Hi Irish. S&W is good stuff.

How are ya? How is your son-in-law?

Dick.

Capflyboy05 ,

like CGR said, you should be ok with fuel with 10-15% nitro and 20% oil in the mix. You can choose to brew it yourself or get ready-made branded fuel. The more experienced members at your club will help you select the brand. Most clubs have a fixed make / brand of fuel that everyone uses for economical reasons- they buy it in bulk at the beginning of the season. Also, if everyone uses the same fuel, the engines become uniform to tune and if there are any problems with the fuel, everyone will have the same problems together

For that reason be nice to the club president and forum moderator

morning CG- This is the 2nd drum that we have ordered from S&W and all of the members like it. My son-in-law still has his arm and it still attending PT 3 times a week. He appears to be doing well and knows that he will never have full use of the arm again. For a guy who likes to farm, this is somewhat of a setback. BUT. he still has his arm. It has not bee flying weather here from some time. Getting sim time. I have a white flying W that I flew the other day over our hay field and it was a bit overcast, almost lost it. Was very hard to see. So the flight was very short and was happy to get down in one piece.

Hey CG, sounds like the weather report says you guys are gonna get it again Wed. 10". Forget the skis, get the snowshoes.

Hey, Irish. Yeah, the weather is not very user friendly here today. But, here in the "south", Atlantic, Cape May, Salem, and Cumberland Counties, it's supposed to be mostly rain, but a switch over to all wet heavy snow tonite. We will see what that amounts to. The northern counties are getting hit hard, though. It makes quite a mess when it get to be that wet and heavy snow.

As far as S&W is concerned, well, the two hobby shops we had were carrying it exclusively, so everyone got used to using it. But, there were never any complaints, either. Now, though, with no hobby shops around, we get together and get it by the case.. by the truckload. A couple of groups, mostly the Pattern folks, buy it by the drum.

Visibility... I had a plane that had transparent wing covering... a flying wing. It was a Ripmax Rapier (google it.. neat plane). Fast as hell, and fun to fly. After the first flight, I took it home and ripped off the clear on the bottom and put something on it, I seem to recall Yellow.. that I wasn't able to see through. That thing would virtually disappear when it was up in the air with that transparent covering. And, it wasn't all that big on top of that, so the general visibility was terrible. I DO like my big planes.

Well, as as your son-in-law is concerned, I am sorry to hear that he won't get full use of his arm. That's gotta be tough, especially for an active person.

Later..

Dick.

Just to concentrate on these, the ST 15 may be either the old G20/15 or the later G15 but both most likely have a cast iron piston so I wouldn't use a fuel with less than 20% all castor. Neither of these engines are your normal run-of-the-mill sports engines and are rather collectable.

The Enya 45 is a fantastic engine but not as powerful as later engines because the 6001 model was originally intended for CL stunt. It came in two versions, the first had twin rings (like mine) then changed to a single ring in about '71. Don't use Morgan fuel (either Coolpower or Omega) in this because their fuels don't have enough oil content (only 17%). Personally I used 25% all castor in mine.

The Enya 35 has a cast iron piston and really needs 25% castor. With this type and amount of oil these engines are legendary for their life span. It's rumoured that someone managed to wear one out but no one actually believes it .

There is a huge group in New Zealand that have cut their oil content to around 12% for common .25 to 1.20 glow engines, and have experienced NO failures after many hundreds to thousands of flights. And when you think about it, visualize 3 quarts of Methanol/Nitro mix, and a full Quart of oil to make a gallon. I have always thought that that much oil was ridiculous. NO internal combustion would even run with a mix like that, (oil typically does not burn) and yeah we can go off on the "lean run" syndrom, but folks Methanol burns a hell of a lot cooler than gasoline. Hell make it 50% oil and 50% Methanol and be REAL safe.

Morgans 17% has been great for me all of these years, Ringed, ABC's, AAC's, 2-strokes, 4-strokes, YS, yada, yada...to me 17% is overkill. NOW, an old lapped Iron or Steele Piston/Sleeve may run hotter and perhaps more oil would be in order.

Just my Dos Pesos...

You can see a Thunder Tiger .46 with 380 gallons through it getting a bearing change at www.rcmodelreviews.com These guys are running around 12% oil as they have reported.

Ifly at over 7 thousand foot level and use 15% in all my glow engines.

I'm at 4'000 ft. and use 5% exclusively, works great big 2-strokes to little ones...

Hey guys!
I'm not sure where you're at,
But I'm in the Shenandoah Valley in VA.
We have about 4 in. right now.
They're still calling for another 3-6.
So I think both CG and I will need the skis AND snow shoes!
It's crazy here.
I was hoping to finish up my Avistar and get her up within the next two weeks or so,
I just need to order some replacements I lost... :\
Yeah, we moved, and the movers werent very respectful.
They literally THREW my box with the Avistar in it.
If my dad wasnt right there, I would have nailed that guy.
I ended up having to reglue the rudder back on.

HI
FROM your engine list you should be fine with a glo fuel with 10-15 % nitro i highly recommend MORGAN OMEGA FUELpink -i fly for 20 years on the 15 % and have to do little regarding engine repair it keeps the insides of your two cycle glo engines newi do all my own engine maintenance and engine repairsso i speak from hands on experience REGARDS TONY

Just a heads up on the MDS, I still have a few under the bench. After struggling with the Many Dead Stcks it finally hit me, nitro in Russia was a high end product and probably not many people there were using nitro at all. I borrowed a cup of FAI fuel from a friend and shazam!!!!!!!! Problems cured and easy to tune. The high compression of the MDS just doesn't like the nitro. I had one .68 that was OK with it but the smaller engines just didn't care for the stuff.
Gene and Dick, had to have the van window down yesterday, it just got too hot in there by the afternoon. Nice day today too, just have a bit of a breeze, about 15-20mph. Supposed to warm up by the weekend, only in the 60s today! Kidding aside, stay warm and safe!
Gene

Shoot Gene, we drive with the window down until it gets below ZERO!!!

I don't... brrrrrrrr [:@]

Hey, Gene.. Gray-Beard Gene.. I wonder if that was the problem with my Evo 1.00NX. I could never get that engine to run longer than about half an orbit before dead-stick.. and that was with S&W 15% nitro.

It worked just fine with all my other engines, they were/are OS's.

CGr.

So I cant use Nitro in my MDS... what do I use?
<br type="_moz" />

I guess you've never tried it then because that's my standard running-in brew and for a Fox 35 (for instance) the manufacturer recommends and makes a fuel with 29% oil.

The point I'm trying to make is that he has several engines that are at least 40 years old and they definitely need the extra oil. This isn't guesswork either. From personal experience, I was running an engine with a cast iron piston one day and luckily I was checking the head temp. When I saw it climbing past 300F I knew something was wrong. Duh, I'd accidentally used some 20% all castor fuel so I swapped to my 25% all castor and the head temps dropped to 245F.

I guess if they say you can't use nitro in that engine, by my calculations a gallon of 0% nitro would work unless my calculations are off. Some say use nitro, others say not too. Welcome to RCU.

Campflyboy05....read this about your MDS engine....

big dan

Sure you can but I would try 5% first. My own feelings about MDS, they were Russia's way of getting back at us!!! I have had three of the .58s and two of the .68s. I was OK with the .68s, not great but OK once I figured out there compression/porting and the nitro thing. The problem I had with the .58s was not just running but the castings. Two of them broke right at the case where the muffler bolts onto. Once Horizon even sent me the new improved carb, it was still crap!! Horizon quit selling them in about a year?? After every broken .58 Horizon just sent me a new engine. I have a new .58 under the bench in the box. I ran it a couple of times and said the hell with them. The term Many Dead Sticks is just what the guys called them. When you get one to run they are great. I just no longer run two strokes often and when I do it's the SK .91s from Kangke.
Dick, I haven't a clue about the Evos. I have fooled with the smaller ones and they were OK after I removed the limiters and was able to tune them. I can't recall ever working on the 100 at all. I just don't see many of them to judge. I had a Moiki buddy so when I was in doubt I just borrowed fuel from him to run tests with FAI or 5%. Give it a shot if you too have a friend like mine. Better to borrow then get stuck with a gallon of fuel you will never use on anything else.

The fuel you use is like a lot of other things in this hobby. You are going to get a lot of recommendations, but what suits you best will depend on a lot of different things. Plane, engine, flying style, weather, physical location, and many other things can affect what you use. What works well for one person may not work well for another. Your best bet is gather up the recommendations here and then try them out to see what works well. For your application I would recommend anything from 5% - 15% fuel, either castor or synthetic lubrication. Start with those and then go out and fly each type and see what works best for you. Buying that much fuel can be cost prohibitive, so ask around at your club and see if your buddies can hook you up with a couple tanks of fuel. Try the different types and then settle on what works best for you, your plane, your flying style, and your wallet.

Thanks what I did. My fuel of choice?? Cool Power 15%. I use that in all of my glow engines, both 2 and 4 stroke.

Ken

Thanks for showing me that.
I appreciate it.
I didnt buy the engine either.
I inherited all of this a few years back when I was 13 and my friend/instructor from church died of a heart attack.
I also just found another Enya 45 and another OS 25 on top of another 10 motors. :P
I have a few others in the basement I can use on my Avistar.
