After reading the very positive rating for the Fox Eagle .61 in the recent MAN engine comparo, I am looking at the Eagle .74 to put in the GP Shoestring. Have contacted Fox with some questions and am trying to get some specs, but haven't heard back from them. Is there someone out there who can answer the following :

- engine weight without muffler?
- Pitts style muffler that will fit up to the .74?
- 5% nitro recommended for breakin, can
10-15% be used for flying? Any problems?
- Fox website shows an "Easy Adjust" single
needle carb for the Eagle engines which I
guess means that it covers the entire range,
Would be great if it eliminates the low speed
valve. Do these carbs adjust well? Any
compromise in power?
- Any comments in general regarding the .74

Thanks in advance for any info. Joseph

Try the following link to FlightLine Solutions.

This site is run by a couple of Fox fans from Canada, and in my personal opinion, has more information, and is a better site, than the one Fox has itself. You should be able to find most of the answers you need there.

BTW, I used to live in Fort Smith, AR, where the Fox engines are still made, and have had a personal tour of their facility a couple of times. If you are ever in the area, I am sure they would be willing to show you around as well.

Regards,

I have a fox eagle .74 with stock muffler and a new slimline pitts style muffler. I don't know the engine weight off hand but I remember I was reading that even though the engine looks bulky it actually weighs less than a comparable .60 size. The carburetor is has high and low needles. The engine has seen only a gallon of fuel and will be in the for sale section soon.

WHY ARE YOU SELLING IT?

I have the exact same engine, a Fox Eagle IV, .74, in my Shoestring. Excellent performer. Has the Eagle IV late model, single needle carb. Has adjustable air bleed for low end. Very user friendly. I used 10% Cool Power for break in, and flying. I've got it mounted horizontaly using a Slimline Pitts muffler. You've made a good choice. I have had 4 of these Fox .74's at one time. I sold 3 of them off in excellent shape. The people in my club grabbed them because they knew that all of my engines run well.
Hope this helps. > Jim

Why am I selling it ? because I am getting into gas engines and have too many glow engines, some of them still in the box.

hey foxx. got a fox .46 for sale by any chance?


Dan

Treker, thanks for the good lead. Looked up Fliteline Solutions site, very informative! Am intrigued by these moters and think I'll try one. Do you run Foxes? Any comments?Planning to ride my Beemer back to Oshkosh in July and will swing thru Fort Smith for a tour.

Sorry Dan no .46 but I give a good deal on 74.

Gee Bee Jim, Saw your post on one of the Shoestring threads and have been trying to track
you down. No one around here is familar with the Fox engines but would like to try one. You stated they are user friendly. Is this new carb what you are referring to? Easy to adjust- Holds a setting? Any additional comments would be welcome. Pour forth for all of us. Also, which size and model slimline did you use on the .74? Any problems with mounting or backpressure? Contacted Bisson but they didn't have any specific info for this engine. I assume whichever slimline fits up to an OSFX 61 or 91 would be available with Bisson also, which I would prefer.

Joe: I'm using the SLIMLINE brand muffler for a Fox .74. I believe that they are made up around Phoenix someplace. The Eagle .74 is a very strong, and much under rated engine. They are not as highly polished as the imports, and do not wind up as tight as the imports, because they are a long stroke engine. Most people do not realize this. Hence; the Fox has big time, high torque lugging power. I run a MAS 14 x 6 on mine, and have never been dissatisfied. Service from Fox, right here in the U.S. of A., has always been outstanding.

garch 22,

I only own one Fox engine at the moment, but I would buy another if I had a need. This one is an older (early 90's) Fox .45 that I picked up on E-bay for about $60. It was new in the box when I got it, and had never been run other than what they do at the factory. It has the older style two needle carb.

I think someone else mentioned that they don't have the fit and finish that you find on most of the engines coming out of Asia. I would have to agree with that. They are a little crude in that regard.

I did have some running and reliability problems with it when I first got it, but after applying the fixes recommended on Flightline Solutions (mostly sealing up the carb for air leaks) it has been a great runner. Since it is a ringed engine, it also took some patience on the test stand to get it broken in. But now that that is done, it has been a very reliable engine. However, I sure have to put up with a lot of harrasment from the guys at the local flying field for even owning it.

I will say that to me it doesn't seem to have the power of the OS .46 FX, but I would not hesitate to install it in any .40 size plane. Right now I have it set aside waiting for a new home, as I sold the plane I had it in (a kit built GP Big Stick 40). I have an old Birdi RCM Trainer 40 kit that I think it will go with nicely. Might even put it on floats.

Later,

Anyone interested in a Fox .74, make sure to get the Eagle IV model, with their latest air bleed Carb. The Fox air bleed Carb, is the key to making these engines a top notch performer.

It's great to fly a Fox engine with a big grin on your face while OS guys land every thirty seconds to retune their needles. I love it.

Hobbsy, are you using the new Eagle IV carbs or the older dual needle ones? Do you have any comments on either?

I have both, the airbleed carb is better, it has a metering slot in it so the barrel does not slide in and out as the barrel rotates. I use a filter since the fuel metering slot is very fine and could clog easily but never has. I use a .40 sized Irvine JetStream carb on my Dieselized Fox .74, it has a fat spray bar and offers more fuel draw at Diesel rpm, plus with that carb I can run it wide open.

i didnt think this new carb was out yet for the .74

Fox service and people are really Great!

Break it in right and it will be your favorite engine..
