What is an 049 engine?
049 Engine is a 2-stroke internal combustion glow plug engine. These engines use an electrically heated glow plug to ignite the fuel/air within the cylinder on start-up.
What fuel does a Cox 049 engine take?
OPERATING GUIDELINES – ALL ENGINES • We recommend using only Cox Super Power Fuel® in all COX engines. If not available, fuel containing at least 20% oil (consisting of no less than 50% castor oil) is recommended.

What was Cox fuel made of?
What Is Cox Fuel Made Of? Methanol (40%), castor oil (20%), and nitromethane (10-40%) are the ingredients of Model Engine Fuel. A rear reed valve valve intake system was utilized in Cox’s reeds-valve engines up to 1960.
How do you make a Cox fuel engine?
Cox recommends a fuel mix containing 20% castor oil. To be on the safe side, we recommend at least 10% castor oil and 10% synthetic oil. The upside of using a 50/50 castor/syn mix is that it will help reduce varnishing and leave less oil residue on the model.

What’s in nitro fuel?
Nitro fuel has three main components: methanol, nitromethane, and oil along with additives such as anti-corrosion agents or degumming, agents added by the various fuel manufacturers. The amount of nitromethane in the fuel is typically about 20 percent but could be anywhere in the 10 to 40 percent range or higher.
How long does RC fuel last?
How Long Can RC Nitro Fuel Last? Many people change out their nitro fuel every year. If properly stored, RC nitro fuel can last for years. RC hobbyists report that 20 and even 30-year-old fuel still works fine, so long as it hasn’t changed its appearance or viscosity.
What is RC nitro fuel?
RC glow engines use nitro fuel, a methanol-based fuel with nitromethane and oil added. The amount of nitromethane in the fuel is typically about 20% but could be anywhere in the 10% to 40% range or higher. Castor oil or synthetic oil is added to the fuel to provide lubrication and cooling.
