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,

Yep, I’m STILL hard at work finishing up the upgrades on my big workshop before I start back on the build.  I’ve completed the air compressor bump out concrete pad, removed the center roof beam support post and installed new longer, bigger beams that will allow me to have the Long-EZ in the workshop with wings on.

I am currently building the air compressor bump out and have bought the insulation for the shop. I’m also in the process of drawing up the electrical circuits and procuring electrical wire and components to have power connections for the compressor, welders, machining mill, and heat/AC… along with some new lights.  

A new wrinkle to my workshop upgrading tasks is that a few days ago –while it was raining– I entered the shop to find 2 (two) new lakes of water from “new” (to me) leaks in the roof.  I even measured them out and climbed on the roof to see if I could locate the offending spots. I couldn’t.  After assessing all the leaky drips, reality and acceptance finally set in that I was going to have to replace this 30+ year old “tin” roof . . . at least if I was going to have any peace of mind during large layups on say, the strakes, that the roof would remain DRIP FREE!  I have since ordered all the roof panels, materials, hardware and tools I need to redo the roof and it should all be here within the next week.  I’ll just be looking for some good weather after that!

I’m thinking by the time I finish the workshop upgrade tasks, get stuff organized and moved into the shop, it will be mid December before I’m actually back on the build (yeah, schedules always seem to slip to the right!

Needless to say I’ve still been busy in my actual move tasks as well.  Out of two storage units I have the bigger one only 2/3rds empty since it takes a bit during what little spare time I have to unbox stuff and then figure out where to put it.
