Aëromodelling Detective Case File #1 - KC Free Flight


BASIC Aeromodelling couldn’t be more appropriate for the title of our 1st Case File.

Jb’s take on this article is that it is an excellent introduction to balsa (or balsawood if you prefer) and discusses its properties relevant to model builders. This article covers its history, identifies the different grains & their different applications, and gives advice for cutting and gluing.

All you need to know about Balsawood
as a novice or a seasoned Aeromodeller is presented here in this concise and well written article.

This article has several excellent Balsa Density Charts—however nowadays a more accurate and easier method is to use an online Balsa Density Calculator. You will also need a Digital Gram Scale to carry out this task. Page 27 has a chart to show you where the different densities are used. 😁 — Good Luck!

This 1st Aëromodelling Case File was searched for, located and brought to you by Renz’s Assistant Sleuth 🔎 Jb Nisley.

“Basa Wood now is the number one BASIC MATERIAL used in the construction of Stick and Tissue Model building but it wasn’t always that way.”
— Jb Nisley 2/15/2023 —

More about the history of balsawood and its relationship with model building can be found at AMA’s Webpage Aero History.
