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 Guys,

Well, suffice it to say that I am behind the power curve on my move down to NC!

The first impacting event was of course Hurricane Florence.  In my attempt to be prudent I went down to NC the Tuesday before the hurricane hit and grabbed all that I could airplane wise and brought it back north.  I detail the specifics in a blog post.  

Moreover, I had friends from down there that spent the week with me up north while the hurricane did its thing, so that of course slowed me down considerably on my house updating in prepping it to sell.  

Then there was Rough River 2018.  I had originally planned not to go, but Marco couldn’t fly due his Long-EZ being down for engine stuff and his buddy’s Velocity being inop on critical avionics to fly IFR in the WX that had Rough River enveloped all the way East to the Atlantic coast.  I couldn’t let him drive the 12+ hours to RR alone, so I bit the bullet and headed off to RR for the weekend, bookended of course by the aforementioned mucho driving!

I am now back in Northern Virginia, and am once again starting to work full tilt on updating and prepping my house for sale.  Weather permitting, I will return the fuselage, etc. back down to NC in the next week or two.  So, my Long-EZ build continues to be officially on hold for a good few MORE weeks at a minimum, and again possibly up to a couple MORE months.  Still, I’ll reiterate that I will make every effort possible to minimize build downtime during this transition.

Cheers
