Baby Ace

Yeah the one strap for the wing join just "needs" something doesn't it!
As for the main struts,..if you use the design diameters it should be ok
wouldn't you think. They did build these as a kit and of course I am just
guessing here (since I wasn't alive wayyy back then! ) but if there had
been a warping problem as "built as designed" wouldn't we have heard about
it? Not arguing with you mind you, it is a distinct possibility with "not
the right stuff" for the job. I may have to just get an old mechanix
Illustrated copy and see the changes Paul made,...heck I may like his design
as well.

Yep,
I am thinking on the lines of the cabin ace myself and I have
noticed the
wing attach. If anyone knows of a reported failure I'd sure like to
know about it. May have to see if I can get ahold of the old Mechanix
Illustrated article of Paul's as well. I think I'd be an idiot to pay
for plans from a place in Georgia or whomever, when they are public
record in any library since being published.
I imagine they have made improvements, but it comes to a point
when you
are overkilling something and just adding weight..so I am trying to
see where that fine line ends and starts I guess you could say.

Just had a look at the old magazine article. Teh strut attach points
aren't
the best design either, but they're not the worst form that period. The
wing attach points would definitely have to be redone, though. The straps
simply aren't a good idea. The 30s version also has no jury struts. If you
omit them and the main struts are of insufficient dia and thickness to
resist flexing under compression, you'll get control reversal when your
wings warp as you aply aileron! (I know someone who rebuilt a T-craft and
did exactly this). The strut attachments to the lower fuselage are OK,
though I'd alter the rear one and subsitute something closer to the front,
but the rear strap arrangement would be OK. The top fuse to wing weldments
really have to be changed, though. There wouldn't be a lot of extra
weight.
Couple of pounds, tops. Just looking at them now, though, It's hard to see
how it would be done with the cross members buched up around the wing
area.
Someone has built a replica of that airplane form original plans, though,
and you could always ask him!
Just found him, in fact...

Good luck!
