In an effort to get some of you lurkers to post up I created this new section. The introduction forum is a place for you to tell us who you are and what you are building and flying. Please follow this basic format or whatever you are comfortable with posting.

Your name and little about yourself.

Model/Serial Number/Engine of your plane

Are you building, currently flying, or just interested in Avids

Any mods to your airplane that others may benefit from

Attach or post a picture of your airplane.

To attach a picture. Under the box your typing in is a section for the attachments. Just click on browse and then find the picture on your computer. Then click on the picture and finally click on attach this file.

If you want them to show up in the post as an actual picture and not a thumbnail they have to be hosted somewhere on the web with a web address to the picture.

Follow the instructions here on how to post pictures into your post. http://www.avidfoxflyers.com/index.php?showtopic=1421

Okay. I'll play along!

I'm Av8r3400 (aka Larry)

  • I am currently flying a Kitfox Model IV-1050.
  • Powered by a 80 hp Rotax 912UL
  • 72" Taper tip, Nickel inlay prop
  • (now) Grove Gear, Grove wheels and double puck brakes, 21x800x6 Aero Classic Tires (with skis in the winter!)
  • Registered as an ELSA, so I took the 16 hour class and hold the inspector's license for it

I'm also building/restoring a Model IV-1200 Classic. This also has a 912UL and will sport the same gear package. I'm planning some tail modifications that I will detail here as I get to them.

Hey Y'all, This is Turbo, aka Art.  I love to windsurf in the Columbia Gorge where I live, but there are days when there's no wind.  What to do, what to do?  Years ago I owned a 1957 Tri-Pacer.  It was lots of fun, but on long trips I found myself more interested in flying than actually getting anywhere in particular, so I'd throttle back and tool along at 2200 rpm and 85 mph indicated.  This realization lead me away from rockets like the Sonex or Quasar, and in the direction of the Avid.  I am currently in the process of buying an Avid model C, with some Mk IV features, from a fellow down in southern Oregon.  Since I haven't flown in quite awhile, I am also working on regaining my currency and getting the taildragger endorsement.  I retired from Boeing in 2012, where as an aerodynamicist,  I was one of a very few laminar flow control experts in the company.  I capped my career off with contributions towards achieving low-drag laminar flow on the empennage of the 787-9 and -10 airplanes.  Seeing a technology that I had a hand in developing over decades of R&D finally make its way onto a production airplane was for me the cat's meow!  The Avid I'm buying doesn't have cabin heat or a trim system, and looks like it needs some aerodynamic cleanup.  Unnecessary drag is wasted fuel. I've got lots of ideas to bounce off of the group.   I dream of someday going up when there's enough wind for windsurfing, and flying the Avid backwards!

Well there is no question the Avid is a bit draggy.  Undercambered wing adds a lot of drag, not sure if there is any way to get rid of that.  But any thing that improve things is a good thing.  What engine does the C model Avid that you are getting have?  JImChuk

Welcome to the forum! My Brother lives in Walla Walla and surfs the Columbia regularly. Can’t wait to see some of your drag reducing ideas on these planes because they need it!

Yeah, the undercamber likely hurts st high speeds.   (Low CL)  The undercamber typically doesn't do much for max CL anyway -LE shape is a much bigger driver.  In my experience the most fertile place for drag reduction is the engine cooling system.  Good baffeling for the radiators is absolutely key.  "My" bird has the 582 grey head, but the radiator is under the belly.  Ugh!  No easy way to get cabin heat either.  Not too keen on heat muff approach.  The cowling is the same as on the mk4, and there is an asymmetric single-radiator installation that allows a lightweight &simple cabin heat option that doesn't need to be modified for summer.   Problem is - where to find the correct radiator?  Thinking about manual cowl flaps.  Since we're limited to 95mph ias, drag reduction is about lowering fuel burn.

Hey guys, I guess it's about time I introduce myself..I have been working in europe and in the african desert as an AME for 25 years and rated on aircrafts such as the B-737 3/4/500, Saab 2000, ATR42/72, Fokker F-50, DHC-6 Twin otter, Pilatus PC-6 porter, Bae 146 / RJ85 series..I probably have forgotten a few. Anyhow I moved to Canada from Switzerland 8 years ago. In Switzerland, I finished an experimental Rutan Long ez and flew it a 100Hrs. Also had this french built wooden 1959 Wassmer WA-40 for a few years.

The idea of moving to Canada came because of my dream of flying floatplanes, ...hence the avid catalina I have brought back into the air (my wallet shrunk from the crazy idea of owning a Beaver to buying an avid I could just afford ....)

As a job I do aerial photography using drones but also the Cat....making no money but having a blast...
