I think we are starting to see the start of the predicted shortage in balsa as wind-turbine production soaks up the available supplies - balsa is used in end-grain sheets as a core shear layer in wind turbine blades, and they don't have many alternatives.

So guard your balsa stocks - the chinese will be sending out ninja balsa-napping squads!!

Probably too heavy, klegecell, we used it in a fibreglass sandwich, great stuff to work with,, I only hope the Chinese are reading this post.

Back to the spruce, wire, and oiled silk, then.

Does this really mean no balsa, or just a hefty price increase? I reckon we can find ways around no balsa with smaller sections of spruce and ply/lite ply for most models.

It doesn't affect you though. You grow your own and have your staff manage the plantation and fell it for you.

Kryten: Sir, are you absolutely sure? It does mean changing the bulb.

As long as Aircraft Grade foam supplies don't dry up, I'm not bothered.

Why don't they just plant more trees?  ???
Electrickery is the work of the devil.
Proper aeroplanes are powered by engines.

That will provide a solution from 2027...

What about the displaced wildlife?

Planting more trees will attract more wildlife.

You mean like old hairy legged bald rough modellers ?. :''

I'll admit to all of that except the bald part!

Both, a 150% increase is predicted on what will be made available to us (if anything) for the foreseeable future, blue foam is no longer cost effective, our balsa has now been taken from us, alternatives will need to be sought and shared by us and the industry if they wish to continue.

It's a hobby lads, money will always be found for your pet fetish.

Tabsdad

Money's no use if the product isn't available, the plantations in Ecuador, (95% of the worlds' balsa production) are now in the hands of the Chinese government, they need the lot to build their turbine blades,we may get something from the Papua New Guinea producers but it will be expensive and lower quality.

The 'industry' is continuing,, it's all RTF ply structures nowadays,,

Admittedly, at the moment that's the larger part of the industry, (although there has been a shift lately) just as electric is over IC but if the existing kit manufacturers, parts producers, engine makers and plan designers decide to throw their hands in then the future is far more unstable. People are posting about the lack of LiPO availability, that's probably down to the disruption in supply chains due to Covid but we just don't know for sure, I haven't checked but I'm guessing that China has a major holding in Lithium mining and refining, allowing them to dictate the availability route of the element. All this begs the uncomfortable question of are we happy being reliant on a single source of anything being ultimately monopolised by a single nation?

IIRC our supply of balsa wood was previously threatened because of its use in LNG transport ships.

A bit ironic to hear that a green technology is now posing a similar threat.

I've got lots of Balsa wood in my spare bedroom and I haven't built a model for many years. I will keep an eye on the price of balsa and if it goes up much more I may come to market. lol
