Cox Conquest .40

The enclosed photos show the two different sleeves from my Conquest 40's, if anyone out there could give me more information on them it would be appreciated. Could the one with the three (3) holes be for the "speed" engine?

Generally the higher exhaust port timing is more conducive to stunt, I am not sure if that is the case here though. I am only speaking in generalities as any stunt engine I have had altered resulted in a raised exhaust port opening. The 3 intake holes is a schneurle type porting.

Pretty hard to come by engine you have there.

I am sure you know but anyway ... https://www.google.com/search?q=why+schnuerle+porting&rlz=1C1SQJL_enUS817US817&source=lnms&sa=X&ved=0ahUKEwjV54uBpcjiAhUE2FkKHegaD64Q_AUICygA&biw=1493&bih=776&dpr=1.13 https://www.google.com/search?q=why+schnuerle+porting&rlz=1C1SQJL_enUS817US817&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjSxKyCpcjiAhWQhOAKHeddAwoQ_AUIECgB&biw=1493&bih=776#imgrc=M_I-XGU3LINFGM:

QUESTION: Understand the higher exhaust port "could" be a result of the use of a tuned pipe - anybody remember if Cox used one? If that was the case (used one) - any chance someone out there has a photo of what it looked like and/or info on how long it was. I'm going to be using both engines on free flight models, the rules don't allow the use of a pipe therefore it's just one of those things I would just like to know it it was setup for one. I have not yet run them, when I do will post the results as "stock" then when I get them back with Nelson plug heads and some crankshaft rework will post those. ALSO - the interesting thing is BOTH engines came WITHOUT any gaskets = NONE!

Welcome to the Cox Engine Forum Lucky Lindy . Are you sure that your favorite Cox engine is a .061 ? Maybe the .051Medallion .

lucky.....sorry cuz I actually believe in USE  not collect.....except!!!! truly unique items

your toys sir do as you wish....but an un run COX .40 FIRE*  WOULD BE IN A HERMETICALLY SEALED DISPLAY CASE IF MINE

This is just me ...I have played with Cox engines since 1959...I have NEVER seen the Cox .40 live. I have never know anyone who actually had a Cox .40.... I might be wrong but I don't think so.... you claim to have at least two of them....IMO you are very unique....about as unique at some Cox engine that NEVER went to production....I bet Larry Renger can tell you there were less that 5 of them ever made...

*This attitude brought to you by a guy who is usually astounded by some E-Bay auction prices......yes, every now and then something goes for stupid Bucks that should not..... BUT the truly Rare and Vintage things can and do command very stratosphere prices.....if you do own 2 COX experimental .40s....I think you should maximize your investment....Simply my opinion

I don't have any "hanger queen engines" - I fly/use them all! I have no way of backing up this statement = I was told there were twelve (12) Four (4) bolt backplate Conquest .40's produced - and yes these would be two (2) of the twelve. The one with the spinner (Nelson) will go on a 788 inch Satellite, not sure at this time what model the other one will power - but they will NOT be put in any kind of case to be LOOKED at. I also fly a Dooling .60 ten fin as well as Dooling .29's - engines were made to be used - not looked at - I respect your opinion - but I own these and will use them as they were designed to do. I would make you this offer = if you wanted to have one for your collection I would sell you one for $3000.00, would even pay the shipping!!

Likewise I solidly respect you option to do as you please with YOUR property.... I am not exceptionally rich (but comfortable)
I would like to relate a anecdote or two....(you opened this door with a asking price of $3K+/-)

You admittedly have 2 of 12 EVER examples of COX high end MFG and Engineering.... there are literally ONLY 9 planet wide citizens that desire EVERY COX product ever built... and 6 of them have the means to accomplish that goal...Yes I pulled these numbers out of my butt

But I digress.... this is purely an economics, and Rare or Vintage Collectable point of view

Anecdote--- one of many.... I was born 1955... eldest of 5 kids... lived overseas a lot....we, or our parents always bought every NEW comic (DC and Marvel) from 1958 to 1974.....We literally had first edition of almost every title...from Archie to Hulk, Captain America, Superman, Iron Man, Yogi bear, Marvin the Martian,  yada yada...some were a nickel, some a dime, and some 2 bits.... much later a couple of graphic novels were like $1.59

As 5 kids, we amassed a LARGE (250 or more) cache of comics that took up a lot of room and boxes.... on one Army move, MOM decided to trash Most of the older boxes of comics.....

If you read this far, and do not understand the significance, it is a waste of my time to continue

BUT if you can appreciate the LOSS then you might understand... Dear old mom dumpstered about $200,000...Yes Virginia a complete collection of EVERY superman/Ironman/Hulk/Aquaman/Wonder Woman/ comic is indeed worth very big bucks no matter the condition

In the Army, wife and I saw Mattel Barbie Dolls show up in the post Exchange Every Christmas AS Unique AAFES* only dolls... we religiously bough everyone every year for the asking price of $7.99 to $23.99....some in the collection ar well over $2500 at auction
*Army AirForce Exchange System...known as the Post Exchange or PX

We also invested in Stivers art, Hummel, and LLardo figurines, and a LOT of Dragon crystal figurines....... I actually had to get appraisals of some of our STUFF for the USAA insurance...one of my wifes very simple Dragon with a unique colored stone is over $7500 at auction...we paid $15.99 at the Wiesbaden Post Exchange in Germany

Do not ask me how I managed to buy a 1967 Ford Mustang Shelby GT  350 Fastback, white with white interior for $1900 and then sold later for $1600....in still like new condition.... decades later to see same car on Barrets auto auction for $75,000..... or my 1951 VW bug split window for $150 ( pay day special) in 1975 sold for $250 (also a pay day special) in 1977...Barrett's auction around 1999 ( I think) ...$234,000

Of course any and all things...stuff....junk..collectables, baubles, jewelry, fast cars, mini bikes yada yada are only ever worth what somebody wants to pay....

I desperately want a El Taco Mini bike with 3.5 HP Briggs and faux Crager Mag wheels....but not for $1500~$2300

Run 'em up !! Turn 'em up !! Burn 'em up !!
I want see them go and make noise !!!
Then years from now some CEF members can say "Remember when those Conquest .40's were thrashed " all them while you can a box full off of assorted .40's for $50 or $100 bucks anytime .
Got popcorn ready !!!!!!!

What's the stats on the Cox .40? Can't seem to find them.

Interesting in finding out how much different from the Enya's.
