Vortilons

Wing Vortilons

Vortilon construction is detailed in the Roncz Canard plans since they are a mandatory addition to the wings if flying the Roncz Canard.  There was a well-known Cozy accident that resulted from a main wing stall due in large measure to the pilot/builder removing the Vortilons before a test flight.  Clearly these little guys are critical to safety of flight when incorporating a Roncz Canard into the configuration.

Now, as far as classification . . . although these are specified & mandated in the Roncz canard plans (canard = Chapter 10), they clearly go on the main wings (wings = Chapter 19).  So I’m adding them here as noteworthy item, albeit I’ll leave this page “chapter-less.”

18 October 2015 Since I had a little bit of pure epoxy left over from glassing the left canard swoosh tip, I grabbed the BID scrap box and a piece of plastic to make a 4-ply BID sheet, of which I would cut out a Vortilon or two.  I laid the 4 plies of BID into a pre-preg setup and poured all the epoxy into the layup.  After heating up the pre-preg with the heat gun it flowed well enough to wet out all the epoxy.  I then put another plate on top of it and weighed it down with my heavy tool bag (pic below).

19 October 2015 — Since I had used some leftover epoxy yesterday to make a set of Vortilons, today I wrote it into the work plan to finish the set for both wings.  Here’s the 4-ply BID layup for two more sets of Vortilons.

And here are the initial two that I cut from the glass I laid up yesterday.  These are the largest of the 3 sets of Vortilons.

Project Update

Hi Folks,

I apologize for being remiss in my lack of updates, but I’ve been running with my hair on fire for the last few months to get relocated down to North Carolina, which I’m happy to report is NOW A REALITY!

Yes, that’s right, my Northern Virginia house SOLD a few weeks ago!

Moreover, I am now happy to report that I closed on my NC house that has both a 2 car garage and a large 27 x 40 ft workshop!

So I’ll be spend the next week moving in . . .  primarily upgrading the workshop before moving the equipment, tools, airplane project, etc. into it.  This includes getting a high quality epoxy paint down on the floor since the old concrete needs a good facelift.

I will then be heading out west for a few weeks to visit friends and family after a good week of getting the new house squared away.  Moreover, I don’t expect to get back onto the build until after Rough River, but from there on out I don’t foresee any major events to keep me from building!
