I did some Google Fu research and it seems that China has almost bought up the entire market of balsa wood worldwide for Air Wind Turbines....If you go on EBAY you will final NUMEROUS Chinese selling balsa wood but no data on density.....or grain type.

I also checked Australia, UK and Canada....same difference.....

They all expect balsa prices to double a minimum over the next year.....AT A MINIMUM! and the shortages to continue into 2023.....

Also , Ecuador which produces near 90% of the worlds balsa had some major flooding earlier this year and guess where? right smack in the middle of the balsa plantations.....and then COVID-19 hit Ecuador really hard.....

it's going to get worse before it gets better.....
