if its gonna be nitro it needs to be this.
 

now that brushless is the new hot thing of RC whats next?

how about these small block v8 and v12 nitro motors? have you guys seen these? pretty cool for a nitro. most of them would fit 1/5 or 1/4 scale cars but the v12 looks like it would fit a 1/8

That is cool. It looks like ti would be so much fun to tune....:no:

Check this one out.

OMG!!!! I think I have found my goal for 10 years from now. Those are some serious time and money investments. Great machining and attention to detail. I wonder how they are controlling the ignition spark? Would almost have to be purely electronic, rather than a cam driven system - but I could be wrong...
Wonder if I could get a diesel made....

compression ignition not spark silly

these have been out for a while. thers some guy on youtube whos building a 1/5 grave digger with a V8

The V8's definitely sound better (not that constant mosquito drone), but BL still seems to be stronger. I think if you get an equivalent horsepower electric system, it will still far outclass the V8 simply because of torque. But an electric system that big will probably be much more expensive. But really, it doesn't look like cost is a consideration.

FYI: Moved thread to the general nitro section...

I thought on one of those vids I saw something that looked like wires running to each cylinder. That would indicate to me that there was some sort of spark system.

Those wires are probably just for the glow plugs. With a central ignitor

I came across these a couple years ago, there are several copies of the videos on youtube. I do beleive these are spark ignition motors, not compression at least the V8s. The second video/ first V8 is simply a scaled down Chevy V8 for the most part. The last video is a blown alcohol motor just as you would find on a top fuel drag car, dual magneto spark ingition and all. My friends and I had thought how cool it would be to make a RC car or go cart with one until we really started looking into them. Found the website for the guy that makes them. They are pretty much a novelty item and thats about all they're worth. First is the price tag, the standard v8 started at about $5k and the blown alcohol was considerablly more. Second was the HP ratings, the standard V8 was only about 5HP. For $5k I could buy a GM crate motor and stick it in a Chevette and have a car running around a 12sec 1/4 mile. Or put a 4cyl car motor on a go cart! All in all they are really cool but thats about all they are

the multi cylinder nitro motors are compression ignition. (connellys and others) but the scale v-8s I assume have a spark and I assume run on gas? If you think that was a mechanical marvel check this out: http://www.youtube.com/watch?v=6AQFRWgW9bk

a 1/3 scale working ferrari. working clutch, working manual transmission, real ferrari sound, just awesome

Just amazing. Making detailed parts in full scale is time consuming enough - when you have tooling that fits the application. Now scale that down to where everything you use to build requires custom tooling, its just amazing. People that do that are an inspiration.

:gasp::gasp::gasp::gasp:

THAT IS SICK!!!! All I can say is wow to that, even the tach works!

Throw in a reciever and and some servos then it would be even cooler

....that guy must not have a social life :LOL:
