THEY, then should not need as much reinforcement, being stronger/Denser.

Personally I don't like BEAD foams at all !
Except for Hotwire cutting Foils that are then skinned and further reinforced.

The Lowes bead foam is strengthened with a layer of what appears to be ethylene skin
which is not practically glue-able for structural stuff. (It's slippery like milk bottles.)
It's a cheaper way for construction uses but still cheezy for models. IMHO

9mm Depron is thinner but available form

I think I am going to give the blue Dow 1/2" foam a try. Cheaper then ordering from RC foam. This stuff has a plastic film that you can peel off. Worth a shot I guess.

Personally, I hate the R-tech stuff from Home depot. All the little balls of foam seem to come apart when you least expect it. I guess if you could keep the plastic film on it it would be strong enough? I always use the pink Foamular from my home depot with great results. Cuts and sands like a dream. My 51" WS 3D planes run at about 3.2 lbs. AUW.

Both these planes were made from the 1/2" Pink Foamular IS and fly great.

For reference sake:

Foamular and Dow's blue foam are XPS or Extruded Polystyrene. Far superior IMHO for building planes. (I use 100% fast drying white gorilla glue to build with this foam and it sands and holds great. I do use a bit of water to get the foaming action to fill cracks. Less water if I don't want it to foam and fill)

R-Tech (white ball foam) is EPS or Expanded Polystyrene. I bought this to try when Home Depot ran out of Pink stuff and its a nightmare to work with. Balls of foam everywhere and breaks way too ez....

@Pylot2b... I think you will like building and flying machines with the Dow 1/2" blue foam!!! Bring the gorilla glue to the field in case you crash and break pieces. You can literally fix most foam breaks and re-fly in 15 minutes!

I use that same gorilla glue. Under $5 for the 2 oz bottles.

Has anyone noticed the change in both Dow and OC XPS foam ?

It used to be a bit stiffer, maybe denser but in the last few yrs it's all changed
over to a softer feeling with less apparent "cellular structure" or maybe just
much smaller cells. foamy vs bubbles.

It's gotta be some environmental thang I expect as I have seen lots of
govt regulations and studies regarding new OC plants.

Depron is XPS too.
I think I heard that it comes from Holland and is used in EU for sub floor insulation.

Really like this one also.
Especially the five gallon bucket lids for the wheels, fantastic!

Unfamiliar with the tlar method. Just took a 3 view from google and laid out the biggest plane I could and still get it into a std sedan.
