    Very nice cliff a bit daunting wouldn't you say but they affect is well worth the effort good to see you again!! Used to do that same thing years ago but now I have learned since then is that I use 16th balsa sheet and overlay then on my beginning edge and ending edge I send to taper in flush so that it is not raised higher than everything else the finished effect works out wonderful for me. I especially use it on my world war II aircraft peace my friend God bless ✌️🍻

    Inflling gets easier with practice. Use balsa filler to fill gaps. Beveling edges helps on curved sections. Don't infill rear of fuselage for electric RC models, it will make model more tail heavy requiring more nose ballast for flight. Use sandable wood glue like Titebond. CYA glue does not sand easily. For rubber powered free flight models, infilling increases total weight/wing loading, hurts flight performance.

    • @CliffHarveyRCPlanes
      @CliffHarveyRCPlanes  2 роки тому +1

      Hi Gary, thanks for your input, you're quite correct about infilling behind the cg for rc models (as well as rubber ff). Infilling in front of the cg helps more than it hinders if you think you're going to need noseweight, which is most of the time, cheers.

    Nice tutorial. I think this would really work well in turning a Guillows kit into a nice static model, especially their larger kits like the Mustang, Corsair, Spitfire ect. Your Bird Dog is looking very nice too.

    Hi Cliff, I lay the balsa over the gap I want to infill then I use a pin to score a mark on the balsa from the inside of the model. That way I can cut the balsa to shape as those stringers follow the curve of the model my balsa infill will be curved for a flush fit. 😉
    It does take patience.

    At the moment I am doing a easy build fleet Canuck and the shape look’s a hole lot better doing this , I generally cover with mono coat or ultra coat so to get rid of low or high spots i use spackle compound sands real easy but one cant use any liquid over the top or it turn back to mud you can spray spackle compound with lacquer to h20 proof and seal it up. Spackle ( dry hall compound ) A lot of times i will replace a lot of stringers with spruce stringers

    • @CliffHarveyRCPlanes
      @CliffHarveyRCPlanes  2 роки тому +1

      Hi Tom, Spackle has become a generic term these days, but most of the lightweight fillers work well enough 👍 Replacing stringers, especially in the areas which are handled is a very good idea, sometimes I'll soak them in these areas with ca which can work quite well ☺

  • @leefoster4133
    @leefoster4133 Рік тому +1

    Never done it. But I have seen where someone used 1/32th balsa, soaked it (not sure how long), this allowed it to bend and they just glued it on. This would go around the stringers.

    @richardbrowne1217 3 роки тому +1

    I like to use 3/32"-3/16" thickness balsa on some areas. Then sand down flush and smooth. Sometime I use Titebond glue because it is sandable and I used it as filler.

    • @CliffHarveyRCPlanes
      @CliffHarveyRCPlanes  3 роки тому +1

      Thanks for the tip Richard, it did occur to me to use thicker wood on the more curved areas 👍

  • @MORCOPOLO0817
    @MORCOPOLO0817 3 роки тому

    I noticed that those Guillows kits use a heavy guage wire for the landing gear. I think that I would recommend using a smaller guage to keep the weight down.

    • @CliffHarveyRCPlanes
      @CliffHarveyRCPlanes  3 роки тому +1

      I hear what you're saying Morco but what I did was to shorten the amount of wire inside the fuselage by not going up into the fuselage as much as the plan suggested. I probably saved more weight doing this than dropping a wire size, thanks for the idea though. 👍

    Does sheeting the nose of that kit change the CG much?

    • @CliffHarveyRCPlanes
      @CliffHarveyRCPlanes  3 роки тому +1

      Hi George, it's hard to say to what extent it has an effect on the cg but suffice to say it can only help as most Guillows models need nose weight to some extent 🤔

      Use masking tape to make a pattern of the open bay that you are infilling. Place the masking tape over the open bay. Crease the masking tape (inside of the inside border of the bay with a fingernail) Trace out the crease lines with a fine tip Sharpie. Make (mark) a Sharpie dot in the top left hand corner of the pattern for orientation. Transfer the pattern on to a sheet of wood, cut outside of the lines, & transfer the orientation dot on the cut out piece of sheet. (so if you drop it while sanding, & fiddling the fit, You will know how it was cut to fit)
