*Cox Engine of The Month* Submit your pictures! -January 2015-

Post  Admin on Sat Jan 03, 2015 1:16 am

submit the next
       COX ENGINE of the MONTH!
   and have a chance to win a Black Lynx .049 Engine from Ex Model Engines!
   CLICK HERE FOR MORE INFO
   

       Rules: You may post *one (1) picture of an engine or a group of engines that are alike (for example: a collection of Space Bug Jr.s that feature each color tank). The engine must be a Cox engine, it can be stock or parts built. Cox engines using aftermarket or handmade parts and multi-cylinder engines are allowed as long as they feature Cox made crankcase(s) and cylinder(s). Although proof isn't required, engines that are built using aftermarket or handmade parts have to be able to run. A good example of a non-running homemade engine that wouldn't qualify for this contest is found HERE.

       * You may post multiple "pictures" as long as they are all joined together in one picture. (This is done in image editing software before uploading)

MAIN POINTS
•One picture
•Picture shall be of one engine or engines that are alike (a Babe Bee and a Tee Dee .049 together would NOT qualify)
•Must be a Cox Engine
•Engines using aftermarket or handmade parts must feature Cox made crankcase(s) and cylinder(s)
•Engine must be able to run


       After 5 days, the first 10 pictures will be moved to another topic to be voted on by other members. The winner will have their engine displayed on the sidebar of the forum and forever listed on the past winners page.

       Looking forward to see what you guys come up with! Good Luck!

It is not about jealousy but one of the winners last year was a "barn find" engine in apparently disabled condition, so I wonder if the last qualification criteria above really applies? I have no problem if the engine is disabled but some clarity on the Main Points criterion is sought here...Thanks...the scrutinizing balogh

balogh, those are very well preserved Thermal Hoppers. Amazing how that almost 70 years later, there isn't too much improvement one can do to provide such a lightweight and powerful engine.

This is the field find that my son Joseph and his friend Brandon found in an open field in Gallup, New Mexico back in the 1990s. I cleaned it up and removed the corrosion with Mothers Aluminum Polish and mounted it to my saw horse bench with a new Cox glow head. A find nearly 20 years ago, it fired up right away. This earlier Cox Babe Bee will be mounted to a Sterling Beginner's P-47 my son never completed. I will finish it and present it to him some time future. (May be our 1-1/2 YO grandson Evan will enjoy it when he is old enough.  Smile ) He was amazed when I showed him photos of it.

Yes, the one on the right in my picture is a brand new pre-1955 Thermal Hopper with the small-bore glow head. It also sports a light-weight conrod with the oiling hole on the crank-pin end. The cylinder shows the fine marks of honing. Touching/watching this engine gives you the feel of true devotion by COX to what they have produced...I miss that in the commodities we buy these days...

The one on the left is a pre-owned T. Hopper from cca 1958 or so...my age, so to say...still very dependable ( I mean the engine...)

Its a new year so I thought I would rework the rules just a little and make some main points about the rules. I'll accept pictures of raw "Barn Find" engines as long as they are complete and could run if cleaned up (nothing that is missing parts or clearly damaged beyond repair). That rule was basically written to keep engines that are just thrown together and partially built or failed attempts at "homemade" engines from being entered. I good example at one of those engines would be Jason's eBay Twin

You can't go off anything that was posted in past years as the rules were revised over time. I don't like telling someone that they have to change their picture, especially if it's a really nice picture but if it doesn't feature a single model of an engine, then it can't be "Cox Engine of the Month". If you don't know if a picture will qualify or not, post it anyway. If it doesn't qualify, I'll just ask you to replace it. There are many exceptions to these rules that can be made, the moderators and I will be the judge on the entries.

Yes, you have beautifully restored this early Babe Bee, I was always wondering how the piston skirt exposed to dirt and corrosion when waiting for the finder for years survives and restores its smooth surface to save compression?

When I restarted my modeling hobby couple years ago I was hoping that - for fears the onlookers in the field may find me childish - my son will join me in this obsession for COX engines and R/C planes - which he did not -, and I can pretend in front of onlookers it is my son who plays with those small planes rather than his silverback father...a boy of the new generation, he indulges in computers rather than in mechanics...so I had to get used to the strange looks of people walking their dogs in the field where I fly my planes. And by today my only worry is the unleashed dogs walked in the filed, and not their masters. Who feels embarrassed about anything when having the pleasure of flying a COX plane??

Not sure what you mean by posted. Do you mean previously posted as a Cox Engine of the Month candidate? Or posted anywhere else previously in this forum?

I mean past Cox Engine of the Month entries. Sorry for the confusion. You can use the past entries as an example if you're looking for good picture ideas, just some things in the rules have changed over time.

Thanks, balogh. Gallup, New Mexico gets an average of 9.5 inches (0.24 m) of rain a year. When it snows or rains, due to the dry weather, it evaporates in a day or two. Relative humidity (RH) during summer is usually less than 15%. My guess is the piston and cylinder were protected by Castor oil film, which prevented it from corroding. The drier weather prevented water from doing much damage as it had less exposure than say a place that gets a lot of moisture.

Who feels embarrassed about anything when having the pleasure of flying a COX plane??
Not I, said the spider to the fly. lol!

Spider and the fly: this is what instantly occured to me:

I was just wondering if the exterior of the engine showed so much corrosion/dirt etc., the fairly delicious cylinder/piston fitting of the engine was in a clear jeopardy as well.

It may seem that way, LOL. I gather that many here have artistic abilities and know about photo composition, depth of field, lighting, etc. Cool

Apparently not as engine had decent compression and with clean up, fired up, surprising but true. One thing I noticed though is that I had to open the needle 4 turns for it to run. I'm used to about 2-1/2 turns or so.

The needle valve and seat may have developed some corrosion bulging the components thus the same fuel flow is now metered with a valve open wider than before...

1/2A Nut and TDbandit you're going to need to choose one engine from your pictures. 1/2A Nut, you have a Medallion, Tee Dee and Tee Dee .09 R/C. They're all .09s but they're all different models. TDbandit, they're both .049s and Bee type engines but they're different models.
