Exclamation venom speed meter

Does anyone have the venom speed meter yet? I just bought one and installed it, and the only thing that seems to work so far is the voltage meter built into the unit ! Does anyone have any ideas as to what the problem might be?

I'm sure you have read the instructions carefully and installed the unit as per the instructions but just in case there are a few key things you should check.

1) Is the black side of the magnet facing out? Magnets as you know have a north and south pole, if you attach the magnet the wrong way around the unit will not work.

2) Is the distance between the magnet and sensor a maximum of 3mm? The closer you can get this the better. Mine is at about 2mm and reads great. At 4mm it did not work in my case.

3) Are the large flat side of the sensor that faces the magnet and the black face of the magnet parallel to each other when the magnet passes under the sensor? It doesn't matter if the sensor arm goes off to the side as long as these 2 faces are parallel.

4) Does the magnet pass accross the middle of the sensor face? If it only just passes an edge of the sensor it can effect the readings.

The above are the main problems in setting up that I know of. Given that you say you get no readings then the most likely problem is either 1 or 2. If the readings were erratic or appeared innacurate then I would say it would most likely be 3 or 4.

It is an on board unit that will fit on rc cars of any scale. It gives you maximum speed in Km or MPH as well as distance travelled since it was last turned off and distance travelled since the unit was first installed. It also has a volt meter so on a gas car you know when to charge the battery.

As long as the magnet is rotating you should get a reading so you can hold it in the air and pull the throttle and you should get a reading.

i would think that the little magnet you mount on your spur gear with throw it out of balance. does anybody know how much the whole unit weighs?
