Take a look at the wings in front of the rear tires something to think about to help keep your car on the ground at high speed???

i beleive that guy was using a hydrogen peroxide chemical reaction engine if memory serves me correct, it worked on the principle that pure hydrogen peroxide reacts extremely violently with fine silver screen so he somehow contained this reacion and used it in his kart, i also think he died in one of those things, heard something about spinng the tires til 200 then crashing into a wall

This is all very interesting but don’t they have a form some where for go karts as I thought this was and RC form?

The event is coming up very soon. Good luck to all the contestants! I can't wait to see some pictures, video and results.

death in your own machine, thats bad advertisement lol, that must be sick, spinning your tires at 200 miles an hour!

IBJAMMIN · #**605** 07-08-2006, 08:25 PM

Well it's kinda hard to spin the wheels with a thrust powered vehicle? I think he died in a full size dragster in the 80's? not in the rocket kart.

apollo · #**606** 07-08-2006, 11:05 PM

i actually didnt specify how he put power to the ground, i think it might have been a jet turbine like a tank uses, directly drives the wheels, but im nto for sure, it was a long time ago when i actually knew about it

I just heard of this contest a couple of days ago, I will be there, 6-1/2 lb car 10-12s LiPo, Custom Brushless 6 turn motor, 3.1HP @101,000 RPM. I have done 80MPH w/ this setup on only 4s LiPo and the car was setup for acceleration not top end. Sorry won't tell what type of chassis. If a radio control boat can do 140+ MPH we should be at the 200mph mark on land, speed on water is so much harder than on land and we're not even close to the big time boat guys. They have a straight away record trials every year, this is something that should be sanctioned and done by one of the Mags (uh hum...Car Action) every year in different locations around the country.

Well best of luck to you and i support anyone thats running electric as i'm no big fan of nitro and have been in the hobby since the 6th grade and till now have not owned a single nitro. But to be honest with you, i really don't think your car is gonna come close to what the member "Craps" is running, i believe his car or maybe should i say "R/C Go-Cart" topped the speeds at a 112 MPH with a top speed of 150 MPH if memory serves my correct from reading a few posts about it. I just wish i could be there for this competition, but sadly like all major events like this, i can't make it due to myself being on a rock in the middle of the sea LOL

Believe it or not, I am a hard core Electric off road racer that has promoted a class we call Pro Truck using brushless motors and 8000 mah li-po batteries with a 20 minute main.

I don't have as much fun racing the traditional "diesel Nitro" RC cars with the glow plug and ignitor. My GAS car has a spark plug and ignition, is simple to tune and will practically idle all day long.

If the contest had stayed 28" long max, I would have built an electric car with li-pos and brushless. With the 40" long max rule, I wanted the biggest tire I could find that could take the speeds and with that it got heavier and needed more motor than an electric could provide for my budget.

mrpags · #**612** 07-20-2006, 02:17 PM

My theoretical top speed, (using 10s LiPo) calculating rollout with the rpm at 101,000 is 198mph, now i know that i am not going to get near that speed with parasitic and aerodynamic drag, but if i take away 35% for the drag coeficeients (I am just guestimating on that, I was 14% off on my 4s setup) i can concievably reach 130mph and i still have more room to go with my 12s, (hoping the car stays in one piece) that would shatter the existing record of 111mph, by 20mph, and since this is a currently available radio control vehicle, slightly.....modified, that anyone can purchase and not a modified Kart, I would be pretty happy w/ myself. I am also a hardcore racer, Electric, Nitro, Offroad, onroad, you name it, i've raced it and i feel electric is the way to go for top speed. I now have been running electric boats for the past 2 years and have applied some of the brushless LiPo stuff I've learned to some of these cars and the things they are capable of are astounding. The current crop of electric cars are not capable of handeling the horsepower of the Lipo brushless combos, so Chris Fine at Finedesignrc.com has been converting gas cars, trucks buggies and truggies to brushless lipo setups and they are nothing short of amazing, i can get my Lipo brushless powered Mugen MBX-5 prospec up to 60mph in just a click over 3 seconds, and run full bore on a racetrack for 8-9 minutes on a 4s 3700mah pack. I can put a 7500mah pack in there w/ very little difference in performance and run for 15 plus minutes, the pack can be changed in about 10-15 seconds so i can run a full hour long main w/ only 4 pitstops, right along w/ he nitro guys. Sorry to make this post so long. I only wish I had heard about this contest a month or 2 ago so i could really be prepared, I'm only going to have one day of practice, as i'm on vacation right now and wont be home till next thursday. By the way anyone know what the closest airport to the track is??? thanks.

Craps · #**613** 07-20-2006, 06:28 PM

Wow!

I hope he tests it over 100 mph before the calculator batteries wear out and he buys airplane tickets!

On paper and on the race track are 2 different things.

mrpags · #**614** 07-21-2006, 12:01 AM

LOL..... yes i should get a test or 2 in before i fly out there.....but i'll have a blast either way........break a record or crash and burn.......or make a fool of myself.......who cares we'll be racing!!!!!!!!!!!!!!!

Breaker 1-9 · #**615** 07-21-2006, 06:09 AM

If i had the money to dish out, I would most defiantly buy a car like Craps from Craps. It's one of the most abnormal R/C's i've seen or that one would probably ever see racing with normal like racecars at a race track. I mean the thing is a R/C go-kart pretty much, a REALLY fast one for the matter. Seeing that thing next to a regular R/C car there at the race would be pretty interesting.

Dustin

mrpags · #**616** 07-21-2006, 12:09 PM

just curious craps, that thing looks like it will handle pretty well too, have you run it on any type of go kart or race track???? looks prety sick, have you tested at 150mph? can't wait to see it in person, see you next week. if all goes well.

fasterthanspeed · #**617** 07-22-2006, 07:23 PM

I am just letting everyone know its really hot in Southern California. Right now its 105 degrees f. in the shade.

fasterthanspeed · #**618** 07-23-2006, 02:45 PM

Were having wierd weather in California. Yesterday it was blazing hot outside, now its raining.

GordonFreeman · #**619** 07-23-2006, 10:42 PM

If you don't like the weather in Wisconsin, just wait five minutes.

I demand pictures!

Keep your eyes peeled for the Rainman's entry. Its a unique body style for sure. Should be easy to pick out. Jim Schauer will be hard to beat.

Griz

rainmantoo · #**622** 07-29-2006, 01:24 PM

Guess I've been "outed" so to speak. Thanks for your support Griz! I think if Craps doesn't "roll" craps he'll be a tough one to beat. Sure will be a lot of fun to find who truely is the fastest. Here is a picture of my car sitting on an ice chest full of bottled water just in case we need it tomorrow. Can't get a good side view due to the 1000 pxl x 1000pxl size limit. See everyone manana, Jim Schauer

griz11 · #**623** 07-29-2006, 02:23 PM

Yea that car looks like a winner to me. One thing for sure dragster drivers go fast every weekend. Some of the other guys might freak out when they get over 80

Those are some tall tires. I'm sure you have enough motor to turn em so you should be hauling tomorrow. Good luck !!!

Griz

Craps · #**624** 07-29-2006, 05:02 PM

Was out at the track today while the "Battle of the Imports" was being run that made me feel like I was in the "Fast and the Furious" movie and noticed there is no electric out there that I seen. You guys may want to bring a generator or power inverter for electricity.

mrpags · #**625** 07-29-2006, 07:38 PM

Unfortunately due to a death in my family i will not be attending tomorrow, I am sorry i will miss all the fun, go out and break some records, maybe next year guys.
