In-Flight Display- Acryllic or Wooden Rod?

I would guess you would put one end of the rod in the model and the other end in the base and go from there

I've built up several models in "flight" using acrylic rod. What I have done is glue a piece of wood in the fuselage. In the case of a 1/144th B-52B I used a two pieces of 3/4" quarter round molding about 2.5 " long, glued them together and sanded them down until they fit inside the fuselage. This "plug" was glued with Elmers wood glue and allowed to dry for at least a week. Then, I started with a very small drill bit and drilled through the bottom of the fuselage into the "plug" at the angle I wanted. I increased the size of the bit until I reached the diameter of the acrylic rod, in this case 1/4". The trick is to get the angle of the hole in the base so that your model will appear to be level flight or, if you wish, a nose up angle. I found you must compensate for the weight of the aircraft which will allow the rod to slightly bend. Therefore, I drilled the hole in the base at an greater angle and the -52 came out in level "flight."

I normally like to display my models "in-flight". Planes are flying machines, so if you want to show them in their "natural environment" that's the way they should be displayed.
I don't like to drill holes on my models. I use 3 pieces of clear acrylic rod, glued to a base ( acrylic or other materials ) with epoxy glue. I position the rods to be in a way to balance the whole kit, then I use small balls of Blue Tack to fix the model. That way, I don't need to modify the kit with ugly holes.

Good modelling
