Default avoiding problems

Just to avoid problems in the future, it would be very much appreciated if you guys would be very careful to specify exactly what mix your running.

I doubt very much you are actually using "66% nitro", more likely your running 66% RC fuel and 34%water, with an RC fuel that consists of methanol with about 15% nitro in it.

That would yield a mix of 34% water, 56.1% methanol, and 9.9% nitro (ignoring the castor oil that is probably in the RC fuel mix)

A little clarification about what Nitro/methanol mixes are available in your area and some effort to standardize the way we talk about the mixture percentages could save some one a very bad experience in the future.

Toward that end how about a standard notation of ;

W/M/N such that above would be 34/56.1/9.9 --- or to use round numbers, 34/56/10.

For those of us that like to experiment with mixed alcohol blends of methanol and ethanol, the same sort of system could be used.

For example a mix of 30% water, 50% methanol and 20% ethanol would be :

W/M/E = 30/50/20

To make the numbering convention universal, the rule could be ;

Water % is always the first number
Alcohols always follow the water stated in order of their molecular weight.
Ie Methanol first , ethanol second, Isopropyl third
Nitro is always last if used --- perhaps require the true nitro percentage to always be enclosed in ( )

That would make the first notation for a 66% RC fuel mix appear as:

34/56/(10)



I will start another thread on mixture notation so we don't clutter this thread up.
