Another Mexican Cox?

That, my friend, is what's left of a Cox TD-4.

The Ancient Mark

great looking plane

Then it was Cox Mexico later on, that I guess they had rights to Jim Walker RTF parts, may have been involved with marketing in Mexico. Then came up with the Viuda Negra as a Cox product to help the people there to have an affordable one?

Oh my  goodness gracious I wish our grocery shops had sold such toys back in the 60-s!

Did that tilting engine mount had any rod interconnection with the bellcrank, or with the elevator base setting in any way, or, the pilot had to correct the elevator setting by constantly adding "up"command with his hand in e.g. the beginner's position?

That BB indeed looks to have low milage on its clock, no toolmarks anywhere, the thin wall cylinder with taper bore must be producing as-new compression..

Mark's on to something, that explains it.

András, to top that off, across the street from the first house my parents rented (a year later we moved a a block away) was a Cornet department store. It had several shelves of all the Comet rubber powered aiplane kits.

Then Bob's got a prize engine, being a TD-4 fuselage would place the engine I imagine in the late 1950's, early 1960's.

Thanks George for straightening me out on my Spanish, and Mark for ID the left-over carcus.  If I ever heard anything about the TD-4 it didn't stick.  

Went looking around.

But, That C/L handle with the blue line..........Doesn't look Cox!

Bob, you're welcome, BTW, that handle looks more like a handle for flying a kite and winder for its string, no?

Doesn't it, and only one line too.

That wing looks alot like the Baby Ringmasters wing, it will help me to duplicate.

Ringmaster wing shape is fairly universal. Short of having access to say, a TD4 designed wing, I can't see why it wouldn't do.

Hmm, I thought it was a balsa wing but looking closer, it's plastic. Leadout guides, edge reinforcements. Still, I have to make one out of balsa. If I can't clean up the blue I will have to paint it. Blue/yellow always popular sounds good.

Appears that Cox simplified the wing, done away with the thin sheet plastic halves that were vacuum formed, then welded together at the seams.

The undercambered wing would have lots of lift coupled with drag. A symmetrical wing would be a better stunter and wind handler.

If I had that fuselage, for quick building, might consider a symmetrical K-Flex wing of 3/16-in. foamboard layers with a center rib section to match fuselage saddle contour.

More than 1 way to do. Best way is the one that gets done to satisfactory completion.

You've got a rare but historic fuselage, Bob, but that early Babe Bee is a nice rare bonus prize.

That crossed my mind George, perhaps two wings, one simple balsa, the other as you describe.  Rubber band attachment makes it simple.  I doubt if I will be able to clean up that fuel damaged nose requiring paint.  I have that matte blue that I am so fond of.  Takes to plastic very well.  The nose adjustment comes off easy with a single screw.  The rest rubber bands but there may be a broken piece in the control rod structure.  

I'm pumped.  I thought I had every Cox model covered at least in print if not actually.  TD-4 hiding in plain sight, with a nod to batjac Mark.

The Been There, Done That Mark

Wow, Thanks Mark. 2014 and i forgot all about it and i even participated. Looks like I'm missing a major piece but thanks to your drawings I should be able to reproduce it.

I thought it interesting that Cox would include a girl pilot. I guess that Cox was experimenting to see what would attractt sales.

These TD's faded away I guess because they may have been too simplisitic for sales. The scale jobs seemed to be better sellers.

In Mexico where wages were lower, the simpler and cheaper to manufacture fuselages (or perhaps unsold fuselage stock from Jim Walker RTF's made the Viuda Negra (Black Widow) along with sheet balsa wing made the RTF more affordable. Plus, after its destruction they had an engine to use in a kit.

Bob, it looks like now you have the makings for you next project.

Actually, Cox was very open minded about all kids participating.  The sticker on the left was a girl pilot, the sticker on the right was a boy pilot.

Just won this on ebay.  A little different with the adjustable thrust angle that has been discussed here before.

I recently took my first dual flight in a real plane and was asking my instructor where the beginner / sport/ stunt control was but he kept looking at me funny.  Then he said he didn't want to fly with me any more. Did I do something wrong?

Experience is a hard master.

You just had an introduction to various personalities in life. He may have thought you were not serious and probably didn't know where you were coming from. Problem these days is that the aviation industry is under attack and there has been much fear mongering with the unfortunately oligarch owned mainstream news media (radio, TV, printed media, etc., plus the FAA can have a heavy hand on them affecting business. This is another topic best for the CEF Red Neck Zone.)

I'd give it a few days, then call him up or visit him, apologize and tell him where this thought came from, a hobby interest, but you intend to be a serious learner. This particular guy is a serious type and it will take a while until he really gets to know you. Then you can kid with him.

If you get nowhere there, then I would contact his supervisor (provided he isn't a supervisor) and explain to him, let him talk with the instructor or assign you another.

I know, because I've been there done that.

You did nothing wrong. Your instructor obviously has no sense of humor. And...........and had never flown a Cox TD-4.

I'm kidding guys.

Nice to find the Cox forum and get some replies re my question about my first-ever flying model that blue Cox P-39 --

Getting to know you aeronaut..............Good to see that you have a sense of humor.

No problem.

Got my share of "donor engines" from those who had those one-shot flights as a kid, including my one-shots flights.

Neat to see some of these old birds successfully fly. Before my time old enough to fly these, Cox had caged circles at Disneyland in the early 1960's, would put on demo flights for the crowds to watch. That was when old Walt was still alive, the master of good wholesome imagination.

For me, that was before the Toys-R-Us kids.
