    Ok my son and I may be jumping in the deep end for the ACRO II. I have been following this design from the very beginning when it came into fruition from EAA....

    1. Most of my known resources have changed or gone west.....does anyone have the current resource list for built up parts or kit components etc. that may now exists.

    a. There used to be a construction book from EAA ...where did that go?

    b. Anyone building kits now?

    c. Thinking 200hp is the right balance of power/performance the continental appears to be a simpler rebuild than the Lyc 180hp

    d. two 6ft 6 pilots or just one?

    e. What is the preferred fabric this millenium?

    Regarding point e: Ceconite or its generic equivalents (unshrunk dacron/polyester fabric), or Oratex if you're looking for something that doesn't need any paint. Oratex is a controversial choice, but it's a way to keep weight and build time down, if you can stomach the price.

    if you haven't already, you can go through all 5 pages of the build thread on mine on here. even though I built it as a single seater, it should give you an idea or two. feel free to send me a pm with your phone number and we can chat.

    Are all of these basically lighter than the old linen dope with silver and overspray?

    I'd start with Aircraft Spruce (http:///aircraftspruce.com/) and Wicks Aircraft (http://wicksaircraft.com/) if you're looking for Ceconite or its generic equivalent. You could also talk to any local businesses that do fabric work, though those can be hard to find. There don't seem to be any non-aircraft suppliers of unshrunk polyester, but the stuff from ACS or Wicks isn't breathtakingly expensive.

    I suspect the polyester is lighter than the linen, but I don't know by how much. The coatings are a similar weight as in yesteryear. Polyester is certainly more durable, and can't rot like linen can. Oratex is the lightweight alternative, but it hasn't been widely adopted, particularly in the biplane community.

    Honestly, I wouldn't get caught up with covering at this point, if you haven't started building yet. It's fun to think about, but working out your build plan and starting on that will be a better use of time. I decided to start with wing ribs on my project, since that's a relatively small task that was easy to wrap my brain around, and ribs are easy to store. Then I'll work up to building a wing panel, doing some welding and metal shaping, etc. Gradually working up to bigger and bigger tasks.

    Covering happens after everything (and I mean everything) is built and assembled and tested and rigged, which is years down the road if you're just starting out. Don't get yourself overwhelmed with choices before you need to.

    a. Don't know what happened to the book but this site is a greater value.
    b. No pre-fab parts available.
    c. 200hp is a good choice but 180 is a bit more affordable and lighter.
    d. A 6'6" pilot will have some issues in any of these designs, but there are some adjustments you can make during the build that help.
    e. Some good, proven covering systems using dacron fabric are out there. Can't get as good a cotton as you once could and linen is hard to come by.

    I'm 5'10" and I reclined my seat slightly and moved the rudder pedals as far forward as I thought I could and I fit mine, even at 240lb.

    My daughter is 5'7 and fits the front seat just fine. The pedals could easily be moved forward a bit more.

    Clay,
    Welcome to the forum. Where are you located?
    i have lots of extra Acro 2 parts.
    Smizo is the only one with wingtip molds.

    That ebay listing is one of the old covers and titles. They changed the name to "Techniques of aircraft building" or something like that. The content is the same. I think this is a very good book with not only Acro Sport info. but biplane rigging and wt. and balance and some reprints of Tony Bingelis. Good start for anybody getting into rag and tube building.

    I love mine, great choice!
    Build it light and it really performs on 200 HP.
    This site is an amazing resource, the interwebs didn't exist when I was struggling.

    You tube search "better aircraft fabric" or something like that for Oratex. Should keep you entertained for a while.

    Search "Stewart Systems" here, you tube or supercub.org. Check back in, in six months after you've digested all that.

    Search for "Polyfiber", "AirTech coatings" & "Superflite covering". There may be others.

    Pick your poison. As someone once said, they're all expensive, they all crack and none of them live up to the manufacturers claims…..

    Andrew.

    No. I'm not building anything. I'm the forum troll.
