TDubs74 Posted July 18, 2020 Share Posted July 18, 2020 Fun, fun, fun right off the bat. The EZ calls for a few sheets of H-250 foam. ACS no longer supplies this, and has no recommended substitute. My question is do you all know of a sub I could use. Last- a foam is listed at ACS in the correct thickness. The plans call for 16 cubic foot pounds. This shows 18. Does anyone have experience with it, or think it's a good substitute? I have looked for other suppliers non- aviation related, and have still come up short. I suppose I could contact the group that makes the Divinicell directly, but at looking for options in case its a phased out product. Any guidance will be greatly appreciated. Quote Tim W.

Voidhawk9 Posted July 18, 2020 Share Posted July 18, 2020 I couldn't get the 250 either. I did some research and determined that 200kg/m2 PVC should be adequate, so that is what I used. Near substitution is a necessity sometimes when you live half the world away from the usual suppliers, but it is 'at your own risk'. 1 Quote Aerocanard (modified) SN:ACPB-0226 (Chapter 8) Canardspeed.com (my build log and more; usually lags behind actual progress)Flight simulator (X-plane) flight model master: X-Aerodynamics (GMT+12) Link to comment Share on other sites More sharing options...

Only problem is it's the substitute that is now impossible to find. Quote Tim W. Selling RV-8 empanage kit. Gearing up for Open EZ build. The struggle is real.

TDubs74 Posted July 19, 2020 Author Share Posted July 19, 2020 Looks like the folks building Cozy's are using Last-A-Foam for the same bulkheads. Quote Tim W. Selling RV-8 empanage kit. Gearing up for Open EZ build. The struggle is real. Link to comment Share on other sites More sharing options...

TDubs74 Posted July 20, 2020 Author Share Posted July 20, 2020 Just got off the phone with a sales rep at Diab, the group that makes Divinycell. I can order direct from them. Price will probably beat out ACS. If that is the case I may order all the PVC foam from them. He is putting me in touch with the local sales rep tomorrow, so I will let you know what I find out. Good news is, I don't have to spend a month researching foam! Quote Tim W. Selling RV-8 empanage kit. Gearing up for Open EZ build. The struggle is real.

Jeff He said he could get me OEM pricing which beats out Spruce. Did not discuss any bulk discounts. As I said if the price is good enough, I will just order all PVC foam from them. Don't know if that would be considered bulk in their eyes. I will let you know what I find after I talk with the local sales rep. 1 Quote Tim W. Selling RV-8 empanage kit.

TDubs74 Posted August 4, 2020 Author Share Posted August 4, 2020 Ok. Got the breakdown. You can only get it in sheets that are 14.1 sq feet. You only need 6.7 sq ft per the plans. The cost per sheet is $280.17 plus a $55 broken carton fee, due to the fact that there are 50 sheets per carton. SO in short 335.17 for the one sheet. In response to the bulk buy question, that would be the full carton, that even with a discount would be over 12 grand for the purchase. Do not see any sort of ROI there if the only people needing .2 h-250 are the ones building Long Ez's. And at 1 sheet per build, that's a lot of new builds needed. In short it is one expensive piece of foam without shipping so don't forget to factor that in. 1 Quote Tim W. Selling RV-8 empanage kit. Gearing up for Open EZ build. The struggle is real.

At first i was against the idea of the plywood due to added weight, but I am seriously reconsidering that thought. I think the white foam they were referring to was Clark foam?? If it was, I don't think that's around anymore either. Don't quote me on that though. Quote Tim W. Selling RV-8 empanage kit. Gearing up for Open EZ build. The struggle is real.

You guys are wasting an awful lot of time and effort on this. Just use P/N 01-14400 Last-A-Foam from ACS for the bulkheads in question (IP and a couple others) and call it a day. Cheaper and available without any special ordering. 1 Quote Marc J.

Lol I figured that since you knew that COZY's were using it, and mentioned that, that the solution was clear. I didn't think it was necessary to point out that if 800 COZY's had been built with something, it was probably OK to use. 2 Quote Marc J.
