    Scale RCM 1/3 Scale Champ Build

    The left aileron is done, took longer than expected. Rather than set up the router table again, the ribs were pre-drilled for the trailing edge dowel then cut out. A 1/4" rod was inserted into the drilled hole, then the cut lines were laid out. The left wing is basically complete, still need...

    Took the left wing out tonight to my club meeting, kind of odd this old right winger taking out a left wing, but hay I married a left winger 44 years ago and we're still going strong. One of the club members ask how much does the wing weight? Didn't know so when I got home I checked and left...

    Thanks, kind of odd posting on a full scale forum. I do have some questions I hope to get answers for over there.

    Scale 1/4 Scale 148" Shrike Commander

    Have you ever tried strip planking method for sheeting? See pdf below. This is my Cherokee 140 that was redone several years ago. If I did it again I would increase the sheeting thickness by one size then sand a little more. All in all it worked well.

    I will check it out. The leading edge and wing are roughed it. It did take some time sanding the wing bow since the radius is constantly changing. Hope the second one matches the first!

    What you have is silver bearing solder, what you need is silver solder and flux. It is higher in silver content. Technically it is call silver brazing but most old timers call it silver solder, sorry for the confusion. You can buy it at the local welding supply store , your local hardware...

    After the top sheeting was dry, the wing was flipped over and the strut and jury strut fittings were installed. Then the bottom sheeting was installed in the same manner, weights were used on the main spar and leading edge. ammonia was used as well. The comment i made about National Balsa was...

    Up to this point I've been trying to keep both wing halves at the same completion level, I just realized we have a club meeting on Monday evening and hope to take one wing to the meeting for "show and tell." I'm working on the left now, I installed the top leading edge sheeting, I got the...

    Yes the retirement is working out great, I put a shift in today on the build. I did spend a few hours on the snowblower however, it hasn't ran in several years so I had to give the fuel tank a Drano treatment followed by a Muratic acid bath. Hopefully it will run tomorrow. Snow coming on...

    Not a problem, that's what these forums are for. Back to the build, I got the 1/4" balsa leading edges and the 1/4" balsa aileron trailing edges installed on both wings. I did manage to get the wing bow installed on the left wing. There are a lot of different angles going on there, I was...

    I was quite pleased with the outcome the trailing edge is straight, I didn't have to sand any of the fits. Here is a sample of the result

    The trail edges are 1/4" dowel, I plan to cover the plane with Stits fabric and I would expect the shrinking process to deform the trailing edge. I dadoed a 1/8" groove 1/8" deep on the 1/4" dowels on the tablesaw. The ends of the ribs were finished in a make shift router table. I used 1/8"...

    I completed the cabin roof section to the point where I can glue the wings together. I wanted to slide the roof section onto wing spars while gluing the root rib to ensure everything will fit, it is a little snug and will require some sanding but all in all I think it will work well. You can...

    The gear on the BUSA Cub and Super Cub is silver soldered, similar size tubing. That is why I suggested using it. Cleaning the flux is a real pain however.

    I would silver solder rather than braze.
