Enya 3 for me. Running own mixed fuel with 20% Nitro and 18% Aerosynth 3 oil.
interesting ...

mc59 here with 15% nitromethane and 15% aerosave oil + meth

Cheers

Interesting replies. Different nitro contents require different plug temperatures. The higher the nitro the colder the plug. Nobody should run an OS #8 plug on 15% nitro unless they want to sacracice performance. Anything under 22% nitro should run an OS A3 or equivalent.

Hi Dilbeck
Now that was what I was looking for a straith answer of why there are diffrent plugs and for what recomondation. Is there a chart somewere were you can see the diffrent plugs and heatranges etc??

regards Pete

Correct and thats why i use the mc59 with excellent results

We pay high prices for nitromenthane here in the UK and Europe, bit of a joke really, thats why 15% is my max, but my 15% is by volume not weight so may be higher than 15% in a retail pre mixed fuel sense

Cheers

Dilbeck, How did you come to that conclusion? If you use a hotter plug you can use a richer mixture which will produce more power and keep the engine cooler. Not to mention most of the engine manufacturers recommend an OS8 or Enya3.

For anyone to make a broad statement about plugs and nitro percentage in fuel like your link just does not have an understanding of how complex the combustion process is. There are no given procedures that will hold true for all engines. You could be undercompressed, overcompressed, loading the engine too much, using tuned pipes or mufflers, carb venturi size, rpm range, different fuel manufacturers, port timing, chamber design, and list goes on. The fact that so many use an OS8 or an Enya3 should be a clue that these plugs function well. Another point is there is no way to tell what plug is equivalent to another when different manufacturers are involved, there is no tested cross chart that makes that comparision.

Ive tried the differences with 15%, 20% and 30% nitro using OS #8 OS A3 and A5 in an OS 37 and 50 Hyper and it held true. So go figure.

I have tried a myriad of combinations and always end up with the OS8 or Enya3-4. Do a poll and see what most people are using if nothing else it would be interesting?

Like most others, either Enya 3 or OS #8. I had plugs blowing quite regularly on both my OS50 Hypers until they were properly run in so used OS #8s as they are less expensive.

Anyone can make this a complicated discussion if they work at it and over work it to the degree that its confusing and they just grab a OS #8 plug or whatever and be done with it. Try not to over complicate it by thinking to hard. I understand there are many variables to consider here as with anything. Most of us are running stock out of the box engines and have a muffler. The biggest difference is size of engine and the nitro content for the most part. One example: An OS 37 running 30% nitro with an OS #8 plug runs OK and is acceptable. Now take the same engine and put an OS A3 plug in it with 20% nitro and you have the same power but a better running, better idling, cooler running engine. As a matter of fact I truly believe it has more power than it had before. It will idle so low you think its stopped running and will do this till the tank is empty. How many of you can low idle an engine with a 1/2 tank of fuel and it will not die till the tank is empty? If not your using the wrong % of nitro or the wrong temp plug or its not tuned properly, Or any combination of the above. I spend 80% of my time in this hobby testing and tweaking VS flying, but thats what I enjoy the most. Having said that, this is my own personal experiences and others may vary.

Hi
Well you know what I will just try a A3 plug and see what happens, because I am running 15% nitro, so why not. Regards Pete

Dilbeck, Thank you for for adding fuel to the point that I stated, about the hotter plug being a better choice the majority of the time. Over complicating the situation is not choosing the plug that most will find suitable. I don't know why you would idle a half tank of fuel away, most people use their engines to fly. It was a good discussion anyway.

airdodger, Most would never idle a 1/2 tank of fuel. I did this only as a test to how well it will run when the combination of plug/fuel/tuning is RIGHT for the engine. If you get all these things right it will idle the tank empty, run cool, and the transition of power will be flawless. No harm no foul, Ive enjoyed the conversation and as always im working on continuous improvement of my helis and welcome any and all comments.

Well all I can say to that is "That Sucks"! Anyway just be sure to tune the low as well as the high speed needle.

airdodger, Dilbeck, , both my 2 Hyper 50s would sputter just off idle as I just started the spool up, many times my engines would stall, it was a real pisser, I dogged this problem for over 2 years,
2 diff carbs (60L and a 60B), 3 different pipes, 3 diff Nitro rates, OS 8 and Enya 3, all kinds of tuning, 2 years still had the problem,,
then I thought, well the A3 is hotter so I will try it,, problem solved !! and I have a very smooth and steady idle, I don't think the A3 gave me more power tho..
