so any updates on this?

John Binz · #**477** 06-15-2005, 03:56 PM

Is this going to happen?

SerpentKing101 · #**478** 06-22-2005, 01:57 PM

going by the site, it wil take place after september 1st. no definite date or place is posted.

*crosses fingers for the event at Charlotte*

You know, honestly, RCCA would just be better off planning the event for a year from now. Summer has already started, and i'd bet all the major players have already dropped out. Even if it's 2 months from now, the turn out won't be good since people need to buy plane tickets and the only ones who can show up are those who live within driving distance of wherever the event is held.

Honestly, there's a lot of people who have invested a lot of money for the event, it'd be stupid to call the whole contest off and leave everyone hanging. Reserve the track for next year and make sure it's in writing

First Off, Im not ready....why....I haven't found a cost effective way to get past 100 mph. I mean spending under $500...including travel.

Second....I'm just too busy with the army sending me one way and college pulling me the other. I feel for my TC3's...they haven't seen a race track in 3 months. I'm in the process of converting to all brushless...so anyone need some motors, brushes, tote, esc's, comm sticks, a stcik battery, and some other stuff related to brushed motors.

Same goes for rotational forces, a 3 inch tire might have 80 times the force of a 1 inch tire.

Actually Air resistance increases directly until the air reaches a point where it stops flowing over the car in a linear path and becomes turbulent. then it increases exponentially and i think once a car reaches that speed will be about where it tops out. so a good idea would be to invest a little time in making your car a aeordynamic as possible to keep the resistance down and incrase the amount of speed you can gain before the air going around you car becomes turbulent.

Well you could always custom-make a body shaped like a big wedge and mount a large spoiler on it. Very impractical, but hey. Its an idea.

It's a bird! It's a plane! No, its an RC car with a Wedge-shaped body clocked at over 100MPH ---- Well theres something weird to imagine

As posted previously elsewhere...
Guys, this event will happen, planning it has just been more difficult and time-consuming than we anticipated. Or should I say "I anticipated," since this is my baby. BUT IT WILL HAPPEN, with plenty of notice. Look at it this way: you just have that much more time to build and test.

As far as the eds looking at the forums: we all wish we could spend more time on it, but the print magazines and their deadlines have to come first! And occasionally my wife and daughter like me to spend 5 minutes with them as well. The pressure! : )

I'm not saying you have no right to complain--you do. But rest assured, there WILL BE a WFRCCC!

PeterV · #**484** 09-13-2005, 06:13 PM

Hopefully I can update y'all with something more concrete soon!

Man, the name's a tongue twister

InitialVelocity · #**486** 09-18-2005, 03:14 PM

Why not just find a dragstrip? The man who owns a dragstrip complex locally is into RC cars, and was more than happy to accomodate me so I could get some runs in.

microrcdude · #**487** 09-18-2005, 06:49 PM

Ok, time to put my car BACK TOGETHER, errgh. Im getting tired....i think

the bottom one hits high 90 's

WOW. nice

TimJohnson · #**491** 10-08-2005, 03:11 AM

do you have a spot for the Landspeed run yet?

Do you have any documentation?

burntslapup · #**493** 10-11-2005, 01:54 PM

GrandMotorsports Rail - Hits 0-98 mph in 132 ft in 1.5 seconds...

and just think of the mph this thing can do in a speed run

InitialVelocity · #**494** 10-11-2005, 04:27 PM

What did you use to measure Smokey? Got Proof?

TimJohnson · #**495** 10-11-2005, 10:54 PM

Sorry guys i find it hard to beleive that your HPI did 100+...He has an exahast deflector and a cast pipe...........the one with the RP motor has more of a chance.......I would like to see video, and a time slip.

trailranger · #**496** 10-13-2005, 02:22 PM

I thought speed was a direct function of power to weight ratio? I see lots of purple, and I would guess is aluminum not Titanium. I am an electric buff, so is a cast pipe better than a lightwieght tuned carbon fiber one? Maybe I should redo my TC3 with the Novak HV Maxx and toss in a Higher KV motor. After switching from senorless to sensored, I really enjoy throttle control and breaking. I would like to use BoostCaps, 350farad capacitors. 2.5V, but they are just as expensive as Lipo systems and only good for sub 10second speed runs. But with internal resistance that low, charging is fast.

burntslapup · #**497** 10-19-2005, 01:29 AM

I to find it had to beleave that any of those HPI's have seen 100+mph... your right trailranger speed is a power to weight thing, that's why you see electric rails running 132ft in 1.5 seconds at 98mph using GP2200's rether then the new GP3700's... the 2200's are smaller and lighter then the 3700's... all that purple does look good and I can see he spent some money on the car it's to bad all that turned the car into a BRICK... Dude take some metal off and add some plastic and carbon fiber it'll go faster.... Trust me

92gsr · #**498** 10-23-2005, 11:14 AM

speed is a function of power vs. aerodynamic drag. acceleration is a function of power vs weight. acceleration is important when determining the top speed of an rc car because of space limitations. the car has a small amout of time to accelerate to top speed before it has to turn or stop. with enough space weight has no impact on top speed.

ssmokey24 · #**499** 10-23-2005, 11:26 AM

i dont have a cam to record but here in south florida we always have drag races
and one of our best friends work for the lake placid police department and thats how we get the speed on the cars

TimJohnson the supernitro with exahast deflector and a cast pipe. is faster than the rb one it has a rb mods novamega m5 and a novamega o86 pipe the other has a rb engine and a 086 rb pipe

that is so true, and when he says its in the triple digits, i think he's talkin bout price actually...lol
