Top Notch Cessna 195: Scale Build-along, part 3

Aug 20, 2011 No Comments by

In this installment, the Scale Squadron club members hinge the ailerons, glass the wheel pants and cover the wing.  

Since we are painting the airplane, we decided to glass the wheel pants. This is a very easy process. Requires some 3/4oz glass cloth, Pacer Finishing Resin, and an old credit card or other piece of plastic with a smooth flat edge. We lay on the cloth, drip on some resin, and spread it with the credit card. Once it all has soaked in, we simply scraped away all excess. We did this first on one side then sanded the edges off. The did the other side. The cloth worked around the edges almost flawlessly.

 

As we described before we were not happy with the rudder control arm arrangement described in the kit. This was vastly easier. We made a small arm out of brass, drilled a hole in the middle, and soldered it onto the tail wheel gear. Attached pull-pull wire (this loops all the way through so there’s no big connecters on the end) and then drill holes and inserted the wire into the fuselage. Remember this isn’t a 3D plane so we do not need huge rudder throw. Thus this arrangement will work perfectly.

 

The Cessna 195 has a very scale shape which means lots of curves. Solartex made covering these complex shapes a breeze. Notice the tape where the servo will be located. This is holding the string we inserted so that you can more easily route the servo extension through the wing.

 

 

 

 

 

 

 

The plans show using hinge tape for the ailerons. This is OK if you’re using regular iron-on covering. But we are using a painted surface which will not work. Plus we like the reliability of a fixed, glued-in hinge. So, we used hinges, installed them near the top of the surface so it acts just like a taped hinge’s movement, and we wound up with a very nice fit.

 

 

 

 

 

 

The wing tip is shaped quite nicely. However, it is a little flexible and some coverings can distort it! So, we recommend a small spar or other reinfocement for it to prevent what happened to our wing under the stress of the covering.
