Thank you

Hi boolat,

I used to mix together 50-50 baby oil and liquid paraffin
The baby oil smokes well and doesn't seem to do too much damage to the covering and the paraffin gives the smoke this nice white density

Some people also use automatic transmission fluid but I think the residue is very hard on any covering underneath your plane

Where do you get or how do you make "liquid parafin"?

Liquid Paraffin = Kerosene

Here in the West at least, I think Kerosene is going the way of "Mineral Spirits". Gone with the wind!! God I hate the EPA....

Automatic transmission fluid tends to be expensive also.

I think there is a difference between countries what is sold as liquid paraffin.
Kerosene is a different ting here. Liquid Paraffin is thin clear oil often used in the food industry for machinery. It has similar viscousity as say 30w oil. I used to buy mine from the local chemist in 1L bottles

50-50 diesel fuel and concrete form oil works quite well. The form oil is not all that pricey.

boolat

Hey Vasek, I used to use this mixture with 4-strokes and later with gassers.
I never tried 2-stroke engines and smoke.

I used to wrap the feed pipe for the muffler two or three times around the header before the infection point to pre-heat the oil.

Concrete form oil is the oil. Sorry if I was less than clear in the suggestion. I do not recall the exact product name or it's MSDS contents.

Thanks Tony. That was it.

I have been through some searching for it and I have found out that all the info brings to mineral oil.
Mineral oil is a petroleum derivative that can be called:
Baby oil
Liquid paraffin
Petroleum jelly (low viscosity grade)

The oil used for the food and textile industry machinary is something else; it is polyakylene glycol ether. It smokes too but not as dense as mineral oil.
Kerosene, diesel, vegetable oils, ect.. can be substitutes for other applications but have nothing to do with generating smoke for aerobatic planes.
By the way even the real aerobatic planes use liquid paraffin.

So eventually my buddies and I found liquid paraffin from a local chemicals distributor (50 Kg drum minimum sale). We gave a try and everybody said that they had never seen such smoke trails before.

PiccoLino,

you only use the paraffin ?
mixing with the paraffin ?

thx
