Remote control cars. I am currently deep in the designing and fabrication of my own 1/6th ish scale monster truck.

{babble about my cool toy... skip to get to the question}
Full time 4WD, 20" long by about the same width. 2 remotely selectable forward speeds and reverse. approx 3" of ground clearance on the axles (solid axle front and rear) and more than 4" of suspension travel. Will have approx 3.5 HP at the crank.

Its going to be really sweet... Ill be posting pictures of CAD drawings when i complete them.

BUT i have an engine for it that runs on premix gasoline. Its a Zenoah G260RC1 for anyone who cares. And the manual calls for GREATER than 95 octane at 35:1. BUT i dont know where to get that high of octane around here (iv never gone to the track or put higher than like 93 or 'V-Power' at my local shell) . Are there gas stations that will carry that or do i have to go searching for special places?

you need to read up on stuff like this

Or try an airport, you can get 110 octane used for piston-engined planes.

You dont need kerozene?

For the RC car or for airplanes? Jet fuel is basically kerosene.

I tought that engine on RC was the same that on plane replica, my friend have some and he use kerosene.

Oh, well I'm not sure about RC planes, I was talking the real thing. However, I've never heard of kerosene being used in a piston engine. *shrug*

How much are you planning to spend?
You could always get into real rc unless you already are. Then have fun with the project. I used to be into rc until about a year ago.

Building my own truck isnt real R/C? :P

I have a Duratrax Evader ST (electric stadium truck), and a Maximum ST (nitro stadium truck).

Electric is OK, but not fast enough, nitro is awesome but the engines rev too high with not enough horsepower. (Average nitro engine i think redlines around 24,000 rpm and has somewhere 1-2 hp) And nitro is friggan $22 a gallon and each tank runs the car for only 10 minutes. Plus nitro engines are really finicky having to tune them every time you run them. I also have an Airplane with a .40 in it, and a spare .61 OS four stroke for an airplane that needs bearings.

The gasoline engine maxes about 14,000 rpm, 3.5hp and 10-15 times the torque. Its like the diesel of R/C engines. The tank i have for the truck will run it about 1.5 hrs without fillup. It will be like the ultimate large scale 4x4.

I already have $290 invested in the engine, i can hopefully get the machining for free at my college (thats the really expensive part) the diffs and such i will steal from another R/C car and the transmission is my own design


I guess i should go check out lunken airport to find the good gas? Is that where you all get your racing gas for drag runs?

Naw, I don't take mine to the track. I used to be an Aircraft Mechanic, that'* how I know.
