ok guys i mix my fuel at home and use, castor, synthetic oil and rest methanol and 5% nitro,

and my engines are smoking way tooo much, its reall bad, its a white smoke, that is constantly coming outta my exhaust,

i can see the smoke even 10, 15 feet high sometimes in the evenings, how can i reduce the smoke coming out[:@][:@]?????????????????

in nitro engines does the oil burn or does it just lubricate and go out, whats causing all the smoke is it the methanol or oil

heres my normal mix

for a litre
16%oil 160ml
84% methanol 840ml
i just add some nitro into it about 100ml

theese are the oils i use, castor 927 by maxima usa(its a racing oil with degummed castor and synthetic oil http://www.maximausa.com/products/2stroke/castor927.asp and sometimes i use this when the castor 927 is not avaliable http://www.zipkart.com/acatalog/Shell_Racing_Oils.html

both the oils are very similar and are the same exact colour and with both the engine smokes alot

what do you guys think?? can i add something to it to reduce the smoke

its all the same in all of my engines!!!i got no idea what to do about it?????

the smoke is from the castor oil, castor oil doesnt really burn that well, it just smokes when burned, synthetic oils burn up in the combustion process, are you using a high amount of castor oil in your blend? and smoke isnt bad, it means your engine is getting more than enough lubrication

i know it ant bad for the motor, but it can be bad for my health right!!

no this oil doesent have alot of castor oil in it

it shouldnt be too bad for ur health since in the early days wen kids were naughty they got forced a teaspoon full of caster oil....wont be harmful to you

oh interesting!!, but i ant been that bad recently maybe thats y i have to inhale it rather than drink it

but what the hell do i do theres sooo much smoke u wont beleive it either if u saw it

I take it you have not watched a control line flier fly a Fox stunt 35 with 29% castor in the fuel.

ummmmmmmmmmmmm no i havent, do they smoke as much????

I take it you're running this fuel in a car so it doesn't have that big wirly thing up front to blow the smoke away

Once when I was running an engine on the test stand with 25% all castor I plugged a length of old radiator hose over the end of the muffler to direct the exhaust out of the slipstream from the prop. It was amazing just how much smoke there is when it goes up and hangs there. But don't worry, smoke is a good thing because it shows the oil is passing through the engine and lubricating it instead of getting burned and making the engine run hotter.

its about time i think some company came up with some sort of catalyst convertor or something for our rc vehicles
