Sig Kadet - Twin Otter winter project

Michael · December 26, 2020, 10:46:38 PM

Fuselage modifications started.

Upper front fuselage modification / battery hatch.

More progress ...

I took a break to 'float-fly' off the snow at TEMAC. I had four flights, and a great time!

Also there was: Andy, David, Glenn, Oscar, Kenny, Loy, Felix, and Ricky

Anyway, once I got home I did a bit more work on the model.

Michael · December 27, 2020, 09:24:32 PM

Okay, that's enough of the nose section/battery hatch, etc.

Tomorrow I attach the wing to the fuselage, and hopefully go back to work on the wing.

Michael · December 28, 2020, 09:07:33 AM

Change of plans, again.

In order to bolt the wing to the fuselage, there will not be room for a central aileron servo and the linkage. I will install outboard servos instead, and will retro-cut holes in the ribs to accomadate servo extension wires.

I have to work this morning, so hopefully I can have fun with more model building this afternoon or evening.

Michael · December 28, 2020, 07:51:55 PM

New cut-outs for the aileron servo wire extensions; wing sheeting; balsa fill (later to be drilled) for the nylon screws to mount the wing; and ready for sanding.

More progress on the wing.

It doesn't look like a Sig Kadet Mark II.

Great build!
Question: will you have asymmetric control for the right and left engine?

Thanks.

No. (No differential thrust.)

As much as I want to be be innovative, I also want to keep it simple.

Michael · December 30, 2020, 11:23:00 AM

Wing hold-down system done. Plywood glued into the fuselage, and holes drilled and tapped for ¼" nylon screws.

Michael · December 30, 2020, 11:24:51 AM

Fin and rudder are reshaped, and built up instead of (heavier) sheet balsa.

Michael · December 30, 2020, 01:59:35 PM

Elevator and stabilizer built as per instructions/plans; light and strong.

Michael · December 30, 2020, 02:00:31 PM

Hinged (not yet permanently) and sanded.

Next: More work on the fuselage.

Michael · December 30, 2020, 05:48:08 PM

All major construction is done. I still have to shape the fuselage front/nose, shape the nacelles, and start planning the radio/power-system installation.

(I bought skis for the plane.)

Looking really good @Michael . It's amazing how much progress you can make on a crappy flying day!
