    Southern Aero; CharlieN--I'm sitting over in the corner watching intently while I still try to work out geometry for simple differential ailerons....

    I really like your ideas.

    Me too. LOL. It will give me something to try doing during down time in my 9 hour docket tomorrow.... Beats playing Candy Crush, which I've seen many do.

    Halfway point on ribs

    So a bit more than a month has gone by and I've only been able to snatch a few hours a week on the ribs. But I finally got a system down and have reached my 13th rib. Half way. They are getting...

    Courierguy, thanks for that information. I'm curious about the big bore mod you mentioned. I assume it increases horsepower. Have you figured out how much?

    Harbor Freight has a rudimentary one that works on 18 gauge steel and even thicker aluminum. C-Clamps hold things down.

    A guy could put one stick in the middle like Paul Claus's four place supercub (or the Zenith CH 750). Then the left seater could use his right hand. Simpler setup because you don't need to link two...

    Sounds like a good plan. If you have figured out your wing options, it might be good to get that stock in place too. That way, even if everything is planned out, if something interrupts fuselage...

    This is pretty much the whole truth. Don't do it to save money, but because you enjoy building. For a first time the best you can do is probably 2500-3000 hours. That's a hard full-time job for a...

    That jumped out at me too. I wonder if it was to allow for a straight run for the x-brace going to the middle longeron under the door. It does look odd compared to the other 4 place fuselages you can...

    The wood ribs look like Wag Aero ribs for a sport trainer or 2+2. The fuselge looks cub-like. I can't make out the photos on my phone very well, but I'm guessing it was a Wag project.
