RE: difference between 2 n 4 stroke?
I will give this a try and say, "What Jack *****es" No really, what do think the average running temp is on a real car engine? Lawnmower?.....R/C use nitro which burns hotter to get the needed power at like 240 degrees compared to 120-140 in gasoline. Some R/Cs do run on pump Gasoline like the FIREHAMMER. I wonder how fast are they? It is a huge 1/5 scale buggy. FG also has a truck for like $1200 that seems fast. But as far as the LST, I do not think there is a GAS engine out there nor that you be impress by the performance of it.
Also I think 4 stroke being Street motor cycles gas and oil are separate and 2 stroke being motorcross Dirt bike where gasoline and oil are pre mixed.
