I know that there are some new production parts available from cox international, (don't know if they are others too) but why there are no cylinders and pistons or crankcases in production? Are the original tools and equipment available somewhere?
Just wondering if a 100% original cox engine can be manufactured again.

All pistons and cylinders are OEM in Cox International and EX Model Engines. Most .049 tanked Bee parts are OEM, including Bee crankcase. Several parts like as needle valve, backplates, TD crankcase and fuel tanks are current production, but they also are OEM because manufactured from original Cox technical drawings.

Most available parts are NOS (new old stock). History is available and as such I won't go into detail, so may dates are approximate and not to be taken verbatim. Estes Industries, the model rocket company bought the Cox engine division from is parent company some time in the mid 1990's. They manufactured few new parts from what I understand, relying on stockpiled parts from the old Cox company to assemble new engines.

When Estes was going under, Cox International, Ex Engines and a few others bought the remaining inventory some time in the mid 2000's. The demand for Cox engines is not as high as it was 40 years ago. Bernie at Cox International has been taking existing Sure Start cylinders and converting them to Tee Dee by sending them to a machinist to have the exhaust port lower portion removed to restore SPI (sub-port injection) and remove the center web between the 2 slits.

They are not originals but are the best equivalents today, and what I have heard they are very decent performers.

There are trade offs in these type limited production runs. One is, will there be enough buyers as machining is very expensive in smaller quantities. Usually these companies want minimal quantities in the thousands, to be able to machine them at a price low enough that engine lovers will purchase them. Will they be able to sell that large amount? Unsold inventory is money tied up.

So, you probably will not see new major engine parts unless the demand worldwide is great enough to make it worthwhile to do. The demand isn't there, IMO.

There are no new engines simply because times have changed. When model engines were in their heyday, there were no computers, video games or social media (or rap for that matter).

So the younger generation has many other things they can spend their spare time on.

Is it right?

We really can't say, but it is the new reality.

For everyone's info, we recently received two pallets of Cox items (and other brands)

- About 200 NIB Cox engines from 010 to 09, including a couple each of Medallion NFFS, RR1, Microfilte 010

- About 50 non-cox engines, incl diesels from the UK (Frog, DC, etc) , Holland Hornet, OK Cub, McCoy, Testors, etc

- Bags and bags of parts for 010 to 09 (sorry, no 010 or 020 cylinders)

- About 80 balsa kits, 1/2A size and upwards like Carl Goldberg, Sterling, Ace, Brodak, SIG, Dumas Top-Flite, etc

- Over 100 balsa rubber-band kits

- About 300 static display plastic kits, some vintage and rare (?)

This is going to take quite some time to list; whereas we will probably be auctioning the non-Cox stuff under one of our eBay accounts.

Sorry Andras but there is simply too much merchandise to spread out and take pics. Right now it's all in boxes and bins but there is pretty well several of almost all Cox engine types in the mix.

my Two Cents There were a 5h1t-load of American I/C model engines/parts/accessories made.. back when they were being made. Related pieces often pop-up for sale on various internet auctions, where anyone can list.. and anyone can search. Then there are the hobby-specific forums/websites and their classifieds to search.. but a membership is usually required. It's almost always worth joining-up. You'll likely meet people who are knowledgeable in the subject-matter of your inquiries.

The I/C miniature-model engine's still have a favorable power:weight ratio over EPS.. (whatever scale..IMHO)

I'm obviously biased.  Smile  

Take into consideration the latest generation of 3D scanning/printing technology, making it possible to reproduce many parts who's dies/castings/molds are non-existent. The ability to clone any object for reproduction in the most efficient manner.. greatly reducing costs as compared to the original production-costs.

Awareness with today's youth is an important factor. We did this.. more than a few years ago..
