Recommendation?

Hi Serum,

Thanks for the response. I've heard many a negative comment about Schulze, especially regarding their service.

You are comparing two different motors, the low budget version of lehner with a high-end aimed plettenberg.

Though, the XL3100 is a serious motor, you might as well look at the 1930/1940 motor of Lehner.

The 1930 series looks very efficient compared w/ the 3100XL. It's a few grams heavier but not so hard on the controller or the batteries (and consequently the runtime), the voltage constant is close too;

Basic XL 3100 1300 Watts 80 Amps 3100 215g
1930/6 1200 Watts @ 30 Amps 3483 230g

I assume by the weight that perhaps the 1930 series has a little more torque? Wish Lehner would post similar motor specs that others do (Rm and Lo).

BTW, where would I get a 1930?

I am a personal fan of BK instead of schulze. Look op the thread about the plettenberg motor, and you'll see what i mean.

The maxximum is not working properly with the 9918. The MGM controllers do work fine on this motor though.[b]

That's my understanding as well. Seems the 9918 isn't so compatible w/ the 4 pole design of the MAXXimum...anybody using the 18120 w/ the MAXXimum? Is this a BK design issue w/ 4 pole motors or can the "issue" be compensated w/ more voltage?

It is a nice motor, but lehner is simple more bang for the buck.. (for sure!)

with 14 cells, your better of using an Ubec.

So maybe the 9918, 1930/?, and 14 gp300 matched (1.17) will provide excellent top speed and good runtime.
