DVOM? Does that mean digital volt ohm meter? If so, how do you do it?

Check it out.

They need to post the Inductance levels for the stock 13.5 motor though.

So does a lower inductance mean the motor will perform better? You know where this is going. Incoming flood of vindicated motor tuners in 3... 2... 1...

Guess I'm selling my lathe to buy an LCR meter.

Has anyone who tested the new motor want to give us some feedback?

I think inductance is something that cannot be measured on a standard DVOM. I believe it requires an inductance meter. Can anybody verify this?

The lack of positive identification will keep this motor out of our local track. Bummer. Hopefully that is something Novak will change soon.

Never mind that last post. The link to the Novak site further up answered my question.

Ran it in my TC-3 (my stock car) with the Novak GTB speedo on No.1 brushless program. Started off with my normal monster gearing and ended up going two pinions up to get the straightline speed. Driveability was good and was at no disadvantage or advantage.
Ran it outdoors in qualifying at my local club on Sunday - qualified for the A just a couple of tenths behind the person I normally am dicing with and that was on some old rubber tyres. Also had the disadvantage of being in the first heat meant one bump costing a couple of seconds and a few near misses that all add up.

Overall, I feel that Novak had done a good job and the tracks/drivers having nothing to fear. It was great not having to do any motor maintenance.

Man, that is great! I'm glad that it is so close in speed with your initial testing.

Mike,
Is this motor available to buy in the UK yet?

Not yet. They have only just started to escape in the States.

It was quite good fun on Sunday even though I was in the last mod heat and first stock heat - certainly glad I didn't need to do anything other than charge the cells and goop the tyres

Well, I tried Novak's inductance test and I can't make heads or tails out of the reading. As soon as you stop rotating the rotor, it falls to 0.00. There is nothing consistent about this test. The readings are all over the place. Can anyone else get some readings on any brushless motor and report back? I've tried the 13.5 and the Neo 3 star with poor results.

I have done it. It is pretty straight forward. The key is to turn over the motor SLOWLY while looking at the readout on the meter. Putting a great big pinion on it helps. Note the LOWEST figure displayed.

If you turn the motor over tool quickly the meter will not settle in on a figure and the readout will bounce all over the place.

The figures I got were within the ranges on the Novak site and no where near as low as the minimum readings listed.

FYI, I have an inductance meter because I wind CD-ROM based BL motors for my r/c planes. It nice to have for testing new winds and when you have 10 motors that all look identical lying around

It must be my meter then, because if I stop moving the rotor, it always falls to 0.00. It sounds like yours does not do that.

I mailed Steve about running the ss4300 motor in the 19T class for your club/winter series and he was ok with it. But I'm wondering whether to wait and get this stock motor now?
Do you know if this will be sold as part of a system? Or just the motor?
