Worlds Fastest RC car record

[Rtsbasic]

The more cells, and the higher voltage you pack in there, the less amount of amps each cell has to dish out. Your probably looking at around 1500w peaks to break 100mph.

For the record there are packs out there that will handle just about any reasonable amp load without any problems. Koham 3200 20C's are one type of cell that handle large amp bursts. A 7-8 cell pack of these might get you close to what you want on the right motor. Your talking lots of $$, and in this day and age I don't see you getting these packs for free.

Btw with 8 nimh cells your not getting 90mph with your 540 6s. I have one, I run it on 8 cells often, it can get a fairly light car upto around 65mph, but no more. Any more than 8 cells on a 6s will probably kill it pretty quick.

I seen a lipo with a discharge rate over 100 amps continous not peak.

I would guess you would need a fair bit more than 14 cells!

[MetalMan]

To get a higher discharge rate out of Lipos, you parallel them. This is something that you can't effectively do with NiMh, but is one very good aspect of Lipoly. You could have a Lipo pack deliver 500amps if you wanted, assuming you had the wires to do so ;).

I'm not showing off by any means, but if you look at the people who were looking for speed records, I am one of those wierdos, and I once posted a thread in this forum that is named : My dream E-Maxx, just to make my friends over here have a picture of the Captains mind. The E-maxx of my dream has always been a full aluminum/ titanium/ steel truck all over with a ceramic bearing kit and two Schulze 40.160 each one is worth $ 600+ and each one would be coupled with a Lehner 2280/9-10 turn motor and each motor would be fed atleast by a 10+ cells li-polies. This is, but a dream of mine that would cost me at least a $6000 and I would not ask any people to sponser me, because they simply cannot sponser me and because they need to sponser themselves first. The RDX will not tolerate the extreme torque of a brushless motor at a high cell counts, since the belts will wear out faster than you may think and they will slip alot during accelerations and brakings. The 4wd that was used to accomplish a 96mph speed record is a shaft driven touring car. The motor was a reedy Sonic with cobalt magnets and 12 turn rotor. My guess is that if the car used a Neodym brushless motor at 16.8 volts it would not stand the power and what you will get is a bent center shaft and worn out crown gears. The brushed motor went easy on the transmission system, since it is a precision liteweight system designed for 95-190 watts rated motors. If you want to reach 100 mph, then go for a pan car like a rc10l3 or go for a 1/8TH scale onroad machine like a Mugen MRX-4 and convert it to an electric car using a 500 size brushless motor, at least 10turns and a 3295 controller supported by 10 cells lipos. This is only a point of view I wanted to share with you so dont take me wrong if I said something awful. Cheers.

I like how you think captain. That would be one awesom emaxx. I would like to see one 2280 with 10 cell lipo.

[nitrostarter]

Where's Promod?

[lipomax]

8s lipo and xl2400 will take a well geared and tuned emaxx to 60 mph...

I haven't been very active of late, but later this fall, I'm gonna go do more speed runs for you guys.

[captain harlock]

It has been a while lipomax. I'll be doing my own speed record very soon.

A buddy of mine MIKE BOYLAN he puts on the snowbirds every year. At one time he had the world record 95 miles per hr. He was using a 9 turn hand wound mod with 10 cells & a associated pancar in a veladrome.

li-po can't handel the amp draw and would pop

sounds like you didn't took anytime to invest in this project...

Like i said, the energy desnity is much higher with lipoly, it's not about the power of your setup, it's about the power of your batteries..

[captain harlock]

10000 mah thunder power lipo, 4 cells= 460+ dollars, but you will get 120 amps discharge from every two cells and 30+ minutes of runtime. This is IMO the ultimate lipo packs available.

Also a slight detail on sponsoring, the only way to get sponsord is in competition. You have to proof yourself first to a company that you can drive good in order to get free stuff. Do not think everyone can get anything for free trying to break a speed record. That's just unreal and you won't find anyone stupid enough to do this.

So my advise is, save every penny and break the record yourself. Then you got something to be proud of. I would not be impressed if your car goes 130 mph on free part's, big deal, anyone can do that.

[MetalMan]

To kind of go along with what Sneeck is saying, once you break the speed record, THEN you may get sponsored. But before then, I could only wish you good luck and happy saving :).

"
I need suggetsions on THE highest KV brushless motor and an esc to handel that on 10-12 cells"

It happens NOONE answered my question! Everyone just BASHED my ideas maby it was a big mistake signing up here and even posting it because your all bitches and NOONE even welcomed me to the forum all the answers I got were "It won't work" and "you can't get free stuff"

so i thaught this might have been a good idea signing up here but oh well
