# Thread: speed 'maximum x0-1 ?

1. ## speed 'maximum x0-1 ?

hi

I have a question for you experts

what is the speed 'maximum that can' get to the car?

thanks

2. unknown. at the moment.

3. If you take the theoretical translucent equation for any given drag coefficient and you divide that by the constant lateral insicer of the force variable then put the xo-1 on a space shuttle and send it into orbit you can easily reach 17,500 mph or more!!

Alas, if you are stuck with terrestrial speed runs right now no-one has pushed it to the max limit. Check out the thread title http://traxxas.com/forums/showthread...one-s-Gone-Yet and see what the fastest people have gotten so far. Beyond that it is anyones GUESS.

4. Fastest I've seen posted is 106.

I think PeterV said they had seen 113 in testing.

A proper 8s setup with a good venue should be a 120+ car.... but so far I'm not aware of anyone going faster than what the car can do stock.

But take that with a grain of salt... its not like I have total knowledge.

5. POWERS dont forget about the flux capacitor .lol

6. Calculated maximum is 116.53 at 4.0v per cell. Assuming it carries a drag coefficient of. 35 around 110 in real life given every requirement is met 100%

Interesting post.... its just technical enough to be plausible.

Riddle me this... how did you calculate front surface area?

8. also you would have to have some pretty strong lipos to hold 4v per cell under load.

9. Are we talking with or without rocket boosters?

10. I'm going to toss the mamba system and use miniature gas turbine for power. Should be good for 200

11. a few people have hit just over 100 and that was with the car lifted off the ground. so for them 100 might be a struggle when on the ground. but this might be down to lipo issues or something binding.

The HUH? There are more than a few videos of the XO-1 topping 100 mph on the ground. Running the XO-1 or any RC vehicle to 100 mph with the tires in the air is not a very good idea IMO.

True. True.

Hence calculated

I never said the car won't hit a 100. As for lifting the car off the ground It has shown the owners that something is wrong with there setup.

C'mon it's a guess based on optimistic theories

i guess the best answer us "experts" (as you so sarcastically put it) can come up with is that as with any other rc car, it comes down to how much money you invest in the car. That, and how wisely you spend it. Now if you dont mind, I am going to put my lab coat back on and get back to being an expert.

I think the car lifting off the ground is more due to impatience on the operators part to see the car go fast. Thus not thinking about the fact that you need a very smooth surface to run on at those highspeeds. Think about the fact that a crack in the pavement that has a 3/4inch tall bump would be like hitting a 6inch tall Bump, aka "Parking block" in a ferrari at 180mph. The only real setup to screwup is failure to put on the high downforce canards. Also trying to hit those speeds on a day with volitile winds probably would not be a good idea.

You're not an expert if you don't have a labcoat.

20. Not sure about the maximum velocity an XO-1 can achieve but there may be a RC vehicle about to achieve 200mph this weekend!

You mean a "shoe box"?

Riddles aside I think more than anybody tower can answer this question

Not sure what you mean but it didn't get over 160mph before the foams failed
