if you dont mind me asking, if this is just in an open parking lot what does it matter? If you aren't racing more speed just means more costs in broken and worn out parts.
Well its just an idea, would be cool to have something that does some crazy speeds. So the Novak set-up isnt capable of doing such high speeds then I guess. What is needed for higher speed? A higher voltage li-po and an ESC and motor that can take it??

Raven, no one can answer your question based on the information you have given us. It is obvious that you have something specific in mind.

Before you can get a good answer, please provide the following information...

- Exact Make/Model of r/c vehicle
- Exact type of racing surface (include size of longest straight section)
- What tires you are using.
- What body you are using.
----------

Making any r/c vehicle go fast in a straight line is relatively easy. Racing an extremly fast r/c vehicle is a different matter. Unless you are running on a large oval track, extreme speed isn't practicle. While 60+mph looks cool in a straight line, it doesn't look so cool when your car won't turn and you smash the wall at the end of that straight.

The only vehicles that I know that race at extreme speeds are nitro 1/8 on-road cars at very large tracks. Here is a link to a large 1/8 scale on-road track in Ohio (near Cincinnati) - http://tsrcar.com/garage/track/track.htm.

What kind of speed are you looking at trying to get and then maybe we can help direct you to what can do that. I know Traxxas advertises some of their vehicles can go 70mph with a 11.1v lipo pack. Most electric TCs aren't setup to do top speed runs on an open parking lot. Most are setup to race where the speeds are less then 40mph generally.

Most RC drag cars use a ton of cells to get lots of voltage and they run them for under 10 seconds.

Just be safe, a fast moving RC car hitting a foot or ankle could do some major damage.

The only thing needed for high speeds is large enough gearing and a long enough straight to get it there. However, the problem with this scenario is that typically the average R/C surface transmitter doesn't have the range to control a car over the distance of a speed run. This primarily is because of the transmitting point being so close to the ground (person holding a radio) that it limits the effective range of any transmitter.

Not trying to discourage anyone from going fast, but speed in r/c is always relative to where the car is being run. A car doing 30mph on a closed circuit will always look faster than a car running the same speed in a parking lot.

Im just trying to get an idea. Im thinking of making an electric dragster for speed runs or like I seen on youtube a TC4 doing 120mph. I just couldnt understand y my xvl would be faster then an on-road but after someone said there all set-up to do an average of 40 I understood.

This question reminds me of the most famous RC question ever: "How fast will it go?"

In a touring car at a drag strip at one of the top speed events held recently someone running a 3.5 and GTB with a 7.2 V pack went 83 mph.

I think that will more work, better batteries, and perhaps a different type of drive train (the vehicle was a shaft drive touring car) higher speeds can acheived for short specialized speed runs.

If you want to go run at 120 mph for 10 minutes I don't think that there is anything that will accomodate you.

But if you really are just interested in short dragster type runs you should be able to get quite high top speeds with the GTB, 2S Lipo, and a 3.5R motor.

Yes I really have my eyes on short dragster type runs. Anyone know a good set-up or can link me to where to buy?

Any help on a top speed drag set up for the 3.5? Something that capable of doing atleast 60-70 on a 7.4V Lipo?

Tim did his with a 7.4V Lipo. If you are really interested in the drag runs, you will be looking at10-20 sec runs. Nothing more.

You really need a local strip, or very flat car park.

If you join www.rc-isc.com you can message him about his setup.

Wow that website is something. There really is a whole class of drag RC car drivers and all the fastest cars are electric!! Yea I think im gonna join that forum n get into it.
