Not a yellow J-3 Cub (from Sig 71” span kit)
I have finished and flown this very old kit.
It spans 71” at 1/6 scale, and weighs 3.82 Lb.
Power is a very modest OS .30 four stroke.
This is far more than enough power for this model, and also has the proper scale external dimensions of the real one’s exposed R.H. cylinders.
It also needs just a drop of fuel for lots of flying fun.
I found it to be pure joy to fly!
Obviously, with its light wing loading this model is better suited to relatively calm days, and in case of a cross-wind you do need to make sure your rudder-thumb is quick and correct...
I finished it “the old way” too, with Silkspan (double and triple layers in higher stress areas) and sanding sealer, and brushed-on polyurethane paint (including all stripes and registration letters).
I even managed to reproduce the very characteristic fuselage top/fin root covering ‘fillet’ by applying the Silkspan while it was wet (and holding my breath...)
I enjoyed building this kit immensely.
There’s a good bit of ‘proper’ construction involved but nothing too complicated, and it doesn’t take very long before you actually see a very cute airplane take shape in front of you…
I strongly recommend to anyone deciding to build this kit, to obtain (and use!) a miter-sander for all those stick joints, as they really do have to be tight and accurate, and no "gap-filling adhesive” will give you the necessary strength (and low weight) if the joints are sloppy.
I may build another one (clipped wing this time?), it’s that good! My spare OS .26 Four Stroke will probably be used in it.

Nice, I'm also busy with a SIG 1/6 Cub, I'm just not doing it "Cub" but rather L4...Full cockpit, operational door latch, working scale landing gear (having that made by one of my customers), using litho plate for all the aluminium trim around the windows etc...
