How many of us have one or more different types of fuels for the engines that we run?

What are you applications of your fuel for your engines?

Engine type = Fuel type?

Satio 91/72 = Coolpower 30% Heli

OS 91FX = Coolpower 15%

MDS .78 = Same as above (probably should only be using 5%)

Magnum 120 = YS 20/20 (only 1/4 of a tank just to test. Used engine but after reading the manual I need to get another type)

Moki 1.80 = none yet but will have to buy some FAI

I use two:

15% (Mixed Locally at the LHS) - OS46FX, Saito 72, OS91 Surpass, OS61FX

Gas/Oil Mix - Zenoah G-26

Never felt the need to add more types of fuel just so I have to carry them to the field. The 15% works well in all my glow engines, and of course need the gas/oil mix for the gasser.

I generally use 10% Power Master in all my engines, four strokes included, but I do use 20/20 YS in my YS four stroke.

I have a 1/4 scale Cub that'll be getting a Quadra 35 soon. That'll use gasoline of course.

Hi,

I use a home mixed brew of 20% Coolpowerblue, 10% Nitro and 70% ethanol. I switched to this many mix years ago after reading an article on the anticorrosive powers of Coolpower and the fact that it doesn't gum up like castor. One of the engineer scribes to a local mag (sort of a croc hunter Clarence Lee) uses this mix in all his engine reviews and it meets the warranty requirements of all model glo motors imported into Australia.

Since using this mix I have never had to degum an engine, unfreeze a carby or do anything other than wipe the oil residue off the model. I currently use this mix in the following two and fourstroke motors OS 108, FSR40, LA40, ST75, ST90, Saito 72, Saito 100, Fox 35, Enya 35 and Rossi 60. If I mount the engine inverted I increase the nitro content to 15%.

I know castor protects better at very high temps but as I'm not into pylon or lean runs this isn't an issue for me but the castor gumming certainly is.

Cheers,

Colin

Colin, how do you know when you have to "degum" and engine[sm=confused.gif]

I carry 2 types of fuel.

I like to run 10% nitro but it is darn expensive here so I only use it in my acrobatic planes.

I use 5% in my trainer to save a little.

15% nitro Cool Power--all my glow engines (2 and 4 stroke)

87 octane pump gas and Klotz synthetic at 32:1 for my gas engine

I use 15% Mach7 in everything but the gas engines. The Saito 180 and the YS120 run well on it, but are down a little from the 25% fuel. For the difference in price I can handle that.

Always have to keep track of the amount of fuel and the type i am bringing with me along with the amount i have stored in the garage and perhaps the hardest of all is making sure i do not keep half full jugs around to long to go bad. Maybe i should go electric.

On second thought i seem to have to many different battery types for the electrics i have now.
