Re: Tail Jig, am I doing the right?

You are off to a good start, but honestly, I'd flip the MDF over and start over. You are going to be hard pressed to get 2 identical pieces out of the existing jig. And that's really the point of the jig, to make sure the parts are the same. You don't need to glue the blocks, screws are enough (I us...

Re: offset vertical fin

Mine is offset to the right (Corvair engine)
It's not flying yet, but that distance was recommended to me by people who have many hours flying Corvair powered Pietenpols
If I find it's not right on my plane, I'll either add a trim tab or adjust the fittings.

Re: Tail Wheel weight consideration?

I know people have used those tailwheels.
I’m using a Matco t6 which is slightly
Under 5lbs.
I think the Homebuilders Tailwheel from ACS weighs around 2 or 3 pounds.
Those are without the leaf springs though.
The plans built tailwheel assembly is probably
one of the lightest ways to go.

The Verner is a lot lighter than the Rotec.
You will have to move the wing back for the W&B.
The only flying Piet I know of with the Verner has the cabane struts straight up and down and has 30 or 40 lbs of lead in the nose.

Re: Bracing for the flying strut

tbopper
The early streamlined tubing used for the lift struts had internal ribs (drawing #6) to counter buckling or vibration, so jury struts were not used. (and so, not on the plans!)
Today's tubing does not have the internal ribs so jury struts are commonly added to the lift struts.

Re: Ribs: full length and aileron ribs

Brian, that's basically right but you only need to sheet 4 of the ribs-
the 2 outboard ribs of the center section and the butt ribs of each wing panel.
The sheeting keeps adds a place to attach the fabric on the butt ribs and
keeps the ribs from deforming from the tautening of the fabric.

You can save a little headache on the leading edge by marking your rib locations on the inside of the wrap, taping those areas off and
