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,  

So, I’m still working on this darn shop.  Getting much closer to kicking off getting back onto the airplane build, but still have at least a week more of shop reno to complete.

But as I mention in my latest blog post: the shop is structurally sound, but not square at all.  This makes for a timely install of both the foam insulation and the wall board over it.  It also makes every section of wall completed a huge triumph!

I had planned on setting a hard cutoff date to swap from the workshop as a priority to the airplane build being the priority, and working on the shop when I could get to it . . .

 . . . then the weather turned much chillier.

This of course means I have to get all the insulation installed to be able to keep the shop at a high enough temp to do layups.

I sincerely plan that the next time I provide a build update here that I will be telling you that the build is back on!
