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,

I left my last project update for a while so everyone would have a good chance to read it.  

So this is it folks!  I hope for this to be the final push from now until Rough River to get the main assembly of the aircraft completed.  That’s my goal.  Is it an aggressive timeline?!  Oh, yeah!  After Rough River, I then expect the next few months to be finalizing any leftover punch list items and the finishing & painting! 

Over the past few months I’ve had some unexpected scope creep in my build, which is all well and good because the build is THE project.  As you know I rewickered Marc Zeitlin’s new AEX system which took a fair amount of time to implement, then I had planned on knocking out a good dozen electrical related items so that I could close up the nose.  I got a bunch of those completed, but kept finding myself not being able to really close out wire runs, confirm install spacing configurations such as the pitch trim unit, etc. because I couldn’t sit in the airplane and confirm what I had dimensionally without the actual pilot’s seat in place.

This drove me to move my immediate project line of demarcation from the instrument panel, back one more bulkhead to the pilot’s seat.  I was then going to knock out the pilot’s seat area –including the thigh support & cover– but there was a glaring prerequisite to doing so: I couldn’t get the pilot’s thigh support configured & installed without the fuel lines in place!  Thus, I needed to move the project line of demarcation back one more bulkhead and knock out the thigh support sump tank to get the fuel lines run in reality without merely estimating some more with a fake, mocked up install.  

So the immediate order of battle right now is to finish the fuel sump (including configuring the majority of the back seat area), and then the pilot’s seat area. These, in turn, will allow me to finalize the configuration of the nose components. At which point I will focus on the building the nose while concurrently finalizing the wheel pants install (nope, haven’t forgot about those!). Then the canopy install will be after that.

Hang on to your hats folks, it’s about to get busy all up in here!

Cheers!
