Shortly before Christmas, I flew a very nice cross country around the flint hills of Kansas.  Here is a 10 minute clip of Kansas scenery, on Belite's Youtube channel.

My Aunt Frieda passed earlier this week.

Her husband, uncle Henry, gave me a glider ride when I was a young boy.

My mother has written eloquently of Frieda in her blog, Second Thoughts.

(My mother, Katie Funk Wiebe, has written professionally for about 50 years.  Many books...  many articles... many speaking engagements.   She now writes (at age 87) on her blog, and is still writing articles and books.)

Belite Aluminum Ultralight Aircraft Cabin Construction, #8

This is series #8 in our Belite Aluminum Ultralight Aircraft Cabin Construction articles.

It's back to work on the aluminum cabin for a Belite ultralight airplane!  We're going to be working on the internal details now.

BTW, your cabin should now be covered.  You'll need to take care as the cabin is worked on, in order to not tear or scratch the dacron fabric.  This is critical because you'll be slitting the fabric and mounting the landing gear center brace through the fabric.

We've taken the liberty of additionally covering our cabin  with turquoise Oracal, which is our fantastic covering method.

Our two tasks today are closely related:  we'll mount the landing gear cross brace, and we'll build and mount the control stick mount box.

There are two landing gear cross brace plates.  They look like this:

After bending each piece, and slitting the fabric on the bottom of the cabin, the pieces are inserted through the slits and riveted in place.

Two short pieces (approximately 4 1/4") of 3/4" thin wall square tubing are cut in place and clamped, as shown in the photo below.

 Now collect the three pieces of metal which comprise the control stick support box.

Box with clecos.

 Note that in the following photo, the steel pivot arm has appeared.  You'll want to check fit with it very thoroughly before riveting, as the instructions for its mounting follow!  Also note that the attachment bolt is an AN4-7 with washers and a locknut.

 So let's investigate what needs to be done to attach the steel pivot assembly.

 The control stick pivot should rotate with complete freedom.

In our continuing series of aircraft construction articles, it's time for a photo review of the cabin assembly prior to covering.

It is now time to cover the cabin assembly with dacron fabric.  Construction of the interior details of the cabin continues after you've covered the cabin assembly.
