Diesesled FSARF

This weekend, I put several flights on my ARF Flite Streak with a .19 diesel for power. Very nice! I used a 9x5 prop, and it was turning 9800 on the ground. Lines are .015" cable, 57.5'. I will try 10x5, 10x6, and 9x6 sizes in the future. The diesel is some Indian make, not anything you ever heard of. I just scored a PAW .19, so I will probably substitute that soon just to try it out.

I suspect that a .15 diesel would be adequate if you made up a proper set of lines (.008 solids are legal, but I would probably go for .010) I may yet try my C*x Conquest .15/Davis diesel conversion on this model.

Oh yes, 3 ounces of fuel is WAY too much! I think the original tank may actually be adequate.

My FS has the PAW.19, 60ft.015 lines. Have tried a 9x6, 10x5, & 10x6, to date my choice is the 10x5. The 10x6 accelerated too fast out of maneuvers while the 9x5 resulted in the plane flying too fast. I'm using the tank that comes with the plane which if not the right size is very close.

The PAW Diesel .19 seems to be a very good match for this plane. The Cox conversion I would expect to be too fast for aerobatics.

OK Larry,

I can't stand it. Being a diesel nut I have to know. It's got to be an Aurora or a Sharma engine. If it's a Sharma, it looks very similar to an old PAW.

Tell us please!

Fred

Larry probably has a Sharma they aren't too bad considering. The aurora look a lot like the old A.M. motors. Some of the Indian motors may look a little rough particularly the early Mills copies, however I never had one that would'nt run. You can't say that about the Chinese CS diesel, by that I mean the cheap series. Their quality went from horrible to absolutely mediocre. Dennis

Dennis,

I certainly agree about the quality of the 'cheap' plain bearing Chinese diesels. I understand these were made over a number of years by different people and have designations such as 'Silver Swallow' and 'Yin Yan'. I think the last producer was or is CS. My 'Silver Swallow' 2.5cc did not have enough compression to fire unless I used at least 1/3 straight castor oil in the fuel mix. Maybe the piston will grow as it is run in???

I've heard really good things about the Sharma engines but don't have one myself. Ed Carlson stocks them (in several displacements), so I may just buy one sometime to satisfy my curiosity. Most of my diesels are PAWs and their quality is quite good. Plus PAW really stand behind their product (very personalized service).

Fred

It is a copy of the PAW. There is no marking on it other than the word "India".

Larry,

This is a Sharma .19 from Ed Carlson's website. Does your engine look like this?

Fred

Sure does!

I have an OLD F.S., bought at a garage sale. My MVVS .15 flies it very nicely...a really sweet running, easy starting engine.

Diesel or glow?

Larry,

Is FSARF the sound of your diesel from India?

Ya know, they've still got slave labor over there, although they most definitely would not if they hadn't kicked the Brits out.

Please quit promoting diesel-powered ARF Flite Streaks. I am tempted. But I've already got two of the things, powered by glow fuel, thank you very much, do not need or want a third.

Still waiting for a report on the Associated hardware...

stinky too.Yuk

Sorry, I haven't been able to get to a hobby shop lately. 93 b'day for mom, b'day for daughter-in-law, work (a 4-letter word, you will note)and, occasionally, some sleep have gotten in the way.

work (a 4-letter word,....... With no redeeming social value either.
Nitro fumes can never compare to the heady aroma of eau d kerosene.

Hi Larry. A reasonable 15 is quite o.k. in a Flight Streak. I'm currently flying one with an ABC Oliver Tiger 2.5 repro with silencer, on 62 ft lines. Haven't timed it but clubmates' comments are that it is fast. Actually for convenience it was on 18 thou lines on a U-Reely, which surprised them somewhat.
I had to build this for nostalgic reasons. The second contest I ever entered was the Criterium d'Europe in Brussels, in 1959. My first had been our Nationals that year, and I came 7th. I went to Brussels with school classmate Kevin Lindsey, who subsequently designed the E.D. Power Pipes, the first commercial tuned pipes for model engines. He was current Brit speed champ in '66, and was the only other competitor (with Wisniewski) who used a pipe at the Swinderby W/C's that year. When we got to Brussels we found the Brit team had only two members, so I said to Team Manager Pete Wright "How about me building a model and flying". O.K. says he, so we went to Henry Stouffs' model shop in the town, bought a Flight Streak kit, I borrowed Kev's Oliver Tiger, and we had the model back for processing six hours later. Those were the days! The 2.5 was adequate power back then too.

You sneaky laddie, I'll bet the ABC Repro Oliver is something you make.

OK, what does one cost? How does it perform compared to a current 1bb PAW? Are they currently available? And so on.

Oops. I've been rumbled. I did try not to make too blatantly commercial! Yes Larry, it is an engine from my range. It's not exactly cheap, £136 the engine, £11.90 the muffler. Prices include International Recorded airpost.
PAW's are so multitudinous in variety. Basically you get what you pay for. I think the ABC Tiger will be faster than a single BR PAW. If you go for a honking £250 PAW, I think that may be faster, even though it's steel.
In my message no.14 re Kev Lindsey I should have said he was the only person other than the Americans who was using a pipe, it was not solely Wiz of course, although he was the man behind the U.S. effort.
Thanks for your info on the (non) diesel Cox by the way.

Knew I had some info on the ABC Tiger somewhere. One satisfied (U.S.) customer reported "Using a 9-4 Taipan prop it readily turned over 13k without pushing it, i.e., comfortable compression and just a little rich".

Guess I better stop frittering my pennies away and start saving for an ABC Oliver. It sounds like it costs about the same as "old" Olivers on e-Bay. I presume it has improved performance and reduced vibration by comparison? I would also hope it is head and shoulders above the CS replicas?

Tell all!

I think you'r more or less there Larry. I always think of something I should have said after I send the message. It occurred to me I should have said my repros are usually somewhat cheaper than even well used originals. Over here people are asking (and getting) £220/250 for nib Tiger 3's. At the Gildings auction last year a nib Major went for £360, but these are rarer than Tigers of course. There's a Tig3 on e-b at the moment, and I will be informed of the selling price in due course. I'll let you know. Cosmetically it looks like a nice 2nd or 3rd variation.
You are absolutely right about more power and less vibration.
Comparison with CS? CS not in the same league. My experience is quality can be so variable. A good CS can be OK, but if any serious tuning is done, components start to fail.

The Tiger 3 on e-b went for $367, about £217. I reckon this is a bit high for a "not-in-box" engine, but not as high as I thought it might go for on e-b. Whatever, ain't mine good value! heh heh;)
