Hello all you wire guys ( and gals ).

I was looking around in the closet the other day and came across these.
Left overs from my control line days. I believe one is a Fox 35 and the
other is a Fox 19. Both were well taken care of by ME, there only owner.
They were put away back in the mid 70's. They still turn over as smoothly
as when I put them away! Since I have no idea what their worth I thought
I'd leave it up to you. Drop me a line with an offer, make it realistic, and
there yours. Iv'e got no ties to them.

I still get dizzy only it takes longer without wires!

Hi Bruce,

Looking at the picture the larger one appears to have an angled plug, and the smaller one has a bolt on venturi. That rules out the .35 Stunt, and little brother .19 Stunt. The small one may still be a .19, Duke Fox made numerous versions of .15,.19,.25,.29. etc.

My guess is that the bigger one is a .36 X, or maybe a .29. These are less desireable than the famous .35 Stunt, but are still good solid engines. I don't need any more at this time, but can tell you that at swap meets and on various forums either of these usually bring in the $20 -30 range, maybe a bit more if they are in really good shape.

Thanks for the info I think your right on the .29. The 19 says so on the side but could still be a Duke.

Bruce

I think the .19 shares the same parts as the .25 except the piston, cylinder, and head. I have both but have never compared them. Excellent engine.

Bruce,

The larger engine is either a .36 or .29. If it is the .29 it will have .29 stamped on the top of the mounting lugs on the bypass side.

I just gave the larger engine a through looking over and could find no other marking on it other then the Fox logo.
Must be a 36!

Bruce

I may be way off base here, but I was thinking the Fox .36 had a distinctive, "squared" venturi casting of the case, into which the appropriate round venturi was inserted...

Been a bunch of years, and I may be wrong tho...

i think they are worth 50 for small 75 big ,i have had ,they are good engies.i love old engies check out .snotec1@rcuniverse. and see for your self,[email protected]i bet u hate to see them go.take care

======================================
Kliff,

The Fox .36's of the combat type engine are the ones that had the squared intakes. The one in the picture, if it does not have "29" stamped on either the top or the bottom (I've seen the stamped mark in both places.) of the bypass side mounting lug, is what Fox sold as the .36 Stunt in the mid to late 1970's. I have three of them and the two that I've flown have had decent power, although not much more than the Fox .35. This was at a weight penalty over the .35 as well. It has been my experience that the .36's did well in somewhat overweight or "draggy" profiles with not so much of the famous Fox "burp" as the .35 has when mounted in the standard profile plane configuration.

They were (are) a good match for a kit built .29 to .40 size Midwest Warbird in my experience. They will do the 4-2-4 dance, but not as well as a properly run Fox .35. I finally gave up on trying to get the engine to perform like a Fox .35 and set the needle for a slow 2 cycle and adjusted airspeed and power with prop pitch. They are like the Fox .35, an iron piston/steel sleeve engine that requires a healthy dose of lubricant in the fuel, at least 25%, most, if not all (preferably), of which should be castor oil.

I have two of the RC versions of the .36, and while they seem to have lots more power than the 35s, they also seem to drink fuel like a camel drinks water after a week on the desert. Also, don't seem to idle well.

Thanks for the info Kliff,

Now if only I could pronounce where you live

Bruce

Thanks SourDough....I knew that a "square port" fit in there somewhere....just wasn't sure of where! Thanks for settin' me straight....cause ever since I made that post....I been looking EVERYwhere for some info on that engine with no luck.....I knew I rememberred a square port....but locally, seemed like I was the only one....thought I was going nutz!

Bruce,

I don't know about where Kliff lives, but to pronounce the name of the town in which I live, think of a back pack in a small boat.

OS

It was you I was refering to Sourdough. A most interesting, if not orginal town name!

Bruce
