anyone try this out ?? just wondering how it compares to the speed meter and a inductance meter.

apples and oranges or is it bananas

If it is the same concept as the speedmeter, unless you have a bunch of rotors, its kinda pointless.. 99% of the people i have heard have them or used them think it is not really needed.. I have also never heard anyone say they ran better because of a meter telling which rotor is strongest.. Although there is alot of stuff in this hobby people dont need, so if you think it will help buy it.. The price seems reasonable, compared to the outragious price of the other one mentioned..

Comparing these three pieces of equipment is like comparing an apple, orange, and a banana.

The inductance meter is used to test the coils on the stacks that are wound in the can. It really can't test rotor strength. A guass meter is what is used for this and is the best alternative if money isn't an option. If you got a fat wallet, buy this one.

The Speed Meter is pretty precise from what I have personally tested and from testing with other highly rated/skilled racers. I have seen a difference in a 5 minute run with a rotor that was 45-50 points stronger. This is mainly from the 2 minute mark till the buzzer. When the magnet is stronger it carries the times further due to decreased heat build up. In a previous post on another thread I made mention to a bad armature right out of a package that wasn't checked prior to running. I was not at the race track to test this rotor and the individual chased the chassis/tires thinking that was the problem. To prove my point even further this particular rotor ran fine for about 45 seconds on the race track then took a tremendous dive dropping six tenths of a second by the end and twice the motor thermaled. This rotor was shown to "Novak Charlie" and it was worse than any rotor he had ever seen.

The other Meter mentioned doesn't look like it is precise enough to make a difference when comparing rotors. It does however, look like it would tell the difference between a terrible rotor and a good one.

Mike, Once again after reading years of your post's I once again shake my head!!! About the only thing you said with merit is "Unless you have allot of rotors its sensless, or something to that effect?" I would agree, But your "OUTRAGIOUS" comment is nothing short of narrow minded to the cost of Gauss Meters!! ZUBAK

Zubak i was not ripping your set price, i know they are expensive.. I was just stating for the price it cost it isnt a must have item.. I dont know the street price on them, but i do know from the cost to retail, your making plenty of profit.. anyway..

THEN YOU HAVE NEVER PRICED A TRUE FULL SIZE GAUSS METER??? WE USE ONE HERE AT WORK FOR TESTING FIELD MAGNETS IN LARGE ELECTRIC MOTORS AND THEY CAN RUN INTO THOUSANDS OF DOLLARS!!! JOHN'S IS A PRETTY ACCURATE UNIT FOR SUCH A SMALL PACKAGE!!!
AND IT IS WORTH EVERY PENNY!!!! :thumbsup: :thumbsup: :thumbsup:
