Combination of poor packing and USPS handling, but I have received worse, much worse.

One end of box left open and not properly sealed, happened to be the spot that got hit. When the fuselage got pushed one of the four fuselage locating pins caught the fuselage and cracked it.

At least it doesn't look like the wing got crumpled, I'm not sure what is worse, Ebay sellers packaging, or the USPS handlers. Sad

Thanks guys, I think I can make the crack less obvious, the wing thankfully is fine.

The TD3 is due to be shipped tomorrow. The seller was going away for a week and asked if that would be ok. I just contacted him with those pictures aksing him to ship UPS or Fedex and pack it well. Got a box and accessories to pack too. Fingers crossed.

That’s too bad on the shipping damage Bob…. I’m sure you can repair the fuse crack from the inside and make it near invisible…Looks like it nearly wanted to get into the canopy as well…. Luckily not… Looking forward to the magic to be worked on this nice early Cox example Small Cox Logo Small Cox Logo Small Cox Logo

Thanks Andras, glory goes to the Testors Red Tube it has pulled my bacon out of the fire many times.  

Reason for the black electrical tape - one cowling screw was missing, no cracks.

I was worried about that electrical tape, a cracked cowling is difficult to repair.  

My theory is that he flew it and broke the original Cox propeller and separated the cowl at the seam.  Took it apart and lost one of the cowl screws and taped it back together.  Replaced the propeller with the wooden one and flew it several more times which filled the open screw hole with castor goo.  Took a toothpick and alcohol to dig it out.  At first I thought the screw had broken off in the hole, not a good thing...........

Lot's to discover about this model.

From my other post.

USPS delivers Cox TD-1 bent and cracked. P1015922

Scary, thought an adult.  Back to kid.  Who would fly it like this....

USPS delivers Cox TD-1 bent and cracked. P1015923

Offset engine.  Firewall has to be a weak point.

USPS delivers Cox TD-1 bent and cracked. P1015924
USPS delivers Cox TD-1 bent and cracked. P1015925

Lead in there.  Four little 2/56's and nuts.  (Two sets were missing, flew with two loose mounting hardware? Probably not but it's how it came) Think of the labor involved.  Later models just screwed into plastic with self tappers.

Even scarier, I think that is the factory leadout termination. It looks the same as on this TD-3 that recently came into my hands.

Nice job of repair, Bob, on the fuselage crack. Yes, I'd say what you have is a quality Cox work. I'd be interested to listen to your take with your hands on experiences and research.

My gut level feeling was Leroy Cox wanted to make his planes affordable to not just the middle class, but the average Joe working parent also.

Thus, plastic injection molding, self tapping screws, simplified fuselage structure with minimal parts and quick assembly were goals.

The competition Testor's F4U Corsair, greatly simplified with Wen Mac engine is another example

I am amazed at the way they achieved their goals. A.C. Gilbert lost out because he focused on quality versus pricing point. IMO, no doubts if his American Flyer aircraft could sell for less than Cox or Testor, would have maybe had a chance in the market.

USPS delivers Cox TD-1 bent and cracked. P1015928

From the AMA text:

The Space Bug engine was quite a remarkable advance in engine design. It had a compact cast
aluminum crankcase fastened to a rather large cast aluminum gas tank. The tank held a reedvalve fuel induction system and was radial-mounted to the firewall by four screws. The pistonconnecting rod was ball and socket rather than having a wrist pin. The most amazing feature was
the steel cylinder-piston combo that was machined to fantastically close tolerances. Instead of a
glow plug, it had an aluminum glow head with a built-in glow coil of his design.


By 1953, he was selling three different versions of the Thimble Drome engine. The Space Bug
sold for $6.95. By demand, the heavy tank was removed for the modelers and it was called the
Thermal Hopper for $6.95. Then Space Bug Junior with a plastic tank for $3.95. The first engine
review in Model Airplane News magazine was in May 1953 on page 29. This sparked a new
wave of enthusiasts.

The first plane was advertised in the August 1953 issue of Model Airplane News magazine and
called the Thimble Drome TD-1. It was a U-Control model that weighed 10 ounces, an
aluminum wing of 24-1/2-inches and the body of high impact plastic was 18-inches long. It came
completely assembled, ready to fly. For $19.95, it came with an accessory kit including Skylon
control reel, battery wires, battery connecting clip, control lines, filler hose, and finger guard in a
three-color box, plus complete instructions

Have to agree about the repair. Can't even see it after! Great job.

Do you fill the crack and 'scrape' off anything on the outside after, or just wipe off excess before it dries? I just remember using the stuff many moons ago on my plastic models I used to build. Dang I made a mess everywhere.....

Easiest repair that I have ever made of this severity. A little finger manipulation and it just snapped into place. You could hear it. Then I just twisted it a bit from the inside which opened the crack and covered it with Testors wicking it into the crack. None of it came through on the outside. I just got lucky, not always my case.

Somehow I think I'm really going to screw up this wing. The aluminum is stained beyond the hot castor. I'm going to try Berrymans, it works wonders on Cox aluminum cases returning them to like-new condition. Maybe the same for the wing.

The bell crank and leadouts are all self contained inside the wing, something goes wrong and there is no repair. The pivot for the bell crank is one of the fuselage locating pins and the wing is crimp sealed all the way around the perimeter.

Throwing away caution - "If it works, it works if it doesn't, it doesn't" I coated one half of the wing with Berryman's and let it sit for about seven minutes.  Sprayed it with Simple Green to neutralize the Berrymans and immersed it in water wiping it with a microfiber towel while still wet.  I was amazed, gave me the as manufactured look that I wanted.  Finished the rest of the wing and the landing gear in the same way.

Had a feeling the Berryman's might work, wasn't sure the best way to accomplish the application, but it looks like you nailed it! That stuff sure does a good job on aluminum engine parts, the trick I learned the hard way is to not let it soak too long.

Thanks Don for the suggestion, it really hadn't crossed my mind until you mentioned it.   Then I remembered how well it works on Cox cases.  It's the best part of the model and the part that worried me the most.  Completed except for the propeller, I haven't settled on that one yet.

Wing is clean and universal in apperance, what you see are reflections.  The wing is just as it came out of the Berrymans, Simple Green, and water rinse, no polishes.

The seller refunded me $50, what I had asked for.  I told him to go to the local post office and file a claim using my description and pictures.  Makes the cost for it less than $100.

Missing cowl screw was a 2/56.  I just cut another one to length.

Hi Bob, a little acrylic gloss clear varnish on canopy crack will be good. Crack also need to be filled. I meant Testors plastic model acrylics.
