    Ok sounds like a plan. Just scetch up on some paper what you want with some key diminsions and I will get started on it. To draw just a fuse shouldn't take too long.

    Working on sheer webbing. This is the detail around the wing tube. The tube phenolic is laid out so there is just enough room for the 1/16" sheer web fits in tightly between them. Then I used a piece of 1/4" tristock and glued it down in it as well. This ties the tube back into the sheer webs and main spars and make one really strong assembly. I screwed up on the one pictured and just glued it with wood glue and I meant to use epoxy. Oh well the rest will be done correctly.

    From the dimension you gave I have to agree with you 100%. My Pro 260 new that ratio that I asked for was just under 26% when I add 4inch to the fuselage of the Pro 260 it ended up at 29% which is exactly the same as your ratio, and the Pro is flying much better and the balance is also better so every thing coming together and making sense.

    Hi @BalsaDust how is the plane coming along. Been adding up weights and it seems that it is quite difficult to not go over 7 lbs. can you please tell me what your fuselage weighs with the stabilizer and rudder but no equipment. Thanks.

    Headed to class I will weigh it all when I get home. Haven’t done much on it. Been really nice out so I have been doing a bunch of yard work before the cold sets in.

    Two questions for you what or how is the plane coming along ? Not see any progress.
    Second question I have 20cc Edge, built a little while back but did not get the chance to fly it. When completed it came out at 9bls 4 oz been looking at it and have figured that I could remove 7 oz and get the plane down to 8lbs 14 ox. I like your opinion would you take the time to do that, it will take 2 to 3 days to accomplish.

    I have made a little progress but not much as I have been more focused on the DLG I got. If you can remove 7oz I say do it. It’s still going to be anemic on power but it will be better.

    I had a feeling it was not going to be great that is probably why I did not get to fly it. Looking at an ARF it not that easy to remove weight but every bit counts I guess. 7oz is about as much as I can get out with being stupid about it thanks for the help.

    First piece of sheeting is installed. Just using wood glue so lots of clamps to keep it all flat to the ribs. Pretty happy so far. You can see in the pic where somehow I had one not line up and I think it’s just I didn’t keep the ribs square enough to the spar and it threw it off a little bit. Each wing has one that has to be moved and it’s not on the same rib in each one. Basically though though the CNC cut sheeting is really cool unless I design a jig to be cut to build the wing on to keep everything perfectly aligned I don’t think it’s worth the hassle.
