    Wing strut location.

    What dictates whether high wings with two struts per side should have the struts attached to the fuselage at the same location on the lower longeron, versus being kept parallel and attaching to the longeron at points separated by the distance between the wing spars? It seems an option here could...

    Spencer Original Design

    We're figuring that Rocky didn't have a crash helmet and you didn't wanna go all that way in bad weather without a co-pilot.

    Fleeing the apocalypse in a small plane?

    . . . and then bomb the apocalypse. :nervous: A nod to Rockiedog2.

    Fleeing the apocalypse in a small plane?

    Why not thumb a ride with Choppergirl, and head for the clouds, and explain to her why a plumb-bob won't work for an artificial horizon.:gig:

    WANTED: Old Geezer To Build Double Eagle. DFW, TX

    Thanks Joe for the good words. I value your insights regarding changes to designs. It seems a little goes a long way. re: the lessons learned the hard way, I believe you're referring to AirVenture '14? Not so nice. I cringed when I read about the prop strike.

    WANTED: Old Geezer To Build Double Eagle. DFW, TX

    I wonder what Leonard thinks of the idea of closing the gap between the vertical stab and the horizontal stab, like some have done. I wonder if it gives more/less rudder/elevator authority, and how it affects crosswind behavior, the CG and stall speed.

    WANTED: Old Geezer To Build Double Eagle. DFW, TX

    I like the idea of a "fleet" of Eagles of any style, in honor of the designer, Leonard Milholland. I'm curious to know the state of completion of the DE fuselage you located. Hardly matters though if you go a different route.

    WANTED: Old Geezer To Build Double Eagle. DFW, TX

    I wish it could be an international effort. In this climate a Cabin Eagle would fit well.

    Maybe the next best Ultralight Engine!

    Why am I thinking about helicopter transmissions all of a sudden?

    plane 160 mile range, 2 or 4 people, grass strip landing, don't break the bank

    Something unrelated for ekimneirbo; Wile looking at your moniker I recognized the second half of it as something my brother used to use. I guess if I did the same I'd use leahcimneirbo, but I've tended toward other schemes for my usernames. I'll reserve comment on the seriousness of some of...

    Gyroscopic Controls

    Might've been smarter too - just sayin'.

    Round Tube Spars with leading edge sheet

    Since the spar is more rigid than the cladding it would have to fail first in order to overstress the skin.

    Round Tube Spars with leading edge sheet

    What's to calculate? Surely the spar strength has been calculated. The leading edge sheet is just a covering alternative to fabric.

    Round Tube Spars with leading edge sheet

    How much spanwise compression do you think it could support if it's "fastened to the ribs" and "the fabric is glued to the (trailing edge) of the leading edge sheet metal? Huh?? How far across the ground can you push a chain without it buckling?
  15. R

    Round Tube Spars with leading edge sheet

    The leading edge sheet will buckle (wrinkle) on its uppermost edge under increased Positive G's as the spar encounters bending loads. It might tear (or give way) under NEGATIVE G's.
