Just How Fast Is It?

[eman1]

I dont know how accurate the treadmill idea would be.
just mark off a 5 foot space, like with 2 pieces of tape. Time the car through the tape, and then do some calculations

[t-squared]

yeah.....but you would need a place to get up to speed, cause the low gear ratios need time to acclerate, cause if you don't, it would be inaccurate..........

[eman1]

yea, you would have the car going at full speed when you go through the timed area. thats what i meant. if it wont get up to speed before it goes out of range, follow it around and have a friend time it through the timed area.

one of these days my friend is gona build an optical timer. thatll be about as accurate as you can get.

Nice car!

I'd drop that whole "corporate shill" thing though.

This should save everyone some math and time.http://www.rcnitro.com/rz/cars/calculator.asp you still have to figure it to scale.

i just got an rx-7 (blue), and i decided instead of a dual rechargable mod, i went for a single Radioshack 6v lithium battery mod. IT SMOKES!!!!!!!!!!!!!!!!!!!!!!!!!!! Real time in a couple minutes

[fuzzy2cell]

IT HIT 420 MPH!!!!!!!!!!!!!!!!!!!!!!!!!!(scale)

and another

I thought the McDonalds logo looked good, Any how, I just got a 4 AA holder from Radio Shack to make the 4 cell charger, i will solder it up tonight and peak my car to see if it helps.

i need a decent paced jog to keep up with mine. No idea how fast it is though. My parents must wonder about me jogging around my kitchen following my car......lol

[fuzzy2cell]

any comments on my car would be much desired!!!!!!

LOLOL THAT CRACKS ME UP MACH 1 no im not making it like your wrong that i may sound scarchastic

[batesjm]

First off, Fuzzy nice car, may i suggest that you tighten up the wires going up to the battery, but other than that, nice ride!

Second, I started this thread at around 4 in the morning so my brain was farting alot.

Third, I guess the Mc Donalds logo will go the way of the do-do.
Thats all


For now

just from a math perspective. The longer the distance you time the more accurate the calculated speed. Five feet isn't that great of an idea IF you have more space avaliable. If not, whatever works!
