Well, i had a schulze 18.97 with a bigmaxximum. The 9918 for sure is smoother than the schulze.. Not just smoother, but>Much smoother.... The 9918 is an underrated controller. A user on this forum has got his 7XL powered with 18 cells and this 9918. I know about a person in Germany that uses the 2240/8 (highamp model) with a 9918 on 16 cells. (and he claims it runs faster than a bigmaxximum powered on 18 cells)

The thing with the schulze i used (both of them) hit thermal shutdowns constantly, no matter what gearing, even with a fan. The schulze has got a 2-3 seconds delay before it hits reverse.

I hated those thermal shutdowns. Very annoying. I liked my savage doing speedruns, but when the 18.97 hit his thermal shutdown during one, it flips right over, because the controller hits FULL brakes when it does thermal out.. (a lack of engineering, because the transistor already are overheated and need to transfer the energy back from the motor to the controller again) Not to mention the punishment the whole drivetrain had to go thru.. (it did cost me two ringgears on the frontdiff and two pinions for that diff)

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.

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.

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.
