Hello folks,
I was looking around my ARF seeing how it is put together in case I should ever need to repair it. I have noticed that it is made with two different types of balsa-the "hard" type of balsa that the bulkheads and ribs are made of and the "soft" balsa sheeting used for the skin. My question is what is the "hard" type of balsa called? I bought a variety pack and it does not have the "hard" grade of balsa in it. Any help would be great-and a place I could buy it from would be great too.
Thanks!

balsa is graded in weight per cubic foot,contest balsa is 4-6 pound,for more imformation read this

Thanks for that site, I copied those tables out and put them in a Excel spread sheet! That way I can print them and put them in my data book!

Are you sure it is even balsa. Many ARFs use lite ply for bulkheads and internal fuselage componants.

I think some of it is Obechee
Birch for the sticks or spar sometimes, if not balsa
