Nostalgia Profile Carrier project
« on: April 11, 2013, 08:40:56 AM »
I plan to make another copy of my Profile Carrier "Devastator" which I flew throughout the 1975 season, including taking third place at the Lake Charles Na ts, ending with the Wichita record trials on January 27, 1976.  This is pending my securing the historic engine, a Supertiger CRC 35.   Doe anybody know a reason this would not quality for the Nostalgia bonus points?

This was built and flown in the "pre-scale" days, in other words, no scale points.  It was a Devastator in color only.

I had to crop down the magazine article to fit the limit.  I do not plan to reproduce the hair style and/or the plaid pants.

Paul, how about a set of rib templates?  This just might be a good plane for both Nostalgia and NW Sport .40. Simple, quick an d competitive. I have been toying with the idea of using Rusty Brown's "Trager". I have a Set of plans for this one, but they do not show hook installation.  Also I'm not sure about the diamond shaped airfoil either.

Big chuckle.  It looks more like an early slow combat plane.  H^^ LL~

That's pretty much what it is.  The airfoil was just a hand drawn thing with the ribs 1" and 1/16" capstrips for a total of 1-1/8".  It wasn't a diamond although my attempt at quarter scale hand drafting looks somewhat diamond-like.  It has a freehand curve in front and pretty-near straight back.  I used 1/16" x 1/8" spruce spars layed flat.  It has a lot more than the minimum of 300 squares and looked more "airplane-like" than some of the competition.  When I dig out the templates I'll post them.  

One of my problems in Profile was too light and too much lift.  So when I tipped the nose up it would rather do a wingover than stall and hover.  Under the rules of the day a 90 MPH high followed by flyng (not hovering) at 20 MPH was an OK score.

One note.  At the 1975 Nats in Lake Charles I couldn't get the engine to run right in testing durng practice two days before the event.  The problem was traced to front end vibration due to cracked engine mounts.  With the aid of my passenger, Lew Woolard, I was able to completely rebuild the front end and get it working by the day of the event.  It's hard to believe that I had the motivation to put that much effort into one event back then.

Of course it qualifies for the Historic Model bonus.  True also that there are no Scale Bonus points in Nostalgia Profile.  There is no such thing as a "Historic Engine" bonus - there is a non-shneurle engine bonus that goes to any non-schneurle engine.  The engine does NOT have to be plain-bearing or 'stock' as it did in 1975 or old.  The present day rules apply to engine eligibility.  The bonus is to put the non-schneurle's on a more equal foot.

Right.  I know.  I figured if I'm going Nostalgia I'll go all the way and make it 1975-legal with the engine of the day.

I've been using a Brodak Flying Clown with a modern OS.  It gets the airframe points but not the engine points.

I'm using an old OS III .35 with a SuperTigre Carb.  This engine used to kick A** in slow rat / sport racing when they DID have to be plain-bearing and stock.  That engine wouldn't have been legal in Profile back then because it wasn't a "Stock engine with the factory supplied carburetor".  It's the engine on the Flying Flapjack that I posted last winter.  I never got my SuperTigre C35 to run as well as everyone else was doing with them and haven't owned one since.

I won with 1970 Nats with an OS Max III RC with the factory throttle.  It was all stock as the rules required.   

Back in the day you needed a STOCK RC 36 with the factory throttle in place.  The other popular engine was the K&B Greenhead 35 RC.  A Veco coulkd have been used but it was not so popular around here.  Maybe an Enya, but I never saw one.

When they lifted the "stock engine" rule the event was overwhelmed by a few top end racing 40's, downsized to 36, bearings changed to bushngs, and sometimes lefthanded cranks.  This was a far cry from the minute treaking that slipped by unde the stock engine rule.

The stock plain bearing 36 rule worked as intended.  It got me into the event.  For those who wanted all out power there ws still the main "unlimited" class that subsequently morphed into Class I & II.  Back in the day, "US Navy Carrier" was anything at all that fit into the four-pound weight limit.

Now this...is a Devastator. Too bad it is not eligible for Nostalgia, even with a Shoestring wing. Good luck with yours Paul.  8)

Boy Paul, you bring back the memories.   I was still flying Class II Carrier in 1970.   Was my last year to attempt carrier at a NATS as i got to playing  with F2C.   Didn't build a profile until the 80's after they changed it so people could fly all three classes.   If I remember right there was over 200 entries in profile.   I still think profile should have been separate from the scale classes.   In other words you flew profile or you flew scale.  But, too late now.   The thought just hit me, how many people have we been around at different places, like NATS and contests, just to realize we didn't know each other back then.

The deal where you had to chose between Profile and Scale might have had some flaws, but it brought in a lot of new people who were not willing/able to compete with custom-machined Rossi 40's and OPS 65's.  When the separation was lifted, the machinists attacked Profile with a vengeance.

For me there was nothing to enter until "15" came among.  Now even that is soon to be electrocuted. 

With about a dozen classes on the books we have more than enough, but still no welcoming point of entry.  One good way to proling the category without increasing the event count would be to change Profile to a stock RC 25 complete with factory throttle and muffler.  The few guys who were able to get left-handed Nelson 36's 25 years ago have gotten more than their money's worth.  It's time to get into the 21 century.

I was at the 70 Glenview NATS. So many people in Carrier you could easily lose your flight if you didn,t get to the decks soon enough. Glenview 70 and 72 I think was the high water mark for carrier and I was there to enjoy it. How could have we met with so many people there. I did get to meet Roland Baltes before he suddenly passed away and saw Terry Herron fly the famous Judy. I think there were at least a dozen of us from the Cleveland area for those two NATS. Highlight of my Carrier carreer. Oh well.
Thanks

Right, Wayne.  The setup of 1970 let the Class I & II guys continue to do their high-powered thing and brought in a whole different group of newbies to fly Profile.  I don't remember a single Scale guy dropping down into Profile.  The "waiting list" style of schduling worked well.  You signed up when you were ready and then added you name to the bottom after you were done.  He who hesitates is lost.

I've still got the hair, but it's lighter to say the least.

I think the old popularity of Carrier was closely linked to Navy sponsership of the Nats.  Win or lose, Carrier flyers were the stars of the show on a Navy base.

I hit pay dirt looking for my old templates.  I found 'em without digging too deep AND realized that I built a racer with them last winter and made a spare set of ribs while I was at it.  I had visions of having to make new templates, a job I hate, but ended up not even needing to make the ribs.

The Loonie racer of 2012 isn't all that different from the 1975 carrier job.  

The ribs are 6-1/2" long with the balance of the chord being made uo by the leading edge, trailking edge, and stationary flaps.

The plywood master ribs are held together with a piece of DuBro 4/40 rod, available from The Prop Shop with both ends threaded.  The rib stack is also aligned with a bit of dope between the blanks to keep them straight.  It's not a full coat, just a few drops positioned so that most of it gets sanded off.
