Hi Guys. I have a fox 15 control line engine. I bought it about 10 years ago but for the life of me I can't remember exactly which engine it is. I never finished the project and have never even started it.

Sure looks like the current Fox 15 available directly from Fox or thru several distributors. Tower has a good picture here http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXG887

Fox has a long history of holding onto good designs. The 15 is as good or better than any import as long as you use the fuel Fox recommends (20% oil with more than half of that castor). These engines are still popular in the smaller CL models and we used them a lot in local racing events.
If you think the design is long in the tooth they also make the 35 stunt motor that other than some relatively minor changes is the same design they first introduced 60 or so years ago! The 35 is not a powerhouse and is picky about fuel but I have some that I have been running for over 30 years that still start by hand with only a couple flips of the prop.

Want to correct my last post... Fox makes engines as good as any of the imports in the same price range... It would not be fair to compare this engine to one of the very small production run combat or speed motors built by small European companies. But then again you could buy 3 or 4 Fox motors for less than the cost of one of the really high zoot gems....

BTW, that's the ball bearing version. They came/come in plain bearing too. I've got both BB and plain and there's not a lot of difference in power between them.

A local CL racer always claimed that a well broken in plain bearing engine was as powerful as ball bearing motor. Of course his plain bearing motors wept fuel out of the front when running so clearly there was very very little shaft contact with the broze bearing surface.

I still have an old one that I modified to run on a bladder I just put a new P/L in it last year and it just keeps going and going and yes you can't get a better .15 for the price.

Nice looking modified intake. I notice that the engine is the bushed version. Is that a standard head with the fins milled off or a replacement head?
Is that a Jr. Satan?

Yes it's stock head with the fins machined off and the model is called "Tear a Long" I got the plans on E-Bay it has a 35 inch wing span and has 289 sq in.
Thanks

I remember the combat columnist in the old Model Builder magazine claim that for .15 combat, one could spend, at the time, about $39.95 for the Fox, or get about 500 rpm more on the same size prop by spending over $120.00 for an import.
At a swap shop, found one of the later editions of the Foz baffle .15. Talking with the seller, I took a chance, even though he said he had never been able to get it to run. Paid the $2.00 he was asking, got it home, pulled the piston, reassembled the engine with the baffle and bypass port on the correct side of the engine, and had an excellent RC engine. Turns out he had been hearing how Fox engines came through with loads of machine turnings inside, had taken the engine apart to check, and had put it together wrong. Also, he hadn't found any garbage inside.
Since 1962, I've gotten a heck of a lot of flying, CL and RC, with Fox .15s, both the baffle and the Schnuerle versions.

I have purchased more than a few engines over the past 5 years where they were new but the owners had taken them apart and either rotated the cylinder or the piston or both and then could not get them to run... the best was a Tigre 46.

50+ and Bob...I got an Enya .15 with the piston and head backwards once. Ran fine after correct assembly.
