Top Flite DC3 82.5" wingspan

[Michael]

Left wing started.

Each rib and the spar had to be filed to fit diagonally on each other, and spars were built up from 2 pieces each.

More progress.

I've been very quiet lately (so busy) but I just wanted to say how fantastic your plane is coming together.  Good job!.. to you Michael, and everyone else who's building away.  Keep up the great work!

OK, a long stretch of work at the office is clearing, and I put a little more time into the wing.

Basic structure of outer panels are done and glued to center section. It was actually quite a bit of work.

I had wanted removable wing sections, but since there is so much going on within the wings (wires, retracts, aileron-flap and retract servos, etc.) there was little room for changes. It's a big wing, but it will fit in my SUV.

I started on the nacelles and made adjustments for mounting the electric motors.

The nacelles will hold the motors, retracts, retract servos and flap servos, plus it will have passing through it wires to the speed controls and wires from the aileron servos.

Looks magic! Great to see it coming together.

Those nacelles are going to hold quite a bit! Build them strong.

What's your glue of choice?

[Michael]

CA (thin and medium) and epoxy.

[Michael]

A few more hours on the wing installing servo rails, dihedral braces, retract braces, gussets, nacelle parts, hinge anchor blocks, etc., and then the bottom sheeting.

I can't believe you're allowed to build on Christmas Day!!!

[Michael]

Oh, is today Christmas? 

We went to a friend for a long 3-hour lunch, and now I'm back building the center-flap.

The wing has a 3-section flap, and each section is built up with ribs and all kinds of little bits.
The center-flap bottom sheet (about 2" x 20") is built up from 2 different sheets of balsa and one of ply; lots of work, but fun!

I'll have to stop soon for supper and an evening with other friends, and when I finally get them out of the way, I'll get back to my flaps!

[Michael]

3 (split) flap sections hinged (but not glued) in place, and flap servos and hatches installed.

[Papa]

Very neat looking work. How does it work with 3 sections and two servos?

[Michael]

Sections are joined by a loose wire inside secured brass tubes.
