Thread OP

Why aren't you building with EPP?

After building a few foamies under 32inches with EPP I've had no depron or bluecor for over a year and love it.

How come you are not using EPP?

Not availalble?
Never heard of it?
Never saw a plane made of it?
Heard it is gushy?
Tried to build and it didn't work out?

You tube EPP videos:

The following videos may or may not be online:
Here is a version of the IFO in EPP:
Installing components and hinging elevons was very quick and easy.

EPP is just harder for me to get. Also, mostly it's just available in blocks, and you need to hotwire it, which I don't have. But I was going to buy some of your EPP sheets at some point. I hope you aren't closing down the shop?

I love to build with EPP, my problem is that its so much more expensive than blucor.. That said, I have a parkshark with an epp body and blucor wings and tail, im planning an STC with an epp body and bluecor wings/tail. I think the EPP body with blucor wings is the way to go, Think about it, what is the most commonly broken part of a foam model? the body... So use the expensive EPP for the body, and the cheap blucor for the wings, its the best of both worlds!

I only use EPP, bounces better than depron, I do use the study board for wings sometimes, but am finding that with the right size carbon fibre tube you can make the wings reasonably stiff. The only thing i dont like about it is that tape doesnt stick to it...

What size (for planes in the 30" WS range)?

And where do you get it?

I have a DC-3 that Gene Bond designed with a wingspan of 48" that is EPP and 3mm carbon tube reinforced (2 x 29" pieces), wings still a little flappy when pulling out of a dive, but nothing too serious. Should have used 4mm possibly.

As for my ones under 30" I use 1 x 29 inch length of 3mm rod or tube.. tube is lighter but once again I maybe should use a 4mm tube for a little more stiffness..

I get it from a few places, the LHS and a few of the online shops in New Zealand I use. Cheap and usually the only piece left that is usable except the radio gear after a few hard crash landings and dog attacks... using a dog to retieve the plane isnt ideal, tho he doesnt let it escape once he gets it.. haha

I assume you mean 'living in France' ?

Try (they are in France)
You still have to hot wire it into sheets (or wings) but the price is similar to depron.

I'd guess the main reason people don't use EPP is that they don't crash very often and prefer a stiffer material with a nicer finish. Personally I crash a lot and like EPP

I've got plenty of EPP sheets in
3mm (hollow airfoils)
6mm (curved airfoils) and
9mm (Flat 3d planes)
Please let me know how the cost compares to Bluecor and I'll see what I can do.

Thanks for all the posts!
