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’m back on the beat with getting some airplane tasks (not build), hangar organization, NC move loads (mainly LEZ and shop toolsand starting back up again with house repairs to get it on the market.

As I communicated in my last few updates, I’ve had a fair number of significant schedule derailments over the past 6 months so I’m now really ready to get all this stuff knocked out and down to NC ASAP.  

You may have noted that I didn’t mention instrument flying training in the above list.  I am leaving that OFF the list until the house is done and on the market.  Just too many distractions and too much required mentally, time-wise and study-wise to try a concurrent attempt at house prepping and instrument flying.  At this point, the house is the definite priority as I do some sideline tasks for the Long-EZ project (instrument panel design, component CAD designs, 3D printing models/parts, etc.) that I can check, confirm & update with each trip down to the hangar.

I’m still moving out as best possible to get this way-protracted move complete and get back on the build!
