Just How Fast Is It?

batesjm · #1 01-30-2003, 03:37 AM

Alright, we all know that bits are kinda peppy out of the box (some more than others) to the tune of 1.9 mph (with a 2.2).
But here is my question Just haw gfast does your bit go? My clone with a 3.0 and 2 cells cruises along at 4.1 mph (thats with the stock gearing, taller ones on order from tiny). I want to know what you have and how fast it really is. No BS please, this will be the best way I think for newbies to decide which mods to do first. With all of the different combos people are running this should be interesting. Oh, I almost forgot, the easiest way to measure your car's top speed is on a treadmill. Just remember a bit is approx. 1/70 scale so 11 mph is MACH 1, lets break the bit sound barrier.

Let the madness begin!!!!

just for refrence

Mph Bit Mph
1 70
2 140
3 210
4 280
5 350
6 420
7 490
8 560
9 630
10 700
11 770 Bit Mach 1

That should help a little.
Thanks for the correction, Its 4 am and Im just a little slow.

Shouldn't it be 11mph=770?

how else can you check your speed? is there a way you can count tire rotations or something? could i measure distance vs. something to get my top speed?

looks like a clean job on your dual cell mod.

if i didn't hate micky d's so much, i would say...nice car.

i'm getting about 3.2 with my MS and a 2.6.
i'm using my treadmill right now(that's all i have to check speed)

hmm ill have to measure but im guessing about 6 or 7mph with dual batteries suspension springs and a modified rear axle holder.
ill do the math and get back with you guys in a while.

**note fast doesnt mean everything cuz this thing is hard to control**

If you have a way to accurately time the car over a measured distance, maybe these numbers will help (if I did the math correctly):

8.8 feet/sec=6.0 MPH
4.4 feet/sec=3.0 MPH
2.2 feet/sec=1.5 MPH
1.47 feet/sec=1.0 MPH

nice pic i am getting a tri mod car cant wait

hogjowlz · #10 01-30-2003, 02:20 PM

i cant imagine a tripple battery car. my dual flips so easy.

timis2 · #11 01-30-2003, 02:22 PM

it will be my dragster

hogjowlz · #12 01-30-2003, 02:29 PM

you still need to steer some in a drag race. see my reduced turn radius thread. i havnt had a chance to fully test this yet.

zipsnbits · #13 01-30-2003, 02:42 PM

so like how exactly do you test it on a treadmil??? i have one but i dunno how to do it....would be pretty cool to know how fast my bit is actually goin!

hogjowlz · #14 01-30-2003, 02:59 PM

i can measure wheel rpms but that doesnt always translate into actual speed. also if you test a car from stop to finish that wont tell you what the top speed actually is. i think later im gona measure out 5foot on the floor and start the car about 5foot in front of the 1st marker and time from when it hits the first marker until it hits the second one and calculate that speed.

1-ya need 2 people
2- your car shold be able to go straight

get some one to control the tredmill's speed control, and your self to control the the car.
1- get the tredmill running at a slow speed (let say ~1mph).
2- place the car on the middle of the belt and hold down on forward.
3- keep on adjust'n the tredmill's speed untill the car stay in one place on the tredmill
4- read the speed on the tredmill

vola!! i guess that's all ( i hope yall understood??
