I LOVE THIS MOTOR!!! I got to run a full pack through it, start to finish. I wouldn't want to run a 30 min main with my 5000mah pack, it dumped right at 30 min. (was getting 20 min with XL motors). I did put a small Integy clip on heatsink on it. It looks like this motor runs at 175. After 15 min I had the temp up to 175, checked it a bit later and it was down to 165. Temps throughout the remainder of the run were from 160 to 175, never got any hotter. Mamba temp at the end of the run was 165, and battery was 120. I think we have a winner! Just wish I never spent the money on the two XL motors, trying to save some $. Now I have to retune the suspension as the buggy is so much lighter now, but I can live with that, lol.

It sounds like you have hit gold. Those temps might be considered to be a bit high by some, but they are within acceptable range.

I am very anxious to try out my Neu 1512. I hope that my temps in my truggy are about like yours.

The 1930 and the 1512 are roughly the same size right? rotor?

I remember Serum talking about the 1930 being a very quick and responsive motor in a lighter truck, I didn't really believe it could be though. I can see why now...

AAngel: Let us know how your Neu motor performs once you get it back?

I was a bit sceptical that the 1930 would be enough motor. But it has no problem running the light weight buggy.

I need a little input on battery selection now. The 5000 mah maxamps runs right at 30 min so I will need a 6000 to go for a 30 min main. Only thing is, all the tracks around here seem to run 15 min mains. I am leaning towards the Flightpower 3700's to further reduce the weight. They will put me under 7.5 lbs and make left/right balance nearly perfect. The discharge rate at 25C is nearly that of the maxamps 5000 at 20C. I think someone here is running Flightpower 3700's, I'd like to know how they work out. Or I could get the 4500's at 30C but they are pretty spendy! Any other thoughts on batteries for this motor and light buggy appreciated.

Great to hear you are happy with it. As for the battery question, I dont run the flightpower packs but I run packs that use the same cells in the 4350mah size and they are great Never even break a sweat. I would imagine that with this smaller 1930 motor setup you wont have an issue with overloading them. Plus the RTR weight will be down even more so you should draw even less current.

I think you are on the right track with getting the 3700 packs for the 15 min races and then just running 2 paralell 3700 packs stacked for the long 30min mains. Might be hard to fit 2 of the 3700 packs under the lid though.

I run 6s Evo20 3700mah packs and with the 1950/10 in my all metall SuperMaxx with a slipperential and 20/36 gearing, the thing almost makes wheelies if you give it enough throttle. If it weren't for the duct taped tires, I think the truck would have flipped, easily.

Also, the 5000mah FPs are lighter than the MaxAmps. AND WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAY stronger>>>>>>>

Does anyone have any idea of what cells are used in the Neu packs? I was on the Diversity web site and the 20C Neu packs on on sale.

Although I haven't gotten my motor back from Neu yet, I'm already anticipating having to rethink my whole setup. I've been running the 8Ah packs, but with the 1512, I should be able to start running smaller, lighter packs and still get the runtime that I need.

No, and I doubt Steve will divulge that. There was a bit of a ruckus over at rcgroups when his packs were tested against some of the popular packs available and came out on top.

The point of contention was the fact that the test was conducted by Steve and then allowed to be published in a magazine.

Yeah, by the looks of the discharge graphs, they seem to be very potent cells they use, flightpower equivalent.

I think the Neu cells are Enerland cells, which are the ones used in Flightpower.
