Title: Old superflash build
Post by Kaintuck on Nov 3rd, 2019 at 6:21am
I drew these plans 42yrs ago....never built it. Now, with electric stuff....I should be able to do a "floater" old timer! 50" wingspan with a lifting tail.
Question is, to keep it light and use a small RC outfit....do you fellows think the fuse should be of 1/4" balsa, and maybe balsa gussets at front end? Any thin sheet work?
Or built as is, please excuse the90 degree picture...maybe admin can rotate it for me....I'm technodum..... :D
Please comment....I haven't started yet.....just started buying balsa.....

Pics look properly rotated to me.  At 50" span 1/4" sq longerons should be fine.  You might be able to get away with 1/8" sq even.  If adding an electric motor you might want to fill in the first three bays at the nose with 1/16" sheet depending on where your radio gear and batteries are to be located.  You might even step up to 1/8" sheet under the heavy components...if this is going to be RC it needs to be moved to the RC section...

Marc, That is one beautiful set of plans there. All I can say is, WOW. Love the old vintage designs. Looking forward to watching this build. That short nose scares me. Built a Clancey Baby Bee once, it had a short nose. I had a brick of lead in the nose of that thing, and the battery directly below the motor. And I never really did get the CG forward to where it should have been.

Thank you Dave....this has a lifting tail, so the CG is only 1/3 the cord :-/
We will see when I get it together and start the trimming....
