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,

Months ago I made a goal to try my best to get this bird done before the Rough River fly-in.  Yes, a crazy goal… but I knew it would keep me working on the plane full bore.  So much of these builds are like running a marathon… mental motivation.  As in staying motivated.  

When it was clearly obvious that I wasn’t going to make Rough River, I took a break for almost a week to head back up to the DC area to simply relax and visit friends.  Upon my return I’ve been getting some personal things done and am really just getting back into the build.

With the fuselage still inverted I’ve knocked out nearly all of the “micro” (West 410 + micro) finishing on the bottom surfaces of the airplane and the subsequent epoxy wipes ala the Corey Bird finishing method.

Within days I expect to be be diving into knocking out the main gear leg-to-fuselage interface fairings as well.

Concurrent with completing the gear fairings I plan on doing a fair amount of priming and painting on the bottom side of the bird as well.

Yep, I expect this bird to be inverted for another 2-3 weeks (ha!) before it gets flipped back upright to close out the strakes with the top skin install.

After the top strakes it will be on to the winglet/rudder install (Chapter 20).  Then engine and top cowling install, topside finish and prime/paint.
