5% Nitro Fuel in Revo 3.3
Hey Guys.
I have a Revo 3.3 here in Honduras Im finishing the first galon of Gas, But I cant get Traxxas fuel here, the only way is getting it from the U.S, but the shipping company fee is $200 just for the hazmat then they have to add freight fee, thats for a case of fuel witch cost around $130, so my question is, I also fly RC planes and we use 5% nitro S&W fuels and I have a couple of galons, could this be use in the car,? would it damage the engine or just wont have the performance ? I just drive the car around no racing or Bashin,
Thank you

RE: 5% Nitro Fuel in Revo 3.3
car fuels have more oil because they run higher rpm.
just see if you can get some car fuel localy (brand doesn't matter really as long as it's tuned right), or add some caster oil to the fuel and it will probably be fine...

RE: 5% Nitro Fuel in Revo 3.3
hey guys thanks for the answers they are just what I was thinking but wanted to make sure, so i'm gonna see how I can get some traxxas 20%, i'm getting to like these RC Trucks alot wish I could get some friends into it, maybe make a track later on. Do you guys that design/make traks are guided by rules or you just make it as u wish? I would like to make one for MT's is there any dimentions I could follow to make this ?
thank alot guys really appreciate it

So my question stands...
How/why would it hurt the engine?

RE: 5% Nitro Fuel in Revo 3.3
I would think that the drop in power would be the problem, might have to go to close ratio gearing. Maybe get some 40% and mix it with your 5% if is not enough.

RE: 5% Nitro Fuel in Revo 3.3
If you have regular Internet service, Google, "difference in Nitro fuels".
This is just my tweo sense. But if you do your so called "homework" on the nitro fuels and oil that is used, you should be able to come up with something that will equal out.
Hopefully this first section below will explain that different RPM engines burn off the castor oil which creates a lubricant. If I only had 5% Nitro I'd do some math and add some Castor Oil to it and go from there. Tuning should not be a problem. Eventually you'll find the right ingredients and the sweet spot will be hard to miss. Good Luck!
Type of Oil in Nitro Fuel
Oil in the RC fuel helps reduce friction and helps the RC engine run cooler. Nitro fuel may contain castor oil, synthetic oil, or a mixture of both. When castor oil breaks down at high temperatures it creates a lubricating film desirable but somewhat messy. Synthetic oil lubricates well at low temperatures but at high tempertaures it burns off and provides little protection. Because RC car engines typically run hotter or have less efficient cooling systems than RC aircraft, nitro fuel for cars usually uses castor oil or, more commonly these days, a castor oil / synthetic oil mix. RC aircraft fuel typically uses synthetic oil but may also use a castor oil / synthetic oil mix.
Percentage of Oil in Nitro Fuel
The percentage of oil might range anywhere from 8% to 25% with 15%-20% being the typical amount of oil found in nitro fuel. There is some debate as to whether an RC aircraft that often runs at wide open throttle during most of its run needs a higher percentage of oil than an RC car that only runs at full throttle for short spurts. An RC car or truck with a hopped-up engine that does a lot of high speed racing may need a higher oil percentage than one running a stock engine and not involved in professional racing.
[Other Types of RC Fuel
While 10% to 40% is the typical percentage of nitro in nitro fuel, you can buy fuel with as much as 60% nitro or with 0% nitro (FAI fuel). Most RC cars and trucks use 10%-40% nitro blends. RC airplanes may use lower nitro blends of 5%-10% nitro. There are also RC engines that run on regular gasoline mixed with motor oil or diesel fuel (these are engines with spark plugs rather than glow plugs) as well as jet-turbine engines that use propane or kerosene. These are specialty radio controlled models and not the kind most often sold in hobby shops.
Best Fuel For an RC Nitro Engine
It is generally best to start out with the type of fuel recommended by the manufacturer for your RC engine and the recommended engine settings whether that glow engine is in a car, truck, airplane, helicopter, or boat. Once you become more familiar with your RC and understand how the various nitro blends affect performance you can start experimenting to find the nitro/oil mix that works best for the way you use your RC.

Why & how?

You would end up damaging the motor using the airplane fuel.

RE: 5% Nitro Fuel in Revo 3.3
Hi Dave, I'm sorry but I don't know what these guys are on about. I've been running 5% Powermaster with 18% oil for 10+ gallons in two of my engines. Here is my youtube channel, all of those videos (stock 3.3 and Big Block .28) saw nothing but that fuel. The 3.3 loved it, but the .28 had to take out the shim, use a hot plug, and now it loves it too. Heck, go to the other forums and read how other guys run pump gas E85 (ethanol with caster oil) ... all you have to do is increase compression.... remove shim, longer/hotter glow... etc... The only downside is reduced power, however, I didn't notice a difference...

I say run the fuel you have and you should be fine,and with those high hazmat fees if you do blow the engine a new one is still cheaper than a gallon of nitro.

RE: 5% Nitro Fuel in Revo 3.3
I run 15% Cool Power Airplane fuel in my 2 and 4 stroke planes and my trucks. I also mix my own fuel from time to time. I would never use car fuel in an airplane engine unless you added some Klotz or Castor due to the lower oil content, but using Airplane fuel in a car only increases oil discharged from the exaust and the slight rpm loss isn't that big of deal if you are not racing in competition. When I mix up my own fuel I will mix up fuel with 5% Nitro by volume alot of times. High Nitro fuels is kind of an American thing, but in many countries Nitro is really expensive and those folks run on low or no nitro. A small amount of Nitro does help with tuning though in my experience. Of course I would be carefull not to void a warranty on a new vehicle by running something the manufacturer does not suggest.
