Len's Czmelak "Smellyak" build
Pete Goldsmith designed this airplane primarily as a tow plane for aerotowing of both large and small scale sailplanes. The prototype is powered with a DA 150 on standard mufflers. The prototype was constructed in about 6 weeks, from drawing to test flight and since then, the Czmelak, which we all affectionally call the "Smellyak", has performed flawlessly
My Smellyak build
This build started back in the middle of the summer, this large cardboard box contains all the wood, gear and cowl to build the plane.
​
Start by gathering all the part for that particular task. Here the rudder template, ribs ( for both sides), the tailpost and caps are all ready to go.
​
Fin posts are thick balsa, well designed to help eliminate excess weight
​
Peter designed the control surfaces to be build over a pre-cut 1/64 ply template. You frame over each side of the template and the result is a strong stiff control surface or in this case the vertical fin
​
In this photo you can see how the 1/2 ribs are glued right to the ply template.
​
Flip it over and do the same on the other side
​
Here we are installing sheer webs to help support the vertical fin spar
​
Sub LE and TE are installed
