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

Hey Guys,

A point of note to start, I have officially thrown my hat in the ring to be placed on the waiting list for a hangar at Michael J. Smith Field (KMRH) in Beaufort, NC.

As for the build, the prerequisite tasks for the nose are complete and I’m well into the both the nose and canopy builds.  The main nose structure is essentially complete, while the canopy is at the beginning stages.  In addition, the canopy external glass structure will be completed at a minimum before I haul the fuselage down to NC.

As I noted previously, the big change is that I have decided to hold off on building the strakes until after I’m in NC.  The current options I’m looking at –whether it be a hangar or a much larger workshop– should allow me to mount both wings before starting the strake build, which is of course a much more optimized way of building the strakes (not to mention much easier!).

Moreover, as much as it pains me to say this, I will be putting the build on hold after my next NC trip (end of June) to focus on prepping my current house to sell. Depending on what accommodations I end up with down in NC in the near term, my estimation is that I’ll be offline build-wise for a minimum of a month, and perhaps well over 2 months.  Of course I will make every effort possible to minimize build downtime.

Cheers
