leading edge of stabilizer. It would have a piece of steel tubing, like brake line tubing, snugly fitting around a pin going through it, acting as a roller, that is attached between 2 ears of the bracket with double washers on each end of pin between roller and bracket. Thus, less friction (bad for cables) riding over a piece of leather that may get cut through on the first flight.

    Heads up on the tailwheel chains, they will stretch in short order. They will become loose and allow the tailwheel to float.
    As for the incidence on the horizontal stabilizer, most aircraft, they are centerline thrust of the prop and parallel. No + or - rake. I would try to get a hold of the company and ask them.

    the angle of the tailwheel caster is critical. if at the improper angle, it can make the airplane tricky to handle. So you're right about getting the tailwheel right. And how the angle changes when the suspension deflects plays into that as well.

( after fuel and everything else is in and the weight is on the tw when you do your W&B.At this point in your build you cant see what the distance is from your rudder cable end and the chains .Wait and do this last. Your allready too tight with the wheel in the air..At all up weight ( wheels on the ground) chain should be a bit slack so the rudder does the work until the springs kick in and moves the tw.

    I honestly cannot, for the life of me, see how that could be right.
    It seems a bit dodgy having the "up elevator" cables slowly sawing away at the tail plane while trying to fray themselves slowly to destruction every time they are actuated.
    I'm not being critical, just thinking it might be one of those times where it is good to take a step back and assess...
    An old aviator buddy of mine told me that most aircraft mechanical failures/crashes start months or even years before the event due to a lot of small, inconsequential-seeming assembly/maintenance/training decisions along the way that eventually cascade into failure. The devil is in the details.
