Earl, check out this site, I ordered the RCM 40 kit with wood wings. There is a a twin that would be perfect for a couple of Fox .25's. I am thinking about one for two Saito .30's.

Yeah, that's why I was keen on that 25-size plane. A lot of the 40-46 planes nowadays are even big for a pedestrian 46. I have a couple of them that are classified as 50 or 46 but need a 55 or larger for decent performance. Heck, I ended up putting a Saito 91 on a 46 biplane because it is so heavy.

I probably should grab one of those 25--size Stiks before they are gone. Another use of the 40-case is a Pizza Box Flyer (PBF). There are a couple of YouTube videos out there with them installed. Really whacky!!!

The Spad to the Bone site has a lot of .15, .25 to .46 size planes http://www.spadtothebone.org/plans.html and there are a growing selection of electrics that can be converted to glow. Looking through some old magazines, .19 to .35 was very popular in the 1980's, and a .45 was considered big. Now 40% with snowmobile motors, really, are considered big.

That website always makes me drool. Especially the pattern section!!

And they say glow is dying...

Yeah, I like the Eurekaaircraft.com website. I actually bought a plane from them a while back too. I also like that twin myself.

You Fox guys think a c-case .40 ABC (Deluxe sans spinner) will fly (and 3D) a Mojo .25 with any authority? I have a HC and LC head for it and MkX carb so I can feed a bunch of nitro. I have a new one sitting here that ain't gonna sell.

Hey guys. I never had a Fox quiet or quickie muffler. I picked up one the other day and fits my 45/46. The quickie and quiet mufflers seem to look pretty much the same on the outside. Mine has a series and small screws around the perimeter of the end piece and where it attaches to the front piece. The exhaust tip is straight instead of curved like on some. Without taking it apart, is there a way to tell which I have? I tried removing the screws and they seem to be loctited in. It might take a special size flat head driver to grip the small screws just right so enough torque can be applied to break them loose for removing. I can shine a light in through the exhaust port and look up the exhaust tip and there seems to be an inner tube and I can see all the way to the front piece. It looks like there are no small holes in the inner tube unless I just can't see them from my angle. If its a quickie muffler, is it much quieter than the standard muffler?

Card, that sounds like a Quickey muffler, if so it will be the loudest muffler you ever heard. The Quiet muffler has a baffle at the very rear about 3/8" inside and you can't see through it.

I just dragged my Fox .25 out of moth balls, I used to fly it a lot on a Telemaster 20 ARF.

Fox 1980"s .25
Fuel==WildCat 10% with 18% full synthetic, go ahead bust me, I can take it
Plug===Fox Idle Bar
Prop===Bolly 9.5x6
Max rpm===11,970
Idle==a schweet, purring 2,250 and rock steady.
The 90 sized Mac's Quiet Pipe has no effect on small engines. Except to make them very quiet. The prop drowns out the exhaust. After 45 minutes run time on the full synthetic the compression still snaps.

I'm sure you will be able to do some 3D. I don't know enough if you will be able to hover and accelerate upwards from a hover. My experience with 3D flying has been with higher torque engines like 4-stroke glow and 2-stroke gas. I have not flown much with my 40 c-case engines to know enough. You might want to use a big prop with low pitch to do more 3D, not to mention that you don't want to go fast because of flutter concerns. That might push you to the low compression head, higher nitro, and big prop. JMHO. But looking at the MOJO website, the MOJO 25 is fairly light at 1.5-2.0 lbs. If you build it light, you might do ok. If you fly from grass, you could even do without the landing gear to make it even lighter.

hsukaria

good performance. Is that a lapped iron piston engine? no castor? this could get interesting...

Hobbsy

My Feedback: (102)

Yes sir, it's an iron piston, it has always been 100% reliable in flight. I just found something I had forgotten about, I have a Davis SoundMaster muffler for it.

CardFan, picture #2 are Fox Quiet mufflers, large and small.

hsukaria

Are those muffler screws soldered on or are they removable? I might try to modify one of my stock mufflers.

Hobbsy

HS, the new numbers with the Davis SoundMaster are 12,195 rpm a little lower idle at 2,150. I don't particularly like strap on mufflers but I can live with this one. The internals at clean, a little staining from it's castor days. Bearings are still perfect.

hsukaria

Nice!!! The all-synthetic fuel keeps the internals clean. I have the same experience with the engines that I run all-synth. fuel.

It's funny how getting an engine out of the box and running it can trigger memories of former days. At one time the .25 resided on a Kombat 20 from the Airplane Factory, I had a Mac's tuned pipe on it. The Kombat series would never win any beauty contests but sure were fun to fly.This is not the actual plane but one like it. I think Tim now has that Pipe.

Here's a Primo 25 with a 40FP.... they're light weight and the work real well on Swany House 25 series models. What does your Fox weigh?

The Mojo 25 is owned and built by a buddy of mine. He will sell it to me for a good price if I want it. The Fox .40 small case ABC weighs 10oz on the nuts sans muffler and prop. I have some other small engines that would work too but they're higher on my coveted list.

1QwkSport2.5r

I will have to find a light enough muffler to use and make an adapter to fit it to the Fox and get it on my test stand. I think it's worth seeing what it'll turn anyhow. I have a Fox muffler but I don't intend to use it. It's got such an obnoxious sound to it.

Hobbsy

My Feedback: (102)

They do have a bark.

1QwkSport2.5r

That's an understatement. . The FrankenFox quieted down significantly using that MVVS muffler you sent compared to the Fox B-case muffler. My buddy noticed it was a bit quieter, though it didn't make any more power on it. The MDS liner needs some modifications and so does the crank so it makes a bit more respectable power. I should find a spare crank for the .50 - the FrankenFox crank needs the inlet timing changed a little. I think a prayer is in order on that one.

The Escapade is a smaller 40 - size model; I have one. The OP said nothing about increasing performance.

I happen to still use and fly a couple of the Kombat Airmadillos. The single engine version has a Fox .45 large case engine on it. The engine flies fine and runs great too.

carddfann

I think they are removable but very tight.

carddfann

Hobbsy,
That's what I figured it was since I could see thru to the front piece meaning there was no baffle to block my view. I took a chance when I bought it because I had no time to research it before buying. What I really want is a quiet version for my 45/46. I'm going to post it for sale to get back what I paid at $30 or trade for a quiet version. This quickie muffler looks brand new. Thanks.
