How do you plan to remove that foam from your paint?

I’m assuming that’s a special laminar surface treatment. Is there a patent?

What does that foam weigh?

I knew that somebody would like that picture. I will need to spend a lot of time sanding and cutting, before this project will look like real thing. But general shape already here, so hard part is over.

We will find out after I shape it in to something I like. Will need to do weight and balance anyway to find out how heavy ballast will be needed for CG to be at 30% or so.What does that foam weigh?

I have this question in my head for some time about compensation for right rudder. Wondering if I can add 1/2 of symmetrical airfoil to my vertical stabilizer. Wondering if people do this instead of changing angle. This piece can be CNC made from foam with different thickness to try it out until correct one found. 1/2 of 6% or 8% airfoil can be used to start with.

My answer arrived from Russia. I was told to make sure to install it on correct side of vertical stabilizer. Also left side can get 8% or 10% airfoil and right side 6%. Aerodynamically this will be better approach.

Last week I was flying Champ again with our local instructor. This time I was paying extra attention to this airplane. And yes, at 80-85 MPH this 4412 wing is definitely level to horizon in level flight and 2 people (1200 lb).

Something I don't ever see on my Skyboy solo and more power with only 1000 lb. We talked about this many times before. Drag is my enemy. I know.

My question is different this time. I talked many times about same 4412 wing and 60" chord on Aeronca and Skyboy. But on Champ ribs spacing about 12-14", and on my Skyboy about 20-22".

Wondering if this has any aerodynamic effect at all, at speeds below 100 MPH? Thank you!

Since the wheel pants move with the wheel, I think this is not easy.

are you "right handed" ?
