My latest 1/2A project
« on: January 07, 2018, 11:28:41 PM »
So, this is my latest project.  Iíve been teasing the guys over on the CEF with it for a couple of weeks.  I told them if anyone correctly guessed what it will be before I posted fuselage pics, Iíd let them do the maiden flight.  Thank goodness no one has guessed yet.  If the CEF member from Finland guessed correctly, shipping would be astronomical.  Thought Iíd post an abbreviated thread here for anyone interested.  Itís pic heavy and description light.  Youíll get the idea.

Jim,

I had to look that one up.  I wasnít familiar with the Anson.

Actually, itís going to be a ME-109Z using the old Cox foam wings that Cox gave out free when you bought an .049 engine:





Iím working slowly, but the weatherís still lousy here, so no hurry.

Way cool project!  H^^

In my experience (I invented those wings) they will flatten out in time unless you run a lightweight spar out to the tip. 1/16Ē vertical strip ia all that is needed. Not for strength, just shape retention.
Think S.M.A.L.L. y'all and, it's all good, CL, FF and RC!

Larry, I was initially going to run the vertical 1/8 balsa out to the tip, and splice in a horizontal 1/8 balsa stick in place of the upper 1/8 spruce, but discarded that for weight considerations.  Perhaps I'll just run the 1/16" vertical with a 1/16 horizontal to keep it from moving fore/aft.  What do you think?

The horizontal is unnecessary if you smear some slow epoxy on the spar before slipping the wings on. The wings are plenty strong by themselves. Keep the vertical in position and you are good!

Actually, a vertical grain 1/32Ē spacer would do just fine tack it a few places here and there to keep it in position. Retaining the original airfoil is all you need. Those wings are STRONG!
