acetone?

So about 1/2C to a gallon. Probably want to test in smaller quantity though.

2Tbs per quart.

When you think of it like that it makes you wonder what's the point? :shrug: However... are people still spritzing armor-all into their nitro to keep it from bubbling?
 
Really? Oh yeah, like one or two spritzes of that stuff to like a quart or something... I don't recall specifically but it did keep the fuel from bubbling. I don't even know if that's still an issue anymore as fuels may have changed in the last couple years.?.? But yeah, I recall it being somewhat common knowledge. Search it. I'm sure you'll get plenty of hits.

Well the more i research and read about this topic it seems to have been more commonly used in fuels than I've ever heard of. Only in very small amounts and mostly for the stabilizing of nitro. From what I've read it helps mostly say if you have an engine that just wont run right then fuels mixed with a 3-5% acetone content will start easier and run more stable. Several guys have said that even they never proved the benefits to be sugnificant if any but did in fact run their engines for years mixing their own fuel and with a small % acetone in the mix. But can't find anything so far stating anyone still does it... Although i do see in several mentions that SHELL has a 3% acetone content in their methanol. If this is the case then any rc nitro fuel containing SHELL methanol already contains acetone in the 3% mix that I'm thinking of mixing as a trail.
 
This is an amazing read! Very interesting. And your right to many folks want to plug n play! Silly electrics! I'm guilty too, but you will never take my nitro!!!! Not sure the smell would be as good with the acetone, I love the smell of nitro!


Peace,

Well the plug n play wasn't really focused towards electrics in general but just the fact that the world is full of people who want maximum outcome with minimal input. So in other words too damn lazy to actually work a little bit more for a better outcome. Then again it does sound like I'm bashing guys who prefer electric doesn't it. Lol But I'm not, it just sounds like it.

Been runnin nitro for a few years now an I can't recall ever running into a "bubbling" issue with it

Not so much bubbles as foaming from I've read. I've never really noticed, but then again I've never run a ton of nitro either. I should go do that.. right now.
 
The Armoral in fuel is common for airplanes that are twisting all over the sky. Foaming in plane fuel could cause a bubble to stall the engine.
Nail polish remover is not just Acetone, but contains oils for the skin as well as fragrance.

that old brain is not working well this morning. but detonation is a function of octane. flash point is the temp the fuel catches on fire, setting in a small cup while passing a flame over it, and raising the temp of the fuel little by little. a high flash point makes the fuel hard to light in the chamber. ie gasoline is -40 F easy to light, nitromethane is 95 F very hard to light, making it much harder to light than gasoline. that is why nitro fuel racers use a small amount of gasoline to start a, top fuel, nitro engine.

the way i said the last post i put up, i may have mislead on what a flash point is. here is a Quote. Flash point
From Wikipedia, the free encyclopedia
For other uses, see Flashpoint.
The flash point of a volatile material is the lowest temperature at which it can vaporize to form an ignitable mixture in air. Measuring a flash point requires an ignition source. At the flash point, the vapor may cease to burn when the source of ignition is removed.
check with Wikipedia for more info.
 
Interesting topic. I've been tempted for awhile to cut overall costs by mixing my own fuel. I have a friend who does it for his airplanes and he offered to show me how to do it. The main thing stopping me is I live in an apt and have no where to store or mix materials.
 
i have been mixing my own nitro for 2-3 years. i have found little help, other than getting a nitro% that can't be bought. iam not sure i save money, but i might. to mix nitro you need a large beaker, and a hydrometer. if you friend says just use so many oz of nitro and so many oz of methanol, run, run, run, that is NOT the right way. iam sure you can find the right way on the internet. this will get you started. http://en.wikipedia.org/wiki/Hydrometer
