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,

Well, I’m back into the flying game.  After getting all my requisite stuff out of the way (insurance, etc.), I successfully completed yet another Biennial Flight Review. I’ve flown a couple flights since then including my first instrument training flight in just a few months shy of 2 years! In discussions with 3 different flight instructors, it does look like knocking out my instrument rating might be a lot more feasible and obtainable than I initially thought. So…. I’m going to give it the good ‘ol college try.

Also as I noted previously, I’m waiting until late January to mid-Febraury before placing my house on the market. I would also like to point out that I typically don’t work on the build in a shop-based traditional sense during the winter since heating the shop to required temps is typically too exorbitant of a cost. Thus I normally work on electrical system and instrument panel stuff during the winter months.

Well, with both of those build areas being nearly completely done, I feel like I’m making a good use of time in relation to the airplane build.  I mean, I will need to actually fly it after all and I certainly wouldn’t want to head into that portion of the project with hardly any flight hours under my belt in previous 12 months!

Happy Holidays!
