Any one tried this:

How does it work and is it worth investing in?

Venom makes very good products, alittle pricey for the speedo tho, if you have a GPS try using it to check speed, RED

I don't have a GPS. Do you have any idea how the Venom Speed Meter works and how accurate it is?
Thanks.

redheat8

sorry cant help you , RED

ils

No big deal. I ordered it anyway just to get rid of the thought of should I or shouldn't I.

fastcrash

it works just like a bicycle speedometer, you attatch a magnet, a sensor, calibrate it, and away you go. i have one, i love it[8D]

I'll probably have more questions when I get the thing in. Called my LHS and ordered it Tuesday.

Let us no what you think of it now I'm curious, RED

yea im thinking about buying one also... whenever i get my revo... in only 4 more weeks..
so let us know

Got my beadlock and masher in today (ordered a new set because i ran the T at ~70% throttle into the light pole and tore the axle hole of the right wheel). Don't know when the speed meter will be in but I will drop a few lines in here.

I finally got this thing installed and tested it. I mounted the magnet on the shaft going to the rear diff. I didn't know my truck could do 84 MPH in the Cul-de-sac. What do you use for circumference?
Although, I must say it's a nice volt meter.
Thanks in advance.

thats a difficult spot to see to calibrate. i have mine mounted on the rear diff case on my r-40. it made it very easy to measure the distance the car travels during a revolution. maybe you should find a different place to mount it. good luck

ils

When I first took the truck out to test the speed meter, it shows the truck's max speed was 84 MPH in my Cul-de-sac. I was about to fall over it. LOL.
I checked the mounting location and tire rpm and found that one shaft turn only turns somewhere between 60 to 65 percent of the wheel. And this is free rolling; doesn't count for cornering and slipage. I just need to sit down and do an accurate measure of one revolution of the shaft to distance can travel and go from there.

Here's a quick look at the meter: nice finish. The two halves snap together doen't hold well under shocks. I crashed my T on the nose, on the rear and on its lid a few times on asphalt and the two halves split open. It takes a split second to snap them back to gether. A little tape around the joints will help. I guess it uses the "z" plug type because the plug from my Airtronics fit in perfectly. It will measure instantaneous speed, max speed, voltage, distance traveled, and total distance traveled (this one will not reset when power off). The unit will display in English and Metric units.
Let me know if you want to know anything else.

I've heard that these are very inaccurate and are only good for getting an approximate measure. The thing is that when a car is at full speed, the outside diameter of the tires is increased enough to mess up your reading. I bet you could get an accurate reading with foam tires though.

fastcrash

i use the speed meter on my r-40, its accurate for about 2 tanks of fuel, depending what kind of driving(strait lines or lots of turning). to measure distance traveled i use a quick square, and make a pencil mark, then make another at one revolution. then, i measure in mm to get it very exact, then use my cell phone to convert metric to english. so far, ive got my far to hit 63mph. and remember, the# of rotations your tires make is irrelivant, its about the distance traveled in one revolution of the magnet.

ils

I realized that right after I noticed my T reached 84 MPH in less than 45 feet and under 3 seconds on asphalt (with stock tires).[sm=lol.gif]

savage326

ive got it on my nitro evader it works great

ils

Wow!!!!!
Didn't know someone would dig this post back up.
I haven't drive my T in almost a year now.
I miss the stinking smell of Nitro.

I heard that!! That smell make me long for wheelie!!!!

I feel bad for those who buy the VSM, it always gives false readings, just like the rest of venom's products. I have 2 of their temp guages, and they are WAY off what my lazer temp reader tells me. one is 20 above and the other is about 15 degrees UNDER the real temp.

I almost started a deal with Venom Racing, but after testing their products, i waved at them and said goodbye.

rccars411. That link in your signature downloads 2 trojans to your pc, 1 dowloader trojan and 1 redirector trojan. Just thought you should know.

yip it works but it takes coustom modification, buy it man!! dont be suprized about the speed though, you are moving slower than you think
watch the wires though, i pulled mine so its out of order [:@]

kxracer704

mine doesn't work too well...it says my t maxx only goes 24 mph and i know its going faster than that..i have it mounted onto the driveshft and the sensor mounted ontot the cross brace for the chassis..someone help me please if they know anything.

wow is this a slow thread! look at the dates from the start til now!
