Since most of my early stunters looked half built when they were done, I ought to be able to give an opinion.
Seriously, if you tend to build light a decent Fox with a muffler should be great. If you're going to be closer to 50oz than 40oz, I'd look to something stronger. Also, in hotter southern climates you may want more. Up here in Minnesota the cold dense air can do wonders for the overweight and underpowered. Airplanes, not pilots.
An equally important question may be " what engine really runs consistantly well for YOU?". Unless weight dictates your choice, I say go with what you find user friendly. Flying is more fun than fiddling!

If weight is an issue then the magic bullet is an L&J Fox .35 (unique hemi-head, stuffer black plate, ST NVA, various details). Exactly the same form factor, same basic engine, only stronger and better.
I'm convinced from reading all the prior literature on the subject that as soon as you start putting bigger engines in the Nobler, you start screwing up the design.
My two sense.

Boris,
I currently fly an Oriental with a SilverFoxx 35 (modified Fox 35 stunt) that weighs 40 ozs. The engine provides plenty of power and is consistant as anything you could ever want with respect to run and starting. Marvin Denny (BigIron13) also runs stock (properly chosen) in his Novi IV that weighs 48 oz. Even George Aldrich ran the 35 stunt in his Nobler that weighed 48 oz (not making this one up-actually heard his account at Brodak's a few years ago) for the win in the early 50s. My latest project, a Nobler ARF, will be fitted with a stock 35 stunt. It weighs in at 39 oz, but I do not think that this will be a problem for the Fox at all. The thing that I have found with these engines is to get the right muffler (my choices are the RSM tongue or the stock muffler) and having enough oil (25%+) on board to get the engine to run right. Probably also helps to have a uniflowed tank as well to keep things the same from start to finish.
As far as props go, I have found that the APC 10x5, albeit a little heavy, seems to be a good choice of readily available props for this engine. Works for my 26 oz Super Clown as well as for my 40 oz Oriental. While I have a Brodak BY&O 10x6 on the Nobler currently, I know that I can drop back to the APC in a heartbeat with hundreds of flights of experience to know that it will be a good choice.
Good luck with your Nobler and don't rule the Fox out at all. If worse comes to worse, you can always drop in a Double Star 40 for a boost in power. Need to either enlarge the venturi or shave down the spray bar(my choice-but don't know the diameter) to get a little better airflow to the engine. Mine uses an Adamisin tongue muffler with the exhaust holes coming straight out the end (nice to know the guy that makes these as this is not the stock configuration), swings an 11x6 APC prop, burns PowerMaster GMA 10-22 fuel and currently resides in a 50 oz Sig Super Chipmunk. This combination has done well for me for the last 3 or 4 years at a number of contests.

A Fox-35 will be fine in an ARF Nobler, right up into the low 40oz range, while George A. reccomended that engine in a Nobler weighing up to 46oz! (I heard it straight from the horses mouth.)
IMHO anything more powerfull than an OS MAX-35S in a Nobler is unnecessary. I ran that engine in a Top Flite G-Nobler several years ago and LOVED it. It had an Adamisin tube muffler and a 2/4 break to die for!
Thats why my NARF has a well used 35-S, a Veco spinner and an NOS BYO 10-6. That combo should work fine and be trouble free for the life of the plane.
Next time I build a REAL Nobler I'm going to try one of the Merco/Rustlers, but only because: 1) I want to get rid of the muffler hanging out of the cowl and 2) I like the way Fanchers M/R runs in his Tucker Special.
Noblers are low tech and should probably stay that way.

IMHO, stick with the Fox up to 45 ounces - or drop a Double Star 40 in if you feel the need for more power. The engines interchange easily and either should be fine. I prefer the RSM tongue muffler unless you need more nose weight.
A Nobler with a Fox 35 is probably the closest thing we have to a sacred combination in our sport. 
Enjoy,

What about the ARF Flitestreak with a stock Fox 35?

Darryl,
To calm myself about the nose stability I put 1/2" cross grain balsa in the tank compartment between the bearers and a 1/8" 5-ply plywood doubler across the top of the area where the engine goes. Had to hog that out accomodate the engine but it ties the two mounts together in front of and behind the engine. Also took away some of the balsa I added in the tank compartment to accomodate the Round Sullivan tank that I installed. Also added triangle stock on the engine side of the firewall to the fuse sides and the 1/8" plate. Feels plenty stiff now,time will tell. Make sure that you use a well balanced prop.
I have an ARF Flitestreak that I am currently using an OS 25 FP on and it seems to have plenty of power. I also have a 20 FP that I will be trying out in there to see how it works. The Fox 35 should pull it with authority, but I have not heard much about the long term durability of the fuse with this engine. Also depending on the case, there may be a problem with the "outside burp" that might unnerve you a bit especially if the burp leads to an engine stall. I have found that the regular Tower plug without the idle bar keeps the fire lit through this though.
Good luck and have fun with the airplanes.
John
Major overkill! Two local guys are flying the Flite Streak ARF with PAW .19 diesels, and they are very "quick"; almost too fast for stunt trainers, IMO. Maybe if you ran the Fox on a 10-4 . . .

Finished my turkey, so let me offer a different view: I believe you said in your earlier post that your Nobler is the Top Flite green box kit, so it may or may not be as light as the ARF. If you're really set on the Fox 35 for the Twister, why not try the Enya 35? It's true that a Fox 35/Nobler is a famous combination, but if you have the engine, use it.
Or, why not re-drill the holes in the Twister for the Enya so you can use the Fox you have in the Nobler? Profiles get holes re-drilled all the time.
Enya's don't get mentioned much, but they are very steady, very powerful, and last forever. I have a late 40's vintage Enya 29 that's one of my best engines ever - the piston and cylinder still look great.
P.S. Your "I" in the "(I guess)" was interpreted as HTML code for italicized text, and is recognized on SSF posts when put in square brackets. It messed me up until I figured out what was going on.
Happy Thanksgiving!

I'm a little confused - I don't know if you're saying you already have those engines on those planes, or whether you're planning those combinations. As noted above, I have a soft spot for the Enya 29. The Nieuport must be a scale biplane - that's the only Nieuport I know. So, as long as you have plenty of power vs. weight, it's probably not critical. The Thunder Tiger may be a little different.
If you're really getting the TT36 reworked by Randy, you might want to pick something more "stunt competitive." You will have paid enough for it, so it probably deserves as good as you can get. A Smith TT36 (Aero Tiger?) may be the best 35/36 on the market, at least according to everybody on the forum. There are a number of modern and classic designs to pick from. I would not hesitate to put it on a Vector 40 (Smith design) for a very up-to-date combo. It is kitted by Brodak, and you can get it directly from him, or from Randy Smith, Stuka Stunt, and Virginia Hobby.
I can't give you real world experience - except for the Enya - but it's what I've read and studied. I have seen a Vector 40 kit, though, and it looks top-notch.

Another suggestion - Ambroid (especially!) and Sterling kits have become collector's items. They may fetch quite a penny on e-bay these days. For that matter, your Green Box Nobler is a collector's kit, too. However, the Nobler is still available in so many forms, I say build it, fly it, and have fun.
You are blessed to be in your quandry.

You really dont NEED a reworked Fox for a Nobler, (Though you might want to own one anyway!).
If you want a new Fox-35, I'll happily send you a Hemi-head Fox of mine, that spit the crank last week, for the cost of postage. Then you can exchange it for a new Fox-35 at half price directly from the factory. Fox will send you a better-than-adverage "Engine room" replacement for half price.
I'd do it myself but I just don't like Foxes (Even though I have a real nice one in my Brodak Nobler.).
Also, your Stuka Stunt kit is a collectors item, much too rare to build and a plane that is more suited to a really light 25 (Like a vintage Fox or OS MAX.) than the Enya which might make for a somewhat nose heavy combo.
If you want to build a kit, buy the RSM Stuka. It's only about $100.00 shipping included and has MUCH better wood.
On the other hand, If you are dying for a custom built 35, I'll happily trade you a good running, low-hour, hand built, full house, OS MAX-35S for your Stuka kit.

Hmmm ... 10 years ago? I'm not sure if you're talking about an FP or a schneurle BB. If it is a Smith rework, either one may be too much power for any of the kits you mention. The best answer is probably just to e-mail or call Randy, and ask him what he would suggest for those engines now:

I really would re-consider about building the Ambroid Stuka, at least. BIGS post above kind've confirms that. You might just try the Classifieds on this forum - no strings attached, so to speak - and see if it might sell for a big price. That way, you wouldn't have to fool with the hassle of e-bay and make a commitment.
Where do you fly? When I was growing up in Millington, there were a couple of reconized CL fields in Memphis - Audubon Park out East, and McKellar Park (I think) down south. The park on the south side had a couple of fenced in Rat Race circles. They've probably torn all that down now.

Ha, ha - come to think of it, I never thought about it either. All of them seem to have the holes on top in the ones I've seen. Since the exhaust (and oil) would eject straight down to the engine lugs if the holes were on the bottom, that would probably get pretty messy around the engine mount area.
Yes, Bartlett was on the map when I was growing up, but Frayser was the really "hot" spot. I bet that causes a laugh.

I hope it's not too late, but I think your Fox will work a lot better on the Nobler than the Twister. There is no issue with "power" with the Fox/Nobler combination, and the Fox runs MUCH better in a full-fuse airplane than it does on a profile.

Sure - there are MANY superior engines. But he *has* a Fox.
