Engines Plugs Mufflers Fuel > Clean burning fuel ??????

Currently i'm using CP 15% with excellent results, but my LHS has now run our of stock and will not be ordering it in the future.
One of the reasons why I also liked CP is that is burned clean, and did not leave any brown stained crud on my shiney tuned pipe.

What fuel should I now use, that also does not leave the brown stains on my pipe??? I was thinking of using Wildcat 30%, as this is easily available in my area.

Sal,

Where have you found Wildcat in the UK??? To the best of my Knowledge as of present there is no UK distribution of Wildcat. I have been speaking with various distributors concerning getting Wildcat to the UK but as yet I do not know of anything firm.

Sorry my mistake.........

A lapse of memory brain cells there!!!!!!!!!!

Not Wildcat fuels, but Weston Prosynth 2000, is what I was thinking about. (doh!!! ) That's the one thats easy to get in my area.

I know Dave Fisher swears by it, in fact he was the one who told me to go to CP in the first place last year, and his advice was spot on. So i'm hoping this fuel will be just as good, or even better.

Has anyone had an exprience of this fuel, and to refer to my initial question, is it clean burning????

As far as I know, there are no synthetic fuels that will leave "brown stained crud" on the engine or pipe. Castor is what will do that.

Weston Fuel

Sal,

I know that Weston is the only other all synthetic fuel in the UK apart from Coolpower at present. I believe there are many modellers who swear by the Weston product however myself I would be guarded about it. Prosynth is designed as a competition heli fuel with a low oil content. While the oil may be adequate for lubrication I am less certain of how well it would sustain the engine in a lean run. I believe the oil content to be around the 7% mark (this is quoted in the opening news on Cyberheli) which is less than half CP's oil content. Also I have tried asking Weston what the oil content of the fuel is and they will not disclose this to the public. This is reason enough for me to be careful of the fuel. I am not slamming the product because I'm sure it works, but at the same time unless I know what is in it I won't be using it. While its ok to put fuel in the car without knowing the exact content of the fuel, there are standards for which Petrol/Diesel have to meet to be sold. For glow fuel there are obviously no such standards.

If you try the Weston Fuel I would expect it to need a leaner needle setting due to the fuel being thinner (less oil) and more power because there is more fuel and less lubricant. I don't know how long the engine would last on such a low oil content though.

Hope this may be of use,

Not quite right, there are two types of Pro Synth available Pro Synth 2000 and Pro Synth 2000 Competition, The Competition is the low oil content version the standard Pro Synth has plenty of oil in it, I don't know the figures but trust me it leaves plenty in the engine!

The other advantage is Weston fuels are they are measured by volume so you get more nitro than Coolpower with the same %age label.

I've just started to test run my OS91 with Pro Synth after running Coolpower in all my engines for the last 2+ years it seems great so far and the best bit is I live a couple of towns over from Weston and can head over and get what I want mixed up on the spot.

So is Prosynth 2000 the one to go for???

I assume the Competition mix should be stayed away from???

If I go from say CP, and then directly to Prosynth 2000, with the exact same nitro ratings, what difference can I expect??

- Will I get more or less the same power???
- Is it as reliable as CP ???
- Does the needle setting change much,(as compared to CP setting) once Prosynth is in the tank.

Sorry, But I'm very particular with my fuel, as in the past I had too many flame-outs, due to using poor fuel, until CP saved my life.

Thats why I'm reluctant to let go of it, until I find a Fuel which is the same, or better than CP.

Sal,

I am aware as Andy mentioned that there are two Prosynths, the competition and the 2000. However the low oil content I was referring to was for the Prosynth 2000. The competition is (allegedly - nobody knows cos Weston won't tell) less oil still.

As to what to expect...
More power, due to the lesser oil content of the fuel, particularly if going from CP30 with 22% oil to Weston 30% with 7% oil
Is it as reliable as CP? I don't know about this I'm afraid. A friend uses PS2000 in planks and doesn't have many problems, compared to CP in my helis where I don't have ANY problems.
The needle setting WILL be leaner due to the lower oil content
I would also expect engine temperature to rise some too

While I accept Andy's point that CP is mixed by weight, Morgans would not still be in business if they didn't adjust for the specific gravities of the oil/meths/nitro when mixing IMO so I don't think that is too valid a point on the whole.

YMMV, but I considered this move and stuck with CP because ok its taken a while to find out whats in it, but now we do know. Weston we don't know and with Weston UK's current attitude we never will. Everyone has their own fuel preference and everyone believes theirs is the best, but really if you got something that works, then don't change it.

Myself I am working to bring Wildcat fuel to the UK as having read the reports of Gordie Meade and others here, I believe it to be at least an equal, if not superior to Coolpower, and the contents are on the can. In all honesty I think the UK fuel companies still got lots to learn about consistency compared to the USA big three (Morgans, Wildcat, Powermaster).

Regards


Chris

Model Technics do have
all synthetic blends that burn clean.
RTF (Ripmax Team fuel with Maxilube) ,Helimix ( 15% EDL) and Bekra (9%EDL & 9Klotz).I'm not sure if Bekra is truly clean burning though as there are two types of KLotz,KL200 and super techniplate
,one has
supposedly cleanburn castor in it ,like Irvine fuel uses (which carbons up quite quickly and stains exhausts)

There is also Go-Glo fuel that uses 15% ML70 (that purple ****)
but i've found ML70 doesn't cut it in heli's compared to more modern synthetics,maybe it would if more oil was added,ML70 is quite cheap.


I've tried Prosynth 2000 too,what i couldn't get my head around was the engine smelled hotter after the flight but it seemed to run cool enough in as much as the revs never faded for the whole tankful.

We had been using the Prosynth 2000 for a long time till about April when we all switched to the new Prosynth Comp. No problem there, my sponsored pilots had been in quite a few contests with Webra 91 running this new fuel and had gotten pretty good results. I would say we had seen at least 200 gallons of these fuel burnt up close amongst some 6 different engines. None of them showed any irregular or pre-mature mal-function or failures. General customer comments are that this fuel burns cooler and has more punch.

We will start selling this fuel as soon as we clear out the original Prosynth.

Sooner or later there will be regulations governing the amount of oil you can use so may as well start now.
